This case study shows how our team managed the supply, documentation, warranty claim coordination, and technical report submission for ABB KOFA 12F3 current transformers used for differential protection in Bangladesh.
The client was UPGDCL (Former UEL), Bangladesh. The project started as a trial order, because the client had previously imported similar items from overseas through Letter of Credit (LC). After successful supply and service support from our side, the client placed repeat orders.
Our team handled the full process from procurement coordination to communication with overseas partner and final report submission to the client.
Client Background and Need
UPGDCL (Former UEL) required current transformers for differential protection. These are critical electrical protection components, and the client needed confidence in the following areas:
• correct specification and ratio • product authenticity and traceability • safe packing and delivery condition • responsive support after supply • technical follow up in case of field issue
Because they were used to importing through overseas channels and LC process, the client initially placed a trial order with us to evaluate our execution quality.
Product Supplied
Based on the purchase order and item details, the supplied item was:
ABB KOFA 12F3 Current Transformer (for differential protection)
ABB KOFA 12F3 current transformer
Key references seen in the project records and product labels include:
• ABB make • KOFA 12F3 type • differential protection current transformer application • ratio class markings and label data on each unit • serial numbered units for traceability
The project photos also show:
• unit nameplate labels • serial number stickers • packing condition before dispatch • crate packaging and handling condition • grouped shipment layout for multiple units
This visual evidence is important because it increases buyer trust and proves physical control, packing discipline, and traceability.
Order Development: From Trial to Repeat Business
Purchase Order
This project is important not only because of the item supplied, but because of what happened after the first supply.
The client initially placed a trial order with us instead of importing directly from overseas through LC.
After successful performance, the client continued ordering from us. Over time, we received repeat orders three times, and each order included 3 pieces (one set), making a total of 9 units supplied under this supply relationship.
This was a strong sign of client confidence in our team’s execution, documentation support, and response quality.
What Our Team Managed
Our team handled the project execution in a structured way. This included:
1) Technical and Commercial Coordination
• matching item requirement with supplied model • coordinating quantity and delivery expectations • ensuring product labeling and traceability records were available
2) Packing and Shipment Handling
• checking physical packing condition • ensuring safe handling for transport • preparing and monitoring dispatch stage communication
3) Client Communication and Follow Up
• timely responses during order execution • after delivery support • issue escalation support when needed
4) Warranty Claim Coordination and Overseas Return Process
In December 2025, the client reported a burning issue involving one set (3 pieces) and raised a warranty claim.
Our team then coordinated the full process:
• claim communication and document collection • export of the affected units to our overseas partner (Germany channel) • technical testing coordination through ABB network/service • obtaining the formal test/investigation report • submission of the report back to the client
This end to end handling was completed by our team, and the client appreciated the speed, transparency, and professional support throughout the process.
Technical Investigation and ABB Report Support
One of the strongest parts of this case was not only the supply, but the post supply technical support.
When the client reported the issue, we did not stop at basic communication. We coordinated an actual technical review and supported formal testing through our overseas partner and ABB service process.
The investigation and test documentation helped the client get a structured technical response instead of informal assumptions.
This is exactly where many suppliers fail. They can sell the item, but they cannot manage the technical follow up, warranty communication, and report submission professionally.
Our team managed the full chain.
Why This Case Matters for Industrial Buyers
This case is useful for power and utility buyers because it demonstrates more than simple trading.
It shows capability in:
• trial order conversion into repeat orders • supply reliability for protection equipment • serial number based traceability • packaging and handling discipline • warranty claim coordination • overseas technical testing support • formal report submission to client
For buyers, this reduces risk. For engineering and store teams, this saves time. For procurement teams, this creates confidence in future orders.
Outcome
The project delivered value in two stages:
Stage 1: Supply Performance
The client moved from trial basis ordering to repeat orders, with total supply reaching 9 units.
Stage 2: After Sales and Claim Handling
When a field issue appeared later, our team handled the warranty claim route, overseas return coordination, ABB technical testing support, and final report submission to the client.
The client was satisfied because the full process was handled professionally by one team without confusion.
Conclusion
This UPGDCL (Former UEL) case study shows how industrial procurement support should work in real life.
Supplying the product is only one part. The real value comes from:
• technical coordination • documentation discipline • traceability • responsive communication • after sales issue handling • formal testing and report support
That is how trust is built and repeat orders happen.
If you are a utility, EPC team, or industrial buyer looking for a supplier support team that can manage both supply and post supply coordination, this case shows how we work.
This case study is shared as a record of our past execution experience in industrial procurement, import handling, and installation coordination.
In this project, the client was Chittagong Urea Fertilizer Limited (CUFL), Bangladesh, a government entity under BCIC. The purchase order date was 03 December 2014. CUFL required a Rotork actuator assembly with UK origin.
At that time, Impro Solution Bangladesh was operating as a Rotork distributor in Bangladesh. We managed the planning, commercial coordination, import route decision, and execution support for the project.
Client Requirement
CUFL required a Rotork actuator assembly for plant use, with emphasis on:
correct specification matching
UK-origin requirement
import and commercial handling through proper channel
successful installation support
Client purchase order record (redacted/archived) dated 03 Dec 2014 for Rotork actuator assembly supply.
What We Did
Impro Solution Bangladesh handled the project through a structured approach:
planning and decision-making for supply route and execution
coordination of sourcing through Rotork India
support for UK-origin requirement
import into Bangladesh through Letter of Credit (LC)
outsourced engineer arrangement for site installation support
execution follow-up until successful installation
Site installation coordination support for actuator replacement/installation at CUFL
Supply and Import Route (Commercial Structure)
The client required UK-origin equipment. The practical supply route was managed as:
Rotork UK → Rotork India → Import to Bangladesh (LC basis)
This route helped complete the transaction in a commercially workable way while meeting the client’s requirement.
Installation Outcome
We arranged outsourced engineering support and the actuator was installed successfully at site. The client was satisfied with the project outcome.
Project Leadership
Although execution involved multiple parties, the project planning and key decisions were led by Shafiqul Mowla, Owner of Impro Solution Bangladesh.
Why This Experience Matters (Service Relevance)
This case demonstrates our real experience in:
industrial procurement planning
origin-sensitive supply handling
LC-based import execution
vendor route coordination
site execution support management
Today, we use this experience to provide service-based support only for clients, including:
risk-focused commercial and import documentation guidance

Ashuganj Power Station Company Ltd, Bangladesh issued a work order for supplying an actuator for 450 MW CCPP North on 23 July 2020. The client required a genuine AUMA actuator for a critical plant application, with full confidence on originality and correct specification.
At that time, there was an active local distribution channel in Bangladesh. During the process, a concern was raised that the client might receive a grey market product. This was a serious issue because for a power plant actuator, wrong origin or unclear source can create long term risk in reliability, warranty, and future maintenance.
We handled the case by using our own cross border capability through Impro Solutions Bangladesh and Impro Solutions UK Limited. Instead of depending only on local market statements, we built a proof based supply path and submitted supporting documents to the client. Our role included planning, source validation, commercial coordination, and execution follow up.
What we did
We arranged the actuator through our UK side and established a clear procurement trail. We submitted commercial and technical proof to assure the client that the item was original and supplied through a valid channel. The documents and evidence package included invoice level records, product details, and shipment related records. We also shared physical product photos after receipt to support visual confirmation and traceability confidence.
This helped the client move from market doubt to document based assurance.
Why this matters for USA buyers
For USA power and industrial buyers, this case is not only about one actuator. It shows a bigger capability that matters in high risk procurement:
handling authenticity challenge when channel conflict exists
proving source credibility with documents, not only words
supporting critical plant items with execution discipline
protecting the end user from uncertain supply origin risk
In many international procurements, the biggest problem is not only price. The real problem is trust, proof, and traceability. This case shows how we think and act when an item is technically important and commercially sensitive.
Outcome
The client accepted our proof and was assured on product originality. The supply was completed for Ashuganj CCPP application, and the project moved forward successfully with execution support from our side.
Behind the project, I personally led the planning and decision making as the owner of Impro Solution Bangladesh, including route decision, commercial coordination, and client assurance strategy.
What this case demonstrates
This project demonstrates our practical strength in:
power plant procurement support
original product verification
document backed assurance for end users
cross border sourcing coordination through Bangladesh and UK
This is the type of execution discipline that international buyers, EPC teams, and plant procurement managers often need when facing source doubt, brand sensitivity, and procurement risk.

Siemens transformer protection relays for Potia Substation, Chattogram
Client sector: Electrical transmission substation Location: Potia, Chattogram, Bangladesh Year: 2017 Product: Siemens SIPROTEC transformer‑protection relays (types 7SJ6225‑4EB00‑1FC1 and 7UT6125‑4EB00‑1BA0) Procurement channel: Direct import under Impro Solutions Bangladesh / Impro Solutions UK Ltd
Project context and challenges
The Potia substation project required transformer‑protection relays urgently. The utility issued a request for quotation with a very tight delivery schedule and insisted that the goods come from Siemens’ German factory. At the time there was no local stock, so our sourcing team needed to find a reliable supply within days. Delays would have left the substation without protection equipment and risked grid instability.
Our approach
Rapid sourcing: Within hours of receiving the RFQ we contacted Siemens’ German sales office and confirmed availability of the 7SJ6225 and 7UT6125 relay models. Because these devices are made‑to‑order, we arranged to purchase units that were already in the production queue.
On‑site inspection: To ensure quality and compliance we travelled to Germany, inspected the relays at the factory and witnessed factory acceptance tests. Photos from our visit show the front panel of the SIPROTEC relays with their menu controls and indicator LEDs and the rear of the units with labels and connection terminals.
Customs and logistics: We handled all export documentation and coordinated with freight forwarders to ship the equipment by air. Our understanding of Bangladesh import regulations allowed us to clear customs quickly and avoid demurrage.
Outcome
The relays arrived at the Potia substation ahead of schedule. The client confirmed that the units were genuine Siemens products and matched the specified types. By managing the entire procurement process—from sourcing to on‑site inspection and customs clearance—we met the client’s urgent timeline and prevented costly project delays.
Lessons learned
Early engagement with the manufacturer can reveal stock or near‑finished units that shorten lead times.
On‑site inspection builds trust and ensures that products meet specifications.
Knowledge of local import procedures is critical for fast delivery on projects where timing is vital.
