Transformer Testing

Transformer Testing Service in Bangladesh

In Bangladesh, the power and energy sector plays a crucial role in driving industrial growth and ensuring reliable electricity supply. Among the many components in this ecosystem, transformers are the heart of power distribution networks. To maintain their efficiency, safety, and performance, Transformer Testing Service in Bangladesh has become an essential part of modern electrical maintenance and quality assurance.

At Pico Labs Ltd., we specialize in providing advanced Electrical Equipment Calibration and Transformer Testing Services to ensure reliable power delivery, system stability, and reduced downtime for industries and utilities across Bangladesh.

What is Transformer Testing?

Transformer testing is the process of examining a transformer’s performance, insulation, efficiency, and overall condition through specialized diagnostic tests. The goal is to ensure that the transformer is functioning correctly and safely, meeting both manufacturer and international standards.

Transformers are critical electrical devices that transfer power between circuits at different voltage levels. Even a minor fault can lead to significant losses or system failure. That’s why routine transformer testing helps identify potential issues early, ensuring uninterrupted operation and extending equipment life.

Importance of Transformer Testing Service in Bangladesh

As Bangladesh continues to develop rapidly in the power and industrial sectors, maintaining electrical reliability has become a national priority. Transformers operate continuously under various environmental and electrical stresses. Over time, these factors can cause insulation degradation, overheating, or moisture intrusion.

Here’s why Transformer Testing Service in Bangladesh is essential:

1. Ensures Electrical Safety:
   Regular testing detects insulation breakdowns or partial discharges that could lead to electrical accidents or fire hazards.

2. Improves Equipment Reliability:
   Testing helps identify hidden defects before they escalate, ensuring steady power delivery and equipment reliability.

3. Reduces Downtime:
   Preventive maintenance through transformer testing minimizes unexpected breakdowns, saving industries from costly downtime.

4. Compliance with Standards:
   Testing ensures compliance with Bangladesh Power Development Board (BPDB) and international IEC/IEEE standards.

5. Extends Transformer Life:
   Proper testing and timely maintenance can extend transformer service life by several years, improving return on investment.

Types of Transformer Tests

At Pico Labs Ltd., we perform a wide range of transformer tests, both in the laboratory and on-site. These include electrical, mechanical, and diagnostic tests designed to evaluate performance and detect any deterioration.

Here are some of the most common tests performed under our Transformer Testing Service in Bangladesh:

1. Insulation Resistance (IR) Test

Measures the resistance of the insulation between windings and ground. This test helps identify insulation degradation or moisture intrusion.

2. Transformer Turns Ratio (TTR) Test

Determines the ratio between the primary and secondary windings to verify proper voltage transformation and detect winding damage or connection errors.

3. Winding Resistance Test

Checks the resistance of the transformer windings to identify loose connections, open circuits, or shorted turns.

4. Power Factor or Dissipation Factor Test

Evaluates insulation health by measuring dielectric losses. A high power factor indicates insulation deterioration.

5. Oil Quality and Dissolved Gas Analysis (DGA)

Transformer oil acts as both a coolant and an insulator. Oil testing and DGA detect contamination, aging, or gas formation due to internal faults.

6. Partial Discharge (PD) Test

Identifies localized insulation breakdowns that could lead to transformer failure.

7. Impedance and Load Loss Test

Measures the voltage drop and losses under load to ensure the transformer performs efficiently.

8. Polarity and Phase Relation Test

Ensures correct phase relationships for parallel operation and safe power transfer.

These tests provide a complete health check of transformers, allowing early detection of potential faults before they cause system failure.

Transformer Testing Process by Pico Labs Ltd.

Our testing procedure follows international standards and is carried out by skilled electrical engineers and technicians. The process includes:

1. Pre-Test Inspection:
   Visual examination of the transformer for signs of oil leakage, rust, or loose connections.

2. Electrical Measurements:
   Performing electrical tests using calibrated testing instruments to measure winding resistance, insulation resistance, and ratio accuracy.

3. Oil Sampling and Laboratory Analysis:
   Transformer oil is sampled and tested for dielectric strength, moisture, acidity, and dissolved gases.

4. Data Analysis:
   All results are compared with standard reference values. Our engineers analyze deviations to identify potential issues.

5. Reporting:
   We provide a detailed report containing test results, diagnostic interpretation, and maintenance recommendations.

6. Recommendations for Maintenance:
   If any irregularities are found, we guide clients through corrective actions, such as oil filtration, insulation repair, or load adjustment.

At Pico Labs Ltd., our testing and calibration equipment is regularly verified to ensure high accuracy and reliability, giving clients confidence in our results.
