Testing

UTTAM BHARAT is committed to manufacturing top-quality pad-mounted distribution transformers. Our dedication to excellence is evident in the rigorous testing we conduct to ensure compliance with the latest ANSI/IEEE standards (C57.12.00, ANSI C57.12.90, and ANSI C57.12.29).

Every transformer we produce is subjected to a comprehensive set of factory tests to verify its engineering integrity and ability to perform under rated load and real-world operational conditions. Each pad-mounted transformer must pass the following routine tests:

Polarity and Phase-Relation Test
Turns Ratio Test
Full Wave Impulse Test
Applied Voltage Test of HV and LV Winding
Induced Overvoltage Test
No-Load Loss and Excitation Current Test
Resistance Measurements
Load Loss and Impedance Voltage Test
Tank Leak Test
Wire Probe Test
Audible Sound Level Test
Temperature Rise Test

Our testing equipment is regularly calibrated by skilled technicians, and all calibration records are meticulously maintained in accordance with our quality system procedures. These procedures are annually audited by a third party to ensure compliance with ISO standards.

Quality Assurance

Compliance with IEEE Standards

Our products undergo rigorous electrical testing in full compliance with IEEE standards, ensuring exceptional performance and safety.

Certified Excellence

UTTAM adheres to the highest quality management standards as evidenced by our ISO 9001 certification.

Comprehensive Testing Protocols

In addition to standard tests, we perform a variety of supplementary tests to enhance control and ensure reliability, including:

Core loop loss and exciting current measurements.
Verification of core-coil assembly ratio and polarity.
Evaluation of oil properties for optimal performance.
Triple-tiered leak tests to guarantee complete integrity and durability.
