Test Facilities

All transformers are tested in our sophisticated laboratory for the following routine tests conforming to National and International Specifications.

• Voltage Ratio.
• Winding resistance.
• Impedance Voltage.
• No load and Load Losses.
• No load Current.
• Dielectric tests.

	Major Test Facilities

In addition to the normal routine test facilities, the following major type test facilities are available in-house for the type testing the transformers to all major international standards.
• Switching and lightning impulse test system.
• Partial discharge and radio interference measurement facilities.
• Noise level measurement setup.
• Temperature rise test plant.
• Dissolved gas analyzer (DGA) for oil.
• Harmonic Measurement and Analysis.
• Linearity Test Set For High Voltage Reactors.
• Vibration test plant.
• SFRA test.
• Routine Test As Per BS / IEC / ANSI.
The transformer designs are proven for dead short circuits by tests conducted at the independent, accredited short circuit labs.

We can thus perform any Type Tests as under, if required to ascertain standard conformance:

• Measurement of Harmonics of No Load Current.
• Temperature Rise test along with Dissolved Gas In Oil Analysis.
• Measurement of Zero Sequence Impedance.
• Lightning and switching Impulse Test.
• Partial Discharge and Radio Interference Voltage Test.
• Measurement of Acoustic Noise.
