Inspection/Testing |
All Transformers
are subjected to all routine tests in our sophisticated
laboratory in factory confirming to latest national
and international standard specifications. Test
are intended for use for the basic validation
of design and the basis for performance, safety,
and reliability of the transformers.
Runthala is equipped with adequate
digital readout measuring devices wherever required
and the digital sampling techniques with computer
calculation. Precision digital meters such as
digital power analyzer, WT-130 of Yokogawa of
Japan make are used for measuring load losses,
impedance Voltage, No load losses, and no load
currents. |

All
Transformers are subjected to
all routine test.
This includes, following tests.
• insulation Resistance Test
• Resistance measurement of winding
• Turns Ratio Test
• Polarity and phase relationship test
• No Load tosses measurement
• Excitation current measurement
• Impedance voltage test
• Load Loss measurement
• Insulation oil Test
• Dielectric test
• Leakage Test of transformer tank |

| Type
Tests : Type tests are made to
prove to withstand all irregularities in transmission/distribution
line. Runthala have in house facility
to undergo temperature rise and impulse test Conforming
to meet latest national and international standard.
Other tests such as short circuit withstand tests (Dynamic
& Thermal) are conducted at an independent govt.
recognized testing laboratory at Central Power Research
Institute, Bhopal/Banglore and ERDA, Baroda, INDIA.
Type test are special optional tests. These tests are
carried out at an additional fees, which is to be borne
by the customer.
• Impulse Voltage Test
• Temperature rise Test
• Short Circuit Test
