Our experienced Quality Assurance Engineers carry out stage inspection during the manufacturing process. All instruments used for testing are of Precision Grade and are periodically calibrated.
All Routine tests as per IS 2026 are performed on every Transformer manufactured, before they are dispatched from our works. We are also equipped to conduct few Type tests at our works. Impulse and Dynamic Short Circuit withstand tests are carried out at CPRI/ERDA. Kindly inform us at order stage itself, in case you wish to witness routine/type tests.
Test results are stored for 5 years for analysis.
Input Materials are checked for confromation to our specifications. Wherever required, our QC Engineers visit Supplier's
factories to witness their routine test.
Our Transformers have been Type Tested in Central Power Research Institute, Bangalore (CRPI) and ERDA Vadodara.
We have in-house facilities for performing all the routine tests and some of the Type Tests as per Indian and International Standards.
Our Manufacturing practices are certified by EURO VERITAS under ISO 9001:2008.
Routine & Type Tests:
Transformers and Reactors are tested for following Routine Tests wherever applicable. Type Tests are carried out in Standard Laboratories on representative ratings and Certificates are available:
Turns Ratio Test Polarity Test Terminal Markings Overall Dimensions Load and No-Load Losses Measurement Impedance MeasurementC* Insulation Resistance Test
Power Frequency High Voltage Withstand Test Induced Over Voltage withstand Test Oil Break down Voltage Test Pressure Test for Oil Cooled Transformers Temperature Rise Test (Proto Types only) Lightning Impulse Withstand (Type test) Short Circuit Dynamic Withstand (Type Test)
Computerised design and testing methods streamline the manufacturing process and cut down on lead time make our products cost effective to our customers.
INDCOIL transformers incorporate most modern engineering concepts and high quality materials, processed under expert supervision and rigid quality control.
INDCOIL covers a full range of Current Transformers both for metering and protection manufactured conforming to International Standards.
