7. TESTS
 
7.1 - Routine tests - according to IEC 60076:
7.1.1 - Measurement of winding resistance.
7.1.2 - M35-500 kV Seriel• Oil Immersed Power Transformer has .pt,mlzed design using advance techn.the resistance t. sh.rt circuit capacity. Advance design are ore used f.,elect,.magnetic calcion and de.,gn of transformer. while 3·.2·0 CAD softwares for design ensure suffic,ent sa'ety margin during short circuit peri.d This is based on in depth th!.retical and experimental studies .n magnetic, thermal, mechar,,cat strength and sh." circuit strength. To ensure reliability .t the transformer the insulation are decided based .n ca easurement of voltage ratio and check of voltage vector relationship.
7.1.3 - Measurement of impedance voltage.
7.1.4 - Measurement of load loss.
7.1.5 - Measurement of no load loss and no load current.
7.1.6 - Measurement of insulation resistance.
7.1.7- Routine dielectric tests (according to IEC 60076):
Induced overvoltage withstand test.
Separate source power frequency voltage withstand test.
7.1.8 - Tests on bushings - and OLTC:
-The routine tests on the bushings and on the OLTC will be done by the respective manufacturers.
