High Voltage Current Transformers Test Setup Completed in Indonesia

High Voltage & extra High Voltage Switchgear manufacturing companies needs High Voltage Current Transformers and High Voltage – Voltage Transformers  test set-up for in-process testing & final testing.

KAT Controls has been working & supplying this test set-up for HV switchgear manufacturing companies, locally and globally, for the last 25 years. 

KAT Controls has complete Technical know-how & experience of the test requirement as per International quality standard IEC 61869 – part 1 & 5 & Indian standard IS-16227.

All required test as per International/ National quality standard on HVCT, ranging from 72.5kV – 800 kV, Primary – Up to 10000 A & secondary- 1A/5A (with 1/5 A burden selection), can be performed.

Routine Test
