Our Neutral Grounding Resistors Have Successfully Passed New Type Tests!
We had the type tests of our NEUTRAL GROUNDING RESISTORS performed at the VEIKI-VNL Accredited Laboratory, one of the leading test centers in Europe, located in Hungary. While all of our products passed the tests, it was confirmed that our products were produced in accordance with the current TEİAŞ specifications.
Our tests were applied to Neutral Grounding Resistance of 36/√3 kV 1000 A, 20 ohms for 10 seconds.
