Practical trainings in the Republic of Buryatia, Russia

15 august 2019

In the beginning of August, 2019 SKB EP specialists visited the Republic of Buryatia, Russia to carry out several tests on high-voltage equipment. To carry out these measurements our specialists used MIKO-9(A) milliohmmeter, MIKO-21 and MIKO-10 microohmmeters, PKR-2M OLTC analyzer and PKV/M7 HV circuit breaker analyzer.

Our specialists measured resistance of the three-phase three-winding voltage transformer 10 000 110/35/10 with MIKO-9(A) milliohmmeter. During the measurement process they found a circuit break on the A phase. That statement was confirmed with the usage of PKR-2M OLTC analyzer.

Later, on the territory of the thermal power station SKB EP specialists explained how to work with PKV/M7 on the generator high-voltage circuit breaker MGG 6 kV. Experts measured circuit breaker contacts response time and also took time and travel characteristics of the contacts on B phase. Our specialists represented how to measure transient contact resistance of the contacts at all phases using the MIKO-21 microohmmeter.

Seminar participants noted practical convenience and functionality of SKB EP instruments. This approval is confirmed by further cooperation and equipping electrical teams with the modern diagnostics instruments.
