PKV/M7 testing on vacuum circuit breaker ABB VD4/P

In order to keep up with the times and to meet all the current industry requirements, SKB EP specialists monitor the information about new high-voltage circuit breakers appearance, expand the scope of the devices, carry out testings and, if it is necessary, modify fastening devices or test cables. As a result, users can easily diagnose their objects with SKB EP instruments, including those objects that just entered the market.

Recently, PKV/M7 circuit breaker analyzer was tested on an ABB VD4/P vacuum circuit breaker at the Irkutsk HPP. HPP employees for a long time have been using instruments manufactured by SKB EP, including MIKO-2.3 micromillikiloohmmeter, PKV/M7 circuit breaker analyzer and others.

SKB EP instruments hadn’t been previously tested on this type of circuit breakers, but during the ABB VD4/P vacuum circuit breaker diagnostics specialists didn’t have any difficulties. The testing was successful, and parameters of time, travel and speed were measured with the help of PKV/M7.

PKV/M7 is the flagship of the SKB EP devices designed for high-voltage circuit breakers diagnostics. It’s designed to monitor the technical condition of high-voltage circuit breakers up to 4 breaks, and it’s the most modern device of the PKV group.

The diagnostic results are displayed in a table with measured and recalculated parameters for each cycle operation. In addition to these tables, it is possible to receive more detailed information about the circuit breaker state from the registered graphs that you can work with using cursors and scale operation.
