Comparison of SKB EP high-voltage circuit breaker analyzers

Various methods are used to assess the condition of high-voltage circuit breaker, but the most convenient way of circuit breaker diagnostic is the use of specially designed instruments such as PKV/M15, PKV/M7 и PKV/U3.0 . 

PKV group instruments application significally reduces the time of the complete diagnostic with a considerable increase in its quality and allows you to avoid the necessity of major maintenance.
