PKV/M7 Advanced HV circuit breaker analyzer

PKV/M7 is an advanced HV circuit breaker analyzer that provides high precision measurements of time, travel, and speed characteristics of moving parts.

Advanced HV circuit breaker analyzer PKV/M7 review

PKV/М7 is designed for measuring characteristics of SF6, oil, magnetic-type and vacuum high-voltage circuit breaker of all types and manufactures (such as ABB, AREVA, ALSTOM, SIEMENS etc.), and of isolators and short-circuiting devices. Additionally, PKV / M7 allows you to register instantaneous values ​​of currents and voltages of control  electromagnets.

What will "digital energy" choose: automation or portable diagnostics?

We offer to consider the features of diagnostics using automatic monitoring systems (transducers) in real operating conditions and using specialized portable devices produced by SKB EP LLC, which require disconnection of voltage coming to the measured object, by the example of a high-voltage circuit breaker.

Comparison of instruments for control of high-voltage circuit breakers produced by SKB EP

Different methods are used for assessing the state of HV circuit breakers, whereas special instruments, such as PKV/M6N, PKV/M7, and PKV/U3 considerably facilitate and accelerate the diagnosis.  These instruments allow recording the time and speed characteristics of HV circuit breakers, and graphs of traverse move.
