GIS measurement tools for HV MV

Figure 1 – Example of primary medium voltage switchgear – UniGear ZVC feeder unit. With the release of the IEC 62271-200 standard, new definitions and classifications of Medium Voltage switchgear have been introduced.. One of the most significant changes is that classification of switchgear into metal-enclosed, compartmented and cubicle types has been abandoned.

    No. Travel measurements are a very valuable tool in circuit breaker analysis. One of the common arguments against measuring motion on vacuum CBs is that the contact stroke is so short that you are better off measuring stroke with a pair of calipers when the breaker is in fully open position compared to fully closed position and you can verify the CB is traveling fast enough from the contact times.
