The Most Important Tests For Medium Voltage Metal-Enclosed

Insulation Resistance Measurement Test. The insulation resistance measurement test may be conducted on all types of electrical switchgear using the insulation resistance megohmmeter commonly known as the MEGGER. High-Potential (Hi-pot) Test. DC Hi-Pot Test. The DC hi-pot test is normally not made for AC electrical switchgear and therefore may be considered only when AC hi-pot cannot be performed. Power Factor Testing. The power factor testing of an insulation system is useful in finding signs of insulation deterioration. The absolute values of power factor measured have little significance. Circuit Breaker Contact Resistance Measurement Test. Stationary and moving contacts are built from alloys that are formulated to endure the stresses of electrical arcing.
