  • What is HIPOT Testing (Dielectric Strength Test)?

    Mar 30, 2021 · Hi-Pot test is a contraction for high potential HV testing. Hipot Test is short name of high potential (high voltage) Test and it is also known as Dielectric Withstand Test. A hipot test checks for “good isolation.” Hipot test makes surety of no current will flow from one point to another point.

  • Switchgear - Wikipedia

    High-voltage switchgear was invented at the end of the 19th century for operating motors and other electric machines. The technology has been improved over time and can now be used with voltages up to 1,100 kV. Typically, switchgear in substations are located on both the high- and low-voltage sides of large power transformers.

  • 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.
