    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.

  • 13 very important type tests of a low voltage switchgear

    Type Tests Defined in IEC 61439Type TestsAdditional Type TestsCertification of distribution assemblies is defined by international standard IEC 61439-1. This standard provides common rules that are recognized worldwide. Compliance with the standard is certified, depending on the country or market, by a declaration of the panel builder, the design office, the installer or the user. Just to mention before going into test, that low voltage switchgear and controlgear assemblies (Un ≤ 1000 V AC) may be used at the origin of an electrical installation with: 1. Low Voltage Main switchboard (transformer area) 2. Low Voltage Main Distribution Board (technical area) and 3. Sub Distribution boards Seven type tests are carried out officially on low voltage assemblies representative of the usual wiring configurations and equipment layouts. These assemblies are called ‘standard assemblies’. By definition, standard assemblies only contain layouts that have undergone type tests. Table of contents: They cover the following checks for type tests: 1. Type tests:...
