Low Voltage Switchgear involves switches like power circuits, relays etc. It is important that a periodic inspection and test carried out at least every 1-2 years and 2-6 months when new equipment is installed. In this section we discuss about some guidelines for inspection and maintenance of low voltage switch gear 1)       On energized equipment                              Three things you must do a)       Listen for popping, spitting or cracking sound produced by the electrical discharges-also humming and vibrations produced by the resonance b)       Look for corona halos c)       Check for ozone – ozone is produced by corona or overheating of organic materials 2)       On de-energized equipment’s Three things you must do a)       Check and co...
