Insulation Testers (500V/1000W)

Insulation resistance testers provide evidence to show the condition of the insulation in a building or electrical equipment. Rapid deterioration of insulation and poor insulation resistance are found via pressuring the insulation. Bad insulation resistance in electrical equipment and systems could lead to an electric shock hazard or to fires and product failure.

Insulation resistance testing is often referred to in the industry as ‘meggering’ the word originating from the ‘Megger brand’. Single phase equipment and systems will usually have a voltage of 250/500 volts DC applied between earth and live conductors. 3 Phase is normally tested at 1000V DC.

Sonel insulation resistance meters are packed with advanced features, many with a memory function, making analysing and fault finding easy.
