Why Insulation Test Is necessary?
1. Every electrical apparatus and installation need to be safe for the user and for the equipment itself.
2. Electrical conductors of electricity need to be insulated from each other so that they do not create electrical hazard or unnecesary consumption.
3. Badly insulated circuits can create leakage current which can be dangerous and trip your GFCI, RCCB or ELCB.
4. Each Country regulate those levels at which the insulation ia aceptable.
Generally, insulation resistance measurements are done between each conductor and the earth, and between each conductors.
Checking the continuity of wires, complete circuits, connections, closure of contacts, circuit breakers, fuses, bounding resistance of connections, etc. are all very important.
