Why Insulation Test Is necessary?

• A. Insulation:
• 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.
• B. Continuity
• Checking the continuity of wires, complete circuits, connections, closure of contacts, circuit breakers, fuses, bounding resistance of connections, etc. are all very important.
