This insulation tester 307A is intended primarily for periodic testing of
industrial motors, transformers, electrical wiring, and cable insulation for
signs of deterioration. Low readings may indicate impending failure
allowing for permit replacement of suspect component during routine
maintenance rather than risking component failure. It is also useful for
safety testing of TV sets and appliances to assure no hazardous leakage
current. The voltage and resistance ratings for insulation testing are
often specified for the product to be tested.

Applications
Why Test is Necessary?
• Insulation
Every electrical apparatus and installation needs to be safe for the user and for
the equipment itself.
Electrical conductors of electricity needs to be insulated from each other, so
that they do not create electrical hazard or unnecessary consumption.
Poorly insulated circuits can create leakage current which can be dangerous
and trip your GFCI, RCCB or ELCB.
Each country regulates levels at which the insulation levels are acceptable.
Generally, Insulation resistance measurement should be done between each
conductor and the earth, and between each conductors.
• Continuity
Checking the continuity of wires, complete circuits, connections, closure of
contacts, circuit breakers, fuses, bounding resistance of connections, etc... are
all very important to ensure wire integrity.
