Loop Impedance Testers

What is loop testing?
Loop testing is a quick, convenient and highly specific method of evaluating an electrical circuit for its ability to engage protective devices (circuit breakers, fuses, Ground-fault circuit interrupter).
There are 5 test methods:
• two-wire high-current
• two-wire no-trip with dc injection
• three-wire no-trip
• two-wire no-trip
• four-wire grid impedance testing

The main reason for earth loop impedance testing, is to verify that if a fault occurs in an electrical installation, sufficient current will flow to operate the fuse or circuit breaker protecting the faulty circuit within a predetermined time. The objective is to make sure that the circuit is disconnected fast enough to prevent overheating and possibly a fire.
