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 testingThe 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.
