Megger LTW325 Loop Impedance Tester
Megger LTW325 Loop Impedance Tester verifies the loop impedance of a live electrical circuit.
The Megger LTW325 Loop Impedance Tester is a two-wire plus maxZ + (R1+R2) earth loop tester which verifies the loop impedance of a live electrical circuit, i.e. without the need to disconnect the electrical supply.
The Megger LTW325 Loop Impedance Tester uses a 2-wire loop testing solution that does not trip 30 mA RCDs.
The Megger LTW325 Loop Impedance Tester will operate on a wide range of voltages from 50 V AC to 300 V AC single phase supplies and up to 440V AC on 3 phase installations. This includes centre tapped 110 V AC circuits, with 55 V phase to earth.
A loop test is performed with only 2 test leads. This can be either:
- Phase to Earth
- Phase to Neutral
- Phase to Phase
Testing is simple, as there is no need for a 3rd wire to be connected, which can cause confusion when trying to identify which part of the circuit is being tested.
Megger LTW325 Loop Impedance Tester features:
- 2 Wire Non-tripping loop testing
- 2 Wire fast test (high current)
- 50 V to 440 V applications
