Megger LTW315 Loop Impedance Tester Details

Megger's LTW315 is a two-wire earth loop tester that directly measure loop impedance of live electrical circuits without the need to disconnect.

Portable, reliable and robust enough to be used in demanding environments, the LTW315 can perform loop testing on phase to earth, phase to neutral and phase-to-phase. It's also guaranteed not to trip RCDs at a working current of more than 30mA thanks to its built-in non-trip loop testing function and suitable for use with 3 phase and single phase equipment.

To ensure accurate results are always generated the LTW315 users advanced noise detection to continously monitor the supply and filters out the effects of electrical noise (which can cause incorrect results if left unchecked). PFC can also be displayed on the instrument up to 20kA.
