Megger LTW335-2 WIRE NON-TRIPPING LOOP IMPEDANCE TESTERS 

The new Megger LTW335 Loop Impedance Tester reduces testing time and removes the possibility of making a mistaken connection. It may check the loop impedance of a live electrical circuit without disconnecting the power source by using two-wire earth loop testers. In situations where the neutral is absent or inaccessible like light switches and systems with 110V center-tapped supply, the LTW335’s trustworthy two-wire testing provides a huge advantage.

With any supply between 50V and 440V AC, this loop impedance tester has all the features required for two-wire, non-trip loop testing. The two-wire loop testing solution, like the rest of the LTW300 series, is guaranteed not to trip 30mA RCDs.

Megger Loop Impedance Testers isolate the test signal from the supply’s fundamental frequency by utilizing the most recent advancements in digital processing techniques. This means that non-trip testing can be carried out without DC injection because the Megger LTW335 Loop Impedance Tester automatically averages a large number of results over the course of the test.

Standard features included with every Megger Loop Tester include PFC calculations. These durable, user-friendly tools were created in response to the needs of electrical contractors operating in the competitive and demanding market of today, following a thorough process of customer research.
