The Megger LTW425 Loop Impedance Tester is three phase safe and category IV 300V rated, making it suitable for use on supplies from 50V to 300V AC single phase, as well as on 440V three phase installations. The LTW425 Tester automatically averages a large number of results over the duration of the test. This enables non trip testing to be performed without DC injection, a technique which is, in any case, proving ineffective with electronic RCDs.

The LTW425 offers a high current high resolution loop test to three decimal places. This is ideal for establishing the correct Ze on an incoming supply, especially on PME installations. Results of this test can also be used to calculate higher PFC results.
