Megger LTW425 Loop Impedance Tester
The new Megger LTW425 Loop Impedance Tester is a time saving loop tester that eliminates the risk of incorrect connections It uses two wire earth loop testers to verify the loop impedance of a live electrical circuit without the need to disconnect the electrical supply. The dependable two wire testing of the LTW425 is a major benefit in applications where the neutral is missing or inaccessible, such as light switches and systems with 110V centre-tapped supplies. This loop impedance tester provides all of the facilities necessary for two wire, non-trip loop testing on all supplies between 50V and 440V AC. As with all of the LTW300 series, the two wire loop testing solution is guaranteed not to trip 30mA RCDs.
Megger Loop Impedance Testers use the latest digital processing techniques to separate the test signal from the fundamental frequency of the supply. This means the Megger LTW425 Loop Impedance Tester automatically averages a large number of results over the duration of the test, enabling non trip testing to be performed without DC injection. PFC calculation is provided as standard with all Megger Loop Testers. These tough, easy-to-use instruments have been developed, after extensive customer research, specifically to address the needs of electrical contractors working in today's demanding and competitive market conditions.
The LTW425 offers a high current, high resolution loop test to three decimal places. This is ideal for the correct Ze on a supply, particularly on PME installations and allows for a greater accuracy of results.
