Megger LTW335-2 Wire Non-tripping Loop Impedance Testers

The Megger LTW335 Loop Impedance Tester is a cutting-edge tool designed to enhance the efficiency and accuracy of electrical testing, particularly suited for environments where quick and reliable loop impedance measurements are critical. This tester is part of the LTW300 series and is renowned for its ability to conduct two-wire, non-trip loop testing across a wide voltage range from 50V to 440V AC without the need to disconnect the power supply.

Megger LTW335-2 features

A standout feature of the LTW335 is its dependable two-wire testing capability, which is particularly beneficial in scenarios where the neutral is absent or hard to access, such as with light switches or systems utilizing a 110V center-tapped supply. This feature ensures that the LTW335 can perform tests safely and effectively, reducing the risk of incorrect connections and the potential for tripping 30mA RCDs. Such reliability is crucial for maintaining system integrity and operational continuity during inspections.

Utilizing the latest in digital processing technology, the Megger LTW335 separates the test signal from the fundamental frequency of the supply. This advanced technique allows for non-trip testing without the need for DC injection, enhancing both safety and convenience. By automatically averaging numerous results throughout the testing period, the LTW335 ensures accurate measurements even in complex and noise-prone electrical environments.

The LTW335 also comes equipped with standard features such as Prospective Fault Current (PFC) calculations, adding another layer of diagnostic capability. These features make the LTW335 not only a powerful tool for detecting potential issues but also for planning and verifying electrical system capacity and safety compliance.

Designed with the needs of today’s electrical contractors in mind, the Megger LTW335 is built to withstand the rigors of frequent use in a competitive market. Its robust construction and user-friendly interface make it an essential tool for anyone in the field of electrical testing and maintenance. The LTW335 is especially valued for its ability to streamline testing processes, reduce testing time, and eliminate common testing errors, thereby supporting electrical contractors in delivering safe and efficient service.
