Megger LTW315-2 Wire Non-tripping Loop Impedance Testers

The Megger LTW315 Loop Impedance Tester represents a significant advancement in electrical testing technology, designed specifically to cater to the needs of modern electrical contractors. This innovative tester is part of the LTW300 series and is engineered to ensure accurate, efficient, and non-tripping loop impedance testing using only two wires. The LTW315 is an ideal tool for verifying the loop impedance of live electrical circuits without the necessity of disconnecting the power supply, making it a crucial time-saver in various testing scenarios.

Megger LTW315-2 features:

One of the standout features of the LTW315 is its ability to perform dependable two-wire testing, even in situations where the neutral conductor is missing or difficult to access. This capability is particularly beneficial for testing in complex environments such as light switches and systems utilizing 110V center-tapped supplies. The tester is equipped to handle all supplies ranging from 110V to 280V AC and is carefully designed to avoid tripping 30mA RCDs during testing.

Utilizing cutting-edge digital processing techniques, the Megger LTW315 distinguishes the test signal from the fundamental frequency of the supply. This sophisticated approach allows the device to automatically average numerous test results over the test duration. As a result, it facilitates non-trip testing without the need for DC injection, enhancing both the safety and efficiency of the testing process. Additionally, the LTW315 includes a Prospective Fault Current (PFC) calculation feature, which is a standard offering across all Megger Loop Testers.

The LTW315 Loop Impedance Tester is not only effective but also user-friendly. It is constructed to withstand the rigors of regular use in a professional environment, demonstrating both durability and ease of operation. Developed after extensive customer research, the LTW315 meets the specific demands of electrical contractors who require reliable, precise tools that can keep pace with the competitive and challenging conditions of today’s market.
