Megger LTW325-2 Wire Non-tripping Loop Impedance Testers

The Megger LTW325 Loop Impedance Tester is a robust and reliable tool designed for quick and efficient verification of loop impedance in electrical circuits, ensuring that testing can be performed without disconnecting the electrical supply. This advanced tester is capable of full two-wire loop testing and is engineered not to trip RCDs rated at 30mA or higher, making it an indispensable device for electricians and technicians working in various settings.

Key to the LTW325’s functionality is its ability to perform loop testing using just two leads. It offers versatile connection options, including phase to earth, phase to neutral, or phase to phase, enhancing its usability across different types of electrical systems. This flexibility makes it suitable for a wide array of applications, from residential troubleshooting to complex industrial systems.

Megger LTW325-2 features

One of the standout features of the Megger LTW325 is its integrated no-trip loop test function. This feature ensures that the device will not inadvertently trip any RCDs rated ≥30mA during testing. This is particularly beneficial in environments where continuous power supply is critical, and any interruption could lead to downtime or other operational issues.

Additionally, the LTW325 includes a separate high current loop test option, which can be utilized in systems without an RCD. This allows for comprehensive testing of the electrical circuit’s integrity, regardless of the protective devices installed.

Accuracy is paramount in electrical testing, and the LTW325 addresses this with an integrated electrical noise detection filter. This filter is specifically designed to detect and mitigate the effects of heavy electrical noise, which can adversely affect the accuracy of test results. By filtering out such disturbances, the LTW325 ensures that the measurements obtained are both reliable and accurate, providing a clear assessment of the electrical circuit’s safety and functionality.
