The Value of Current Leakage Testers

While electricity functions in predictable ways, people do not. Maintain your safety standards and ensure everyone on-site is protected from faulty wires with top-quality current leakage testers.

A current leakage test simulates the consequences of a person touching an exposed part, like a wire. The test determines whether the leaked current will remain at a safe level when it flows through their body. It acts as an important point of reference in case anyone is accidentally exposed to live electricity during their work.

Conductors are coated in insulation to shield individuals from the current running through them. However, since the voltage is sometimes an unknown factor, current leakage testers are the most practical solution to protect personnel.

In other cases, high levels of leakage may occur in circuits where electronic equipment includes filters, causing voltages that disrupt the standard operation of equipment. High-voltage testers and fault locators provide essential information about the equipment and pinpoint areas of concern.
