Current leakage testers are devices that are used to measure the amount of current that passes through a ground conductor. These devices can be used both during normal and single-fault conditions to determine whether electrical devices pose a shock hazard.

Salient Features & Uses

• The tester consists of a measuring device or probe that gets connected to a voltmeter that displays root mean square values.
• The tester also includes a circuit featuring specific frequency and resistance.
• Available as manual, semi-automatic and automatic types.
• Common testers include an RS232 serial bus or a parallel port designed for connecting to a printer.
• There are some leakage testers, which consists of a general-purpose interface bus and are designed to connect to computers, peripherals, and laboratory instruments.
• These devices differ in terms of current leakage range, communications, resistance range and special features.
• The leakage testers meet the requirements of various national and international standard organizations.
• Provided with a rapid cut off system to protect the device from high voltage or current.
• Provided with front panel lockouts that prevent any damage to the instrument during testing.

Applications

The leakage tester finds application in the following areas:

• Medical Devices
• Laboratory Instruments
• Computer Peripherals
• Testing Devices
