Extech 380396 5kV High Voltage Insulation Tester

Extech 380396 5kV High Voltage Insulation Tester

The Extech 380396 5kV High Voltage Insulation Tester is a precision instrument designed to assess how safe and reliable electrical insulation in systems and components is. It is used by professionals in electrical maintenance, quality assurance, and troubleshooting, featuring a range of test voltages from 500V to 5000V which makes it adaptable of different types of electrical equipment.

Finding small electrical current leaks is easy thanks to its insulation resistance measurement of up to 60GΩ. The Polarisation Index (PI) measurement gives users insight into insulation quality over time and also aids with identifying potential deterioration. Plus, the Dielectric Absorption Ratio (DAR) measurement analyses how insulation resistance improves within a short period, making it effective with identifying problems like moisture intrusion or insulation damage.

The Extech 380396 includes a 1 to 15-minute timer function for insulation resistance (IR) tests, allowing the user to set automatic test durations. Besides insulation testing, it can also measure resistance in wires and circuits.

It includes a 6000 count display with bargraph, which provides clear and easy-to-read readings, even in low-light conditions. The output voltage and discharge voltage indicators keeps the user informed about active voltage levels, while the auto-discharge function enhances safety by releasing any remaining charge post-test. Additionally, the voltage output warns users of any remaining voltage, reducing accidental shocks.

The Extech 380396 features an auto power-off function to conserve power and extend the battery life, along with a battery check indicator to notify the user on when a replacement is needed. It comes complete with test leads, 8 C batteries, a 220V AC adaptor, a heavy-duty carrying case, and a user manual.
