GW Instek GPT-9904 — Electrical Safety Tester
The GW Instek GPT-9904 is an electrical safety tester (hipot) in the GPT-9900 series, designed to perform withstand testing and measurements related to dielectric strength, insulation, and ground bonding. The device covers AC and DC withstand tests, insulation resistance measurement, and ground bond tests, and comes with standard communication and remote control options.
What it Does
The GPT-9904 can generate AC and DC test voltages for testing insulation strength and leakage current, as well as measuring insulation resistance and ground bond resistance. The device includes features such as window comparator, ARC detection, ramp and sweep functions, and a built-in timer for precise test sequences. Front and rear connections support both local and remote control.
