MACROTESTG3 HT Instruments HiPot

The MACROTESTG3 is a HiPot from HT Instruments. HiPot, or high potential, is a class of electronic test equipment used to verify electrical insulation. Engineers use HiPot-testing instruments on cables, wires, circuit boards, appliances, electric motors, and transformers. As a product ages, its insulation may break down and result in current flow leakage. HiPot testers keep engineers safe from current leakages by detecting gaps and defects in the electronic device. Dielectric Testers, Insulation Testers, and Megohmmeters are similar to HiPot testers. Popular manufacturers include Biddle, Megger, Fluke, Associated Research, Quadtech, Instek, and Slaughter.

The MACROTEST G3 is an innovative multifunction installation tester capable of carrying out safety tests on civil and industrial electric systems in compliance with IEC/EN61557-1. Its resistive TFT color touch-screen display, its icon menu, its help-on-line and its user-friendly development make the instrument extremely intuitive even for unskilled users. Its numberless features grant the user a wide range of applications in the world of measurements.

The multifunction installation tester MACROTEST G3 allows saving all measures into an internal memory so transferring the saved data to a PC by means of USB (provided as standard) or built in Wi-Fi interfaces with an iOS and Android smartphones or tablets . The software supplied among standard accessories allows printing testing reports.

The multifunction installation tester MACROTESTG3 also drives the optional accessory IMP57 to carry out high resolution (0.1mOhm) loop/line impedance measurements with prospective short-circuit current calculation. This allows accurate measurements even close to power stations enabling the user to correctly size the protection devices in any system.
