Product Description

Product Description

AIM-T500 Ground Fault Detectors Insulation Monitor for Ungrounded AC/DC System

General
The AIM-T500 insulation monitor is an instrument developed for monitoring the insulation status of IT distribution system (ungrounded system) to ground with many years of design experience in the power instrument industry.Products adopt advanced microcontroller technology, high integration, compact size, easy to install, set intelligent, digital, networking in one.It has the characteristics of wide measuring range, fast reaction speed and large leakage capacitance.At the same time, it has rich functions, such as insulation fault warning, fault alarm, event recording, interconnection and parameter free setting.IT can be used in IT distribution system of mine, glass factory, electric furnace and test equipment, metallurgy plant, chemical plant, explosion dangerous place, computer center and emergency power supply and other industrial places. IT can monitor the insulation condition of IT distribution system to the ground in real time. When insulation fault occurs, IT can give alarm in time and remind staff to check the fault.
