General
With the development of industry, many electrical equipment and factory equipment are powered by DC systems, and the positive and negative poles of the DC system are not grounded. For ungrounded (IT) power distribution systems, insulation resistance monitoring should be performed to ensure the safe operation of the power supply system .
AIM-D200-CAI DC insulation monitor can be used in 100 ~ 1000V DC systems for online monitoring of the insulation resistance of the positive and negative poles of an ungrounded DC system. When the insulation resistance is lower than the set value, it will send warning or alarm signal.
The product is based on the unbalanced bridge principle, which avoids the problem that the balanced bridge cannot detect the insulation resistance when ground fault at both the positive and negative poles.
The product is designed for insulation monitoring of electric vehicle charging piles in the range of 100~1000V , and can also be used in DC systems such as energy storage DC, DC panels in substations, UPS power supply systems, photovoltaic DC systems and other DC power grids.
