AIM-D100-TThe series of DC insulation monitoring instruments can be applied in10~1000VIn the DC system, it is used for online monitoring of the positive and negative pole to ground insulation resistance of the DC ungrounded system. When the insulation resistance is lower than the set value, a warning or alarm signal is issued. The product is based on the principle of unbalanced bridge, which avoids the problem of inability to detect insulation resistance when the balanced bridge has grounding faults in both positive and negative poles. The product can be applied to power generation manufacturers, DC screens in substations, electric vehicle charging devicesUPSDC systems such as power supply systems, photovoltaic DC systems, energy storage systems, and other DC power grids.
