HKJY - E DC Insulation Detecting Device
Application Scenarios:Used in direct current application field,such as photovoltaic generation area,electric mobile recharging pile,etc.
PRODUCT OVERVIEW
Mainly used to monitor the insulation status of the IT system (ungrounded system) to the ground,it can detect the insulation resistance value of the positive and negative poles of the DC floating system to the ground.and to alarm in time when the system has an insulation fault to remind the electrical maintenance personnel to troubleshoot the fault.
