Ior detection method Insulation condition monitoring device with earth leakage direction function
Hikari Shoko Co., Ltd.
About This Product
The Ior detection method is adopted for insulation condition monitoring and earth leakage monitoring. Based on the zero-sequence current detected by ZCT and the voltage to ground detected between the L and E terminals, calculations are performed according to the set electrical method, and the capacity is calculated. It operates by detecting only the resistance component (active component) current excluding the reactive component (reactive component).
■Features
・This is an insulation condition monitoring device using Ior detection method. Constantly monitors the insulation condition of the electrical circuit.
・The earth leakage monitoring section has a directional function to prevent accidents.
