BLUE JAY ZJJ-4SA
The BLUE JAY ZJJ-4SA is a DC insulation monitoring relay that uses a fully static circuit and has a highly sensitive grounding resistance monitoring and display circuit. It can directly display the grounding resistance value, which solves the confusion caused by the old relays that have no display or can only display the grounding current.
The ZJJ-4SA is widely used in DC speed regulating motors, solar power generation and other fields. It can be used to monitor the insulation of electrical equipment, supporting use of power transformers, generators, and motors. It can also be used in remote monitoring systems for real-time monitoring of insulation conditions, and in substations, power plants, transmission lines, and distribution lines.
