  • Short Circuit and Earth Fault Detector working principle

    Short Circuit and Earth Fault Detector

    EKL4B Short Circuit and Earth Fault Detector indicates high voltage power line short circuit fault by detecting the 3 single-phase line-currents and short circuit currents, and the grounding fault by detecting the zero sequence currents. With visual or audible indicators, it helps line patrol staff to fast find out the location where there is a short circuit or grounding fault on the 3kV-40.5kV power distribution networks, switchgears or cable branching units etc.

  • VPIS High Voltage Indicator

    High Voltage Indicator

    DXN3-T High Voltage Indicator indicates the voltage status of the main circuit of the high voltage electrical equipments, preventing electrical misoperation and accidental entry into the area with high voltage presence.

  • RMU instrument transformer

    Instrument Transformer

    LMZK3 split core instrument transformer is suitable for measurement of primary current, or for protection of electrical equipments such as microcomputer in 10KV and 35KV AC power distribution networks. It is widely used in fully insulated ring network switchgears such as ABB-Safe Ring/Safe Plus...and cable distribution boxes. The transformer can be directly installed at the inlet and outlet of the GIS or AIS cables. The semicircular ring core and secondary windings are vacuum poured by insulated resin. This CT is also used for signal acquisition for RTU or FTU.

  • Motor Drive Operating Mechanism working principle

    Motor Drive Operating Mechanism

    AD DC 3 – S / AC220 series of Motor Drive Operating Mechanism are applicable for modules of ABB safe cabinets. Operated by motor gear, it can store energy to make-and-break the circuit breakers of MV switchgears. Functions include Remote/local switching and local make-and-break of switches, local and remote indication of the status of load switches, earth switches and fuses.

  • Switchgear temperature control

    Switchgear Temperature Controller

    KST series of small-sized temperature controller and bimetallic thermostat dedicated for switchgears 10℃. It can automatically start fans or heaters and adjust temperature and humidity of the surrounding according to on-site situation. The contacts will output action indication signals, when ambient temperature is higher than pre- set temperature, the contact of controller will flip so to protect the equipments from being damaged.
