• hxd410 fault circuit indicator

  hxd410 is a type of fci which is designed to be installed on distribution overhead lines. it can detect overload, short-circuit and ground fault. furthermore, it can recognize transient fault and permanent faults. this model can indicate the fault by lec illumination as well as rotary flag (in red color).  meanwhile, if the system is equipped with rf module then it can provide remote alarm for dispatching center (or control station).

• hxd420 data collection unit

  hxd420 is a data collection unit (dcu) to manage and configure hxd410 fcis.
  

  hxd420 dcu collects fault data from fci and then communicates with central control station via 2g/3g/4g (using scada system).

• hxd430 fault circuit indicator

  hxd430 is a type of fci which is designed for underground applications. each set of hxd430 contains 3 over-current sensors and 1 zero-sequence sensor. the over-current sensors clamp on each of three phase and zero-sequence sensor clamps on the cable (one sensor for all 3 phases). over-current sensors can detect short-circuit fault and zero-sequence sensor can detect ground fault. all sensors provide local indication and remote alert (via optical fiber). also a display panel is offered to show line current and fault status.
