EARTH-FAULT CONTROLLER

90-240 V AC/DC

Trench’s Earth-Fault Compensation Controllers are advanced systems designed to adjust Arc Suppression Coils (ASCs), to further compensate for earth fault currents, thereby increasing both the safety and efficiency of the system, even under extreme conditions.

CHARACTERISTICS

  • Universal controller for any brand of ASC adjustable under load
  • Built-in 7″ color touch screen
  • Remote display installation possible (communication via Ethernet)
  • Can be installed in a standard 19″ rack
  • Resonance peak through small coil adjustment control mode

APPLICATION AREAS

  • Compensated (resonant earthed) electrical systems
  • Power distribution network
  • Automatic tuning of Arc Suppression Coil

MAIN FEATURES

Trust in our tailor-made solutions for your unique needs

EFC 60s

Trench's EFC60s offers all the proven and established algorithms for tuning arc suppression coils to network conditions. Combining this with a modern hardware design and an easy to use operating concept.

EFC 60m

Superior multi-frequency current injection mode, making the tuning process resistant to network interferences. Current injection is mechanically and electrically integrated in the 19" rack design.

Optional Current Injection Device

ECI, the Current Injection Device is designed to generate differential measurements by injecting current into the zero-phase sequencing system.

Design Features

With customized and parameterized LEDs on the front display. Highly flexible due to software controlled inputs and outputs, free assignment of digital outputs to different status functions.

Hardware Options

Supplied with alternative power supply, additional external digital inputs and outputs and an IEC 61850 Ed2 module. Different assembly options are supported.
