Product Announcement:

Short and earth fault locator EOR-1DS released 05.08.2022

Combined earth fault and short circuit indicator EOR-1DS


We are pleased to inform you that the product “Combined Earth Fault and Short Circuit Indicator EOR-1DS” is officially released as of today. You can order the product, if no pre-order has been placed yet, with an assumed delivery time of 5-6 weeks.

The EOR-1DS combines short-circuit and earth fault location in single compact device at an attractive price. The installed device can be used as an non-directional short-circuit and earth fault indicator (pulse location). For this purpose, only Rogowski phase current sensors of type SR55 are needed – and these sensors are included in the package. In addition, it can also be used as a directional short-circuit and earth fault indicator (pulse locating + qu2 wiper), provided that an additional voltage measurement is available. However, the device shows its full potential when you connect modern small signal sensors for high accuracy current and voltage measurement. Together with the built-in protocol support of Modbus RTU, you can not only determine very precise current, voltage and power measurement values without gaps, but also transmit them via remote messaging, for better network transparency. An essential function in times of the energy transition, where conditions in our power grids are changing rapidly and continuously.

The EOR-1DS is characterized by the following product features:

  • Reliable qu2 wiper algorithm at the heart of the short-circuit and ground-fault indicator
  • Pulse location with angle evaluation
  • Small signal sensors for precise current, voltage and power measurements
  • Adapter for the measurement of 100 VAC / 110 VAC or 1 A / 5 A
  • Modbus RTU connection
  • Intuitive operation via the built-in rotary switch
  • Signaling operation by super-cap in case of supply voltage failure
  • Number of relays increased from two to four compared to predecessor unit EOR-1D
  • Changeover from screw terminals to push-in terminals in comparison with predecessor device EOR-1D
