About us

Horstmann was founded in 1946 and since that time it has been a successful family-owned company. Due to its long experience and the ongoing expansion activities in research and development we are today recognized as a leading manufacturer in medium voltage technology for:

  • Short-circuit and earth fault indicators
  • Voltage testers and voltage detecting systems
  • Earthing devices and accessories.

The worldwide distribution is covered by both our own highly qualified sales force and international representatives. Our products meet highest quality requirements and are developed and manufactured in own production facilities in Germany. In order to respond to these demands, we have a very high vertical depth of production (e. g. own SMD assembly system) as well as an own research and development department with state-of-the-art testing and measuring equipment.

Besides the electronics manufacturing, we have also a mechanical production facility for safety material.

Products and services

Solutions for medium voltage distribution networks:

  • Short-circuit and earth fault indicators (directional) 
  • Solutions for smart monitoring and fault detection
  • Remote monitoring/connection to local SCADA
  • Voltage detectors and phase-comparators
  • Voltage detecting systems
  • Grounding devices, hot sticks and safety equipment
Earth 4.0

The Earth 4.0 is an earth fault indicator. It is designed to detect, locally indicate and remotely report earth faults in medium voltage distribution networks. A current transformer monitors the summation current of all three conductors. The electronics of the display unit evaluates the measurements. When the fault sensitivity threshold is exceeded, a red LED will start flashing and a mechanical flag becomes visible. In addition the remote indication contacts are energized.

ComPass AX12

The ComPass AX12 solution is a combined earth fault
and short-circuit indicator with an integrated RTU. Alarms and warnings are reported immediately with date/time stamp to SCADA. It provides important grid parameters from the medium voltage network. Utilities are able to analyse and evaluate a variety of information, leading to better understanding and management of complex underground medium voltage networks. Furthermore, the utilities will be able to be more proactive in preventing incidents.

ComPass B 2.0 / ComPass Bs 2.0

The directional short-circuit and earth fault indicator ComPass B 2.0 supplies measured values of current, voltage and power from the station for transmission to SCADA. For all measured values limits are exceeded.

Additionally, the ComPass Bs 2.0 provides a control function to operate load-break switches. A free assignment of 6 binary inputs in combination with a freely programmable logic offers a flexible definition of switching conditions.
