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:
Solutions for medium voltage distribution networks:
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 and modem 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.
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.
