Safety through earthing and short-circuiting
Earthing devices
We offer you a comprehensive and high-quality range of earthing devices that are specially designed for the safety requirements of portable devices.
Safety for people and technology
Operators of medium-voltage grids know that the reliable transmission of electrical energy is not everything. Safe operation plays an equally central role – both for people and for the technology. The earthing and short-circuiting devices from Dipl.-Ing. H. Horstmann GmbH play a key role here.
With our portable devices, we enable you to safely and quickly temporarily earth or earth and short-circuit disconnected or de-energized systems. Avoid dangerous voltages and electric arcs in the event of unintentional reconnection and reliably protect your employees and your systems.
Customized solutions for your requirements
Our earthing and short-circuiting devices are designed to meet high safety standards while taking into account the special requirements of your systems.
Our team will be happy to assist you in selecting the right earthing and short-circuiting device. We take important parameters into account:
- Length of the ropes
- Type of star point earthing (rigid or not)
- Short-circuit measurement time (tr)
- Short-circuit rated current (Ir)
- Short-circuit rating crest factor
- Required phase and earthing fixed points
Phase fixed point
Phase connection terminal
Earthing rod
Earth potential connection
Grounding fixed point
Important features at a glance
- Flexible product range: We offer the right solution for almost every requirement.
- Use in various networks: Earthing and short-circuiting devices with reduced earth wire cross-section can be used in all networks without direct star point earthing (in accordance with IEC 61230 or VDE 0683-100).
- Quick adaptation: lengths of earthing and short-circuiting cables are adapted to the dimensions of your systems and the distances between the connection points.
Temperature sensor and QR code in the connecting element of our EKVs
SPECIAL FEATURES
-
The temperature sensor at the heart of the new Horstmann EKVs makes visual inspection easier and increases user safety. If the temperature measuring point in the connecting element has tripped (white point turns irreversibly black), it can be assumed that the EKV has been exposed to a short-circuit current. The EKV must then be excluded from further use.
-
A QR code in the new connecting element means that the digital version of the operating instructions can be called up at any time using a smartphone.
With these new safety features on our earthing and short-circuiting devices, we are setting a new standard for safety and ease of use. Horstmann remains true to its mission to make the medium voltage working environment safer and more efficient.

Contact us
Take advantage of our many years of experience and technical expertise. Horstmann is your reliable partner for earthing and short-circuiting devices in medium-voltage technology.
Contact us to arrange an individual consultation on topics such as defining the cable length, determining the appropriate EKV for the type of neutral point treatment – rigid or not – or determining the type of connection parts.
The same applies to the parameters for the short-circuit rated time tr, the short-circuit rated current Ir and, last but not least, the short-circuit rated crest factor.
