State-of-the-art protection – Safety equipment from a single source

Safety technology is one of the most sensitive areas of energy provision no matter what the voltage level. It is a matter of life and death. This means that reliable products, simple operation, and operational safety are absolutely essential. PFISTERER offers a full range of voltage testers, earthing and short-circuiting equipment, earthing and operating poles, and permanent testing systems that are precisely tailored to any requirement thanks to our modular system design.

Doubly secure – Visual and acoustic signals for added safety

Voltage testers need to be reliable and emit clear signals. This is the only way to rule out any risks. PFISTERER voltage testers are designed under the motto: Two is better than one. An acoustic and visual signal issues a clear, double signal if any voltage is applied. Each time the system is switched on, our voltage testers perform a self-test and then report back when they are ready for operation – a key feature when it comes to added safety.

Secure solutions for short circuit currents

Earthing and short-circuiting equipment is subjected to extreme conditions in the event of a short circuit. High temperatures (thermal heat) are generated and dynamic forces are applied to connections and connecting elements. To be able to absorb short circuit currents, earthing cables need to be designed to withstand these loads. Our portfolio covers a wide range of requirements and sizes all over the world. The stable design of our earthing and operating poles, which act as additional insulation, has proven successful in practice and guarantees a long service life.

Individual solutions for any application

PFISTERER's safety equipment covers all possible customer requirements. Our modular system offers maximum flexibility for all types of application, such as switchgears, overhead lines, and railway systems. PFISTERER experts transform problems into ideas and develop solutions according to our customers' individual requests and specifications, even creating brand new innovations. Furthermore, PFISTERER also offers an end-to-end service for routine inspections for all relevant products.


The longest railway tunnel in the world has to remain accessible in any situation, even when repairing the tracks. The unobstructed and fully-accessible earthing and short-circuit devices by PFISTERER make this possible.
