Contact-free switchgear testing

The electronic HSA 205 distance voltage detector from Dehn provides contactless verification of the safe isolation distance on switchgear installations and high voltage overhead lines. The device is self-testing, and the test is performed automatically after switching on the detector. The device has a wide nominal voltage range from 1 – 420 kV/50 Hz with […]

Surge arrester for power over Ethernet

Copa’s new COP907 surge arrester provides superior surge protection for indoor 100/1000 Base-T Ethernet networks. The unit is fully compatible with industry-standard power-over-ethernet (PoE) devices, providing protection to both Ethernet data pairs as well as the PoE DC power feed. This arrester protects all networks and most data applications utilising a RJ45 connection against damage […]

Multi-purpose LV surge arresters

The Dehnguard S – VA (FM) single-pole, pluggable varistor and spark gap-based surge arresters from Dehn are designed for use in LV installations where complete absence of leakage currents is required. They are also ideal for protecting systems with permanent insulation monitoring and traction power supply lines in railway systems. Consisting of a base part […]

An electronic voltage detector is available that features an integrated self-testing device that automatically tests the electronic circuit for correct functioning when the device is switched on. Dehn’s PHE III electronic voltage detector is designed for testing switchgear and overhead lines in indoor and outdoor installations for nominal voltages up to 33 kV, 50 Hz. It […]

Non-contact voltage detector

The ASP non-contact voltage detector kit from Dehn is designed for use in high voltage overhead line networks and outdoor switchgear installations from 110 to 420 kV, 50 Hz. The ASP electronic indicator has an integrated self-testing element that automatically tests the electronic circuit for correct operation after the indicator is switched on. With its […]

Two-pole phase comparator

Dehn’s  PHV phase comparator with glow lamp indicator is in accordance with IEC/EN 61481 (DIN VDE 0682 part 431), and is designed for testing the in-phase condition of three-phase electrical systems.  It is a single basic testing unit with interchangeable colour-coded test prods designed for various applications and selected for the desired nominal voltages. The […]

Electronic voltage detector

An electronic voltage detector is available that features an integrated self-testing device that automatically tests the electronic circuit for correct functioning when the device is switched on. Dehn’s PHE III electronic voltage detector is designed for testing switchgear and overhead lines in indoor and outdoor installations for nominal voltages up to 33 kV at 50 […]

Voltage detectors with SABS approval

Dehn’s PHE III electronic voltage detector has an integrated self-testing element that automatically tests the electronic circuit for correct operation (threshold) after switching on the detector. The detector is only ready for operation if the function test was performed successfully. PHE III voltage detectors have SABS approval and a 44 kV to 132 kV/50 Hz […]

Terminal block with integrated surge protection and disconnect function

Dehn’s Dehnconnect SD2 series surge arresters are designed as space-saving terminal blocks with a width of only 6 mm. These terminal blocks with integrated surge protection have a modular disconnection function that allows them to interrupt the signal circuit for maintenance work. An integrated module ejector disconnects the signal circuit from the terminal equipment. The […]

Surge arrester for universal use

Dehn’s Blitzductor XTU is a surge arrester for instrumentation and automation systems that adapts itself to the installation’s nominal voltage. The combined lightning current and surge arrester can be used for all voltages from 0 to 180 V DC.  Moreover, it continuously adapts its voltage protection level to the currently applied signal voltage and is […]
