Products for optical monitoring of high and medium voltage systems

Innovative monitoring products for the energy sector

Many factors have an influence on the energy and power transmission market - one factor is the safety of the transmission systems. With its innovative and trend-setting products in the field of optoelectronic monitoring systems, VOGL Electronic contributes a considerable part to the safe supply of power worldwide in cooperation with numerous renowned power supply companies as well as leading manufacturers of high- and medium-voltage switchgear.

VOGL Electronic´s systems can be used in a variety of applications:
  • Medium and high voltage systems
  • AC and DC systems
  • Gas-insulated and air-insulated switchgearAC and DC installations
  • New and existing switchgear


The light sensor is the base module required for all of our optical products. (LIBO & OTEM).

We offer light sensors for any make and model of gas insulated switchgear by all common manufacturers.
Our optical arc detection system LIBO protects your gas insulated high voltage switchgear and lines.

Benefit from instant localization of arc faults, improved HV-testing, insightful analysis as well as immunity against electromagnetic interference.
Our optical system for the optical monitoring of partial discharges (OTEM) protects your high voltage gas insulated switchgear against failures due to partial discharges.

Furthermore OTEM enables instant localization of faulty gas compartments as well as identification of the specific fault type. Just like all of our optical systems, OTEM is immune against electromagnetic interference.

For Power Transformers

Our light sensor for transformers is the base module for our optical partial discharge monitoring system (OTEM).

We offer light sensors for any make and model of transformers by all common manufacturers.
The OTEM-system offers high-precision optical partial discharge monitoring for your transformer.

OTEM enables instant localization of partial discharges and provides insights into the condition of your transformer.

For Medium-Voltage Switchgear

The ESK-system offers reliable detection of earth faults/phase faults in medium voltage switchgear up to 110kV.

Affected components get shut down, bevor significant damage can occur.

For all Assets

Special projects require special technology. We develop, manufacture and deliver custom built products for your medium- and high voltage assets.
Vogl Electronic - for a safe power supply

Secure your grid against outages and stay informed regarding the condition of your switchgear at all times.
