Solutions Energy Power Grids

Protection and monitoring for power grids

For power supply companies and distribution network operators, reliable system operation is the top priority. A power outage can result in high costs for corporate customers, for example due to production plant downtime, as well as a reduced quality of life for private customers – and an image problem for grid operators and communities.

Protection against lightning and surge damage is essential for grid and supply reliability. And with increasing diversification in power generation, the requirements for protection and monitoring measures are becoming more complex. Below, we provide an explanation of what needs to be taken into account.

The power grid is becoming more intelligent – and more sensitive

The power grid of the future will feature predominantly decentralised energy generation. Distribution grids receive green electricity from various sources, such as photovoltaic and wind turbine generator systems, and transport it in all directions. This resulting multi-directional flow of energy places new challenges on distribution grid operators. In order to be able to continue to operate the power grids reliably, they must be developed and controlled intelligently.

This enhancement is associated with an increasing proportion of sensitive electronic components. The result is an increased risk of damage to electrical and electronic equipment:

  • Lightning interference
  • Surges
  • Electromagnetic interference
  • Arc faults 

For you as a planning engineer or operator, this entails an increased focus on system protection. With our modern protection concepts for intelligent telecontrol, information and communication technology, we ensure the comprehensive protection of central facilities and systems in the energy industry.

Protect intelligent transformer substations. Safeguard supply.

Local transformer substations are an important link at the interface between medium and low voltage. If they have core components such as remote-controlled switch disconnectors and circuit breakers, controllable local distribution transformers, telecontrol functions and communication and control equipment, they are referred to as intelligent transformer substations.

Our concepts and products protect the sensitive electronics of intelligent transformer substations against damage caused by lightning and surges. We are a competent partner and solution provider – for electricity grid operators and power suppliers as well as for electrical consultants and installation companies. Contact us so we can support you in maintaining constant availability, avoiding economic losses, and safeguarding your personnel resources. So that you can also ensure the safety of the people working on your system, you will find a comprehensive range of protective clothing and equipment in our safety equipment section.
