Aging Switchgear: Retrofit vs. Replacement

Aging equipment requires more maintenance. Spare parts are difficult to obtain, and repair is often time-consuming and costly. Once you have examined the current state of your switchgear, the decision to continue to repair or replace the whole system enters the pictures. Is this all you have to decide on?

Indeed, there is a third option: upgrade aging switchgear. In most cases, there’s no need to remove all the equipment. Switchgear modernization solutions – called Retrofits – are the better and more economic choice, as they utilize the structure and footprint of the existing line-up and upgrade the active components with current technology circuit breakers.

This allows older installations to be modernised at low cost and brought up to the current state of the art. Retrofitting usually only replaces the circuit-breaker, i.e. the core component of the installation, its "heart" so to speak. The old is replaced by a circuit-breaker of the latest generation from well-known manufactures, such as AEG, Alstom, Siemens, etc. This is adapted to the busbar system of the switchgear simply by plug-and-play, without any complex conversion measures.

The advantages of a Retrofit are obvious:

  • Short realisation time
  • Reduced planning effort, no approval procedures
  • Low investment costs
  • Reduction of operating costs
  • Minimal downtime
  • No training required, as the switchgear is well known
  • Reduced environmental impact, due to fewer discarded materials
