SWITCHGEAR MAINTENANCE

The importance of carrying out preventative maintenance on medium voltage switchgear cannot be over emphasised. Lack of preventative maintenance can lead to mal-operation of equipment which can lead to blowouts, exposing the switchgear operators to danger. Lack of servicing the circuit breakers leads to their mechanisms becoming clogged with impurities like dust resulting in the circuit breakers failing to operate as and when required. Outages consequently translate to loss of production time which will affect profitability of operations.
