Why Choose this Training Course?

Why Choose This Training Course?

Medium and high voltage electrical power switch gears are critical and important components of an electrical installation. The salient equipment are the power transformer, the circuit breaker and the gas insulated switch gear. Currently these switch gears are migrating to eco efficient characteristics incorporating eco-friendly substances like fluids and gases. With regards to the reduction of global warming potential, new green gases are developed to replace the sulfur hexafluoride gas used in circuit breakers. In the gas insulated substations eco-friendly designs are now available incorporating digital components.

Maintenance of the medium and high voltage switch gears have progressed significantly with the emergence of new testing and diagnostics instruments. Remote monitoring has become a norm for high voltage transformers and circuit breakers. The operations of these switch gears have to be a more reliable and secured parameters, by incorporating digital technologies, artificial intelligence and internet of things. This training course will emphasis on operations, characteristics and maintenance of eco efficient of gas insulated switch gears, transformers and circuit breakers.
