WORKSHOP > 27th October 2016:

> Total Testing Solution for High Voltage Substation


Power transformer, Circuit breaker, CT/VT, Protection Relay, Surge Arrestor and Bushing are important power system equipment and, in the event of failure, will cause great economic losses and down time.
Appropriate testing of power equipment could minimize the damage and prevent the incidents as well as improve operation efficiency.
The aim of ISA workshop is to provide engineers opportunity to learn the best technique practises to effectively test substation equipment. This workshop is designed for power system engineers wishing to expand their knowledge of testing practises and reach higher level of expertise. During the workshop, functionality and
usability of ISA testing equipment will be introduced.

Our trainser has a long international experience in training and testing of electrical apparatus.
