Circuit breakers & Switchgears (LV, MV, HV)

INTRODUCTION

This training course will emphasize on the types of overcurrent protection devices and the power transformers. It will elaborate on the characteristics and operations of all types of circuit breakers including the interpretation of the time current curves. As for the MV and HV circuit breakers, selection of digital numerical protection relays incorporating the instrument transformers. Routine tests for circuit breakers are essential for safe and secured operations.

Power transformers presence is very significant in all AC electrical transmission and distribution systems. Understanding the significance of the components in a power transformer is essential to ensure a continuous safe operation. Transformer tests are now executed with intelligent measuring and diagnostics instruments. In addition dedicated protection relays for transformers are important to detect any anomalies in the transformers.
