Electrical Equipment & Control Systems

Electrical Equipment & Control Systems

Commissioning, Testing & Start-Up of Electrical Systems

Introduction

Electrical equipment and devices are vital in all electrical installation to ensure continuity and efficient operations. Equipment like transformers, motors, variable frequency drives, uninterruptible power supplies and batteries are today’s common components in most electrical installations. Safe operations are essential as they are protected by modern and sophisticated relays and protection devices.

Protection systems are installed to prevent faults from damaging electrical plant and to initiate isolation of faulted sections in order to maintain continuity of supply elsewhere on the system. Recent changes in technology together with changes in the manner in which Utilities and Industrial organisations operate, has greatly emphasized the development of integrated protection and control.

This LAKESHORE ISL training seminar will highlight:

  • The Construction and Operations of Transformers and Motors
