HV Operation Authorization

HV Operation Authorization

INTRODUCTION

This intensive training course is ideal for suitably experienced persons being considered for the duties of authorized person (high voltage electrical) or senior authorized person (high voltage electrical) with respect to HV distribution systems.

This training Course specially for voltage level more than 1000 V up to 35000 V where consider medium and high voltage will be customized to participant’s requirements and will relate to the type of activities that participant’s need to carry out. Each participant will be assessed upon completion of the training course to be assured that they have taken the learning on board.

The output from this course is a recommendation to support an Authorizing Engineer’s /Tech. decision when considering the appointment of Authorized Person. This course aims to provide an understanding of industrial high voltage power systems including statutory regulations, safe operation, protection and fault diagnosis on a wide range of power equipment. The course also enables participants to perform HV switching operations on industrial HV networks to prepare them for HV authorization in accordance with safety rules/regulations.

This intensive training is designed to increase the awareness of the required diagnostic skills of engineers/technicians and maintenance teams on Modern Power systems. The training course will revolve around maintenance, troubleshooting and fault-finding techniques used in today’s modern systems.
