POWER SYSTEM PROTECTION FOR MEDIUM VOLTAGE AND LOW VOLTAGE
19 - 20 OCTOBER 2026
8 CDP Approved by ST
COURSE INTRODUCTION
This programme develops practical understanding of protection systems used in low- and medium-voltage electrical distribution networks up to 33 kV. Participants review fault types, protection principles, devices, relay functions, coordination, testing, maintenance and regulatory considerations to support safer and more reliable distribution-system operation. Practical examples and guided discussion help participants connect the subject to decisions and challenges in their own workplace.
COURSE OBJECTIVES
By the end of this programme, participants should be able to:
- Explain the purpose, selectivity, sensitivity, speed and reliability requirements of protection systems.
- Identify common faults in low- and medium-voltage distribution networks.
- Compare unit, non-unit, overcurrent, earth-fault and earth-leakage protection.
- Interpret the roles of current transformers, relays and circuit breakers.
- Coordinate protective-device settings for safer and more selective fault clearance.
- Apply electrical-safety and Malaysian regulatory requirements to protection work.
WHO SHOULD ATTEND
This programme is suitable for electrical engineers, chargemen, wiremen, technicians, supervisors and operations or maintenance personnel responsible for low- and medium-voltage distribution and protection systems.
