An intensive professional development training course on

Characteristics, Operations and Maintenance of Variable Speed Drives, Uninterruptible Power Supply and Electrical Protection

Why Choose this Training Course?

The training course covers all salient topics related to variable speed drives, uninterruptible power supplies and electrical protection relays. It will include the construction operation and maintenance of those equipment. Variable speed drives are gaining fast popularity and visibility in most electrical installation. Its energy saving characteristics couple with superior variable speed applications has been the choice of most electrical facilities.

The uninterruptible power supply is another essential equipment modern day electrical installation where a resilient power system is a high demand. The correct choice of uninterruptible power supply selection is important to ensure continuous power flow during outages.

Precision and reliable protection relays are incorporated in all electrical installation systems to ensure safety to personnel and prevent unwarranted damage to the electrical equipment. Conventional electrical protection relays has now migrated to the electronics numerical relay which has wide array of protection schemes. Upon energization of these relays the circuit breaker will operate efficiently.
