PDHs: 9

Course Base Fees: $600*
* Plus Applicable Tax


Course Information

This course is 2.5 hours per day over 4 days.

Course Base Fees: $600 USD

WBT 103 will provide students with an in-depth understanding of the power utility's application of power line carrier as its used in transmission pilot schemes. The workshop will meet in a virtual training environment for four live, instructor-led sessions. Students will be expected to complete homework projects between the first and second training sessions and the third and fourth training sessions.


This course is for protection engineers or technicians who already possess a basic understanding of transmission line protection and want to learn about the application of power line carrier.
