SKU: TDPTR00CENDuration: 60 Minutes

The purpose of this course is to teach the basic procedures used to safely remove and install pole top transformers. Although specific types of transformers are used as examples, emphasis is placed on general procedures that apply to the majority of pole top transformers. At the conclusion of this course, participants should understand the basic procedures for replacing pole top transformers safely and efficiently. Their understanding should include how to use a boom or blocks and a truck-mounted winch to install or remove a transformer and the basic techniques used to connect and disconnect pole top transformers. They should also be familiar with some methods commonly used to replace a transformer without interrupting customer service, and they should know how to use the appropriate safety equipment for transformer replacement procedures.
