While not the most expensive assets, current transformers supply input for protective devices (relays), revenue meters, as well as provide information to the power flow control center. They fulfill an important role in providing critical information about the grid network condition including the health of expensive assets such as power transformers and generators. Because of this, a run-to-failure program is not an option for current transformers and combining rigorous quality control along with an effective preventive maintenance program is essential. This webinar will describe how to utilize the EZCT-2000C to achieve this goal, as well as include a review of the standard requirements and design/construction for current transformers in order to analyze the test data with better understanding.
