Online Course: Instrument transformer diagnostics with CPC 100

Summary

Get to know the wide scope of applications and operation of the CPC 100. Learn how to efficiently test CTs and VTs through live demonstrations and theoretical sessions using Primary Test Manager (PTM). Learn how to work with CTs and VTs to gain experience with this application.

Objectives

• Perform commissioning, troubleshooting and periodic tests of CTs and VTs
• Create asset specific test plan including wiring diagram
• Automatic assessment according to industry standards
• Comprehensive reporting, including templates for all standard and advanced tests

 

Content

• Measure the CT and VT ratio or ratio error as functional test of the ITs' performance as part of commissioning tests
• Evaluate the excitation current and the CT’s knee-point to define its error and performance
• Understand the background of the winding resistance measurement to find possible electrical damages in windings or contact problems
• Perform burden measurements to determine the influence of cables and connections on the overall burden impedance
• Check the polarity between the primary and secondary windings of an IT to prevent maloperation of connected protection and metering devices
• Efficiently perform all relevant commissioning test using Primary Test Manager (PTM)
• Automatically generate test reports with Primary Test Manager (PTM)
