Using COMTRADE records to commission protection

This paper demonstrates how to commission specific protection functions using COMTRADE-an IEEE standard for common format for transient data exchange. The following are required to generate a specific test: (1.) detailed test plan (2.) COMTRADE records ¹Each detailed test plan should provide a complete explanation of the test as well as step-by-step instructions on performing the test. Each detailed test plan should also provide an explanation as to why the test is useful to perform, such as preventing a common type of misoperation from re-occurring. Some functional tests may only require a COMTRADE record to inject test signals into the relay. Tests that can be performed using a generic COMTRADE record greatly simplify the test plan and can provide test results based upon actual system conditions.
