The testing and verification of protection devices and arrangements introduces a number of issues. This happens because the main function of protection devices is related to operation under fault conditions so these devices cannot be tested under normal operating conditions. This problem is worsened by the growing complexity of protection arrangements, application of protection relays with extensive software functionalities, and frequently used Ethernet peer-to-peer logic. The testing and verification of relay protection devices can be divided into four groups: Routine factory production tests Type tests Commissioning tests Occasional maintenance tests This course is suitable for electrical engineers with a desire to understand the fundamentals of protection relay testing and commissioning. Presented details cover basic testing terminology, various tests including factory production, type tests, commissioning and maintenance tests. Upon successful completion engineers will be able to address different tests, related procedures, outcomes, simulation hardware and software and procedures during protection relay commissioning and occasional maintenance. Learning Objectives This continuing education course is intended to provide you with the following specific knowledge and skills:
