5. EUROPE S SELECTION OF TEST amp MEASUREMENT EQUIPMENT FOR HIRE Nationwide Low Call g ry OMICRON CT Analyzer Revolution in Current Transformer Testing and Calibration A OMICRON Revolutionary Way of CT Testing Current transformers are used for relaying and metering purposes in electrical power systems They connect the high power primary side to the protection and metering equipment on the secondary side Depending on the application they are used for current transformers are designed differently Protection current transformers As it is used to feed protective relays the CT must be accurate during normal and fault conditions Failures in transformation could lead to misoperation of the relay along with unwanted and costly outages To test CTs according to the requirements of modern protection systems it is compulsory to consider transient components and auto reclosure systems Metering current transformers CTs for metering purposes must provide high accuracy up to class 0 1 to guarantee correct billing It is therefore essential to test and calibrate the metering current transformer as the entire metering chain is only as accurate as the instrument transformers feeding the meter In contrast to protection CTs metering CTs must go into saturation directly above the nominal primary current level to protect the connected metering equipment CT Analyzer a new way of testing CTs The CT Analyzer
