1. Application
FTCT-1000A CT/PT Analyzer is mainly used for field testing of P class CT and PT. The test items mainly include excitation characteristic, transformation ratio, polarity, demagnetization, 5% and 10% error curves, secondary circuit check, withstand test of power frequency alternating current and secondary load. Adopt LCD, built-in printer supporting field printing; supporting to use USB flash disk to dump data, with simple and convenient operation.
2. Current Transformer (CT)?
A current transformer (CT) is a type of transformer that is used to reduce or multiply an alternating current (AC). It produces a current in its secondary which is proportional to the current in its primary.
Current transformers, along with voltage or potential transformers, are instrument transformers. Instrument transformers scale the large values of voltage or current to small, standardized values that are easy to handle for measuring instruments and protective relays. The instrument transformers isolate measurement or protection circuits from the high voltage of the primary system. A current transformer provides a secondary current that is accurately proportional to the current flowing in its primary. The current transformer presents a negligible load to the primary circuit.
Current transformers are the current-sensing units of the power system and are used at generating stations, electrical substations, and in industrial and commercial electric power distribution.
