1. LZZW type 10kv 11kv 12kv 33kv 35kv indoors high voltage cast resin ct/current transformer
2. CT & PT application
General definitions have been given according to international IEC 60044.
A transformer intended to supply measuring instruments meters, protection relays and other similar apparatus.
An instrument transformer in which the secondary current in normal conditions of use if substantially proportional to the primary current and differs in phase from it by angle which is approximately zero for an appropriated direction of the connections. It isolates the instrument and the protection circuit from the primary side and protect the devices against overliad according to the overcurrent characteristics of the transformer. Current transformer can have several secondary windings with cores of identical of different characteristics completely isolated from each other.
Measuring Current Transformer
A current transformer intended to supply indicating instruments, integrating meters and similar apparatus.
Protective Current Transformer
A current transformer intended to supply protective relays.
The winding through which flows the current to be transformed.
The winding which supplies the current circuits of measuring instruments, meters, relays or similar devices.
