Causes and Treatment Analysis of Secondary Open Circuit of Current Transformer
The test terminal in the AC current loop, due to structural and quality defects, causes poor contact between the screw and the copper plate screw hole during operation, resulting in an open circuit.
What are the problems with the daily use of current transformers?
Current transformers are generally marked with a reduced polarity. If the polarity is not connected correctly, it will affect the metering. Even when multiple currents in the same line are connected in parallel, all of them will cause a short circuit accident.
What are the wiring methods of current transformers?
The current transformer is connected by two-phase V-shaped wiring and two-phase current difference wiring using two current transformers; three-phase Y-connection, three-phase delta connection and zero-sequence wiring using three current transformers.
