Miniature Current Transformer Technical Jargon
Miniature current transformers are important components for a variety of areas in the industry. Technical jargon is the keyword for ordering mini current transformers. It’s also important to be familiar with the structure of a typical product. According to the Chinese Industry Standard, many technical terms have been defined. Here we introduce some of these terms and give detail explain.
Instrument transformer is a type of transformer that is used for instruments, meters, relays or some other similar electrical devices.
A current transformer is a type of instrument transformer that is designed to produce an alternating current in its secondary winding which is proportional to the current in its primary while properly used. Its phase displacement is nearly 0 while the wiring method is correct.
The primary winding is a winding forming the part of an electrical circuit such that changing current in it induces a current in a neighboring circuit.
The secondary winding is a winding such that current is induced in it by passing a current through the primary coil and act as the source of measuring instruments, meters, relays or other similar electrical devices.
Rated frequency is frequency required or stipulated by some standards.
Rated Primary Current
Rated primary current is the primary current value act as the standard of performance for current transformers.
Rated Secondary Current
Rated secondary current is the secondary current value act as the standard of performance for current transformers.
Maximum Current ( Imax )
The maximum current is the maximum working current of the instrument transformer within its accuracy class.
Miniature Current Transformer
A miniature current transformer is a current transformer with a rated secondary current no more than 100mA.
Actual Transformation Ratio
The actual transformation ratio is the ratio of primary current to secondary current at work.
Rated Transformation Ratio
Rated transformation ratio is the ratio of rated primary current to rated secondary current.
