Product Profile of Instrument Transformers
ABB is well known for a wide range of Instrument Transformers. The transformers provide accurate inputs to protection, control and metering systems including revenue metering. The main features of Instrument transformers are as follows:
1 To transform currents or voltages from a usually high value to a value easy to handle for relays and instruments
2 To insulate the metering circuit from the primary high voltage system
3 To provide possibilities of standardizing the instruments and relays to a few rated currents and voltages.
The models of instrument transformers are Current Transformers, Voltage Transformers, Combined Current/Voltage Transformers and Coupling Capacitors for power line carrier applications.
