Wiring diagrams for the 2240 series and 2261 series current transformers

Instrument transformer is a general term for voltage transformers and current transformers that are used with electrical instruments. The main purpose of instrument transformers is to extend the measurement range for electrical quantities (voltage, current, power, power factor) on large-current and high-voltage circuits. They serve to convert currents and voltages to levels that are suitable for measurement, and to insulate the instrument, etc. from high-voltage circuitry.

• Regulate AC and DC with high-precision current transformers 
• Current transformer meters from 60-5000 Amp peak
• Units with up to six CTs
