Current Transformers

3 Phase AC Current Transformers

  • To be used with GIMA three phase meters
  • Equipped with terminals to permit easy connection to the GIMA units
  • These terminals are #8-32 brass studs and come with a flatwasher, lockwasher and a regular nut (leads are not provided).

Donut Current Transformers

  • Donut and Terminal Style that Reduce High AC Current Signals to 5 AC Amperes
  • Model 186 Reduces High AC Current Signals to 10 AC Volts

Split Core Current Transformers

Offer a cost effective and efficient method by which the current can be measured without the need to break the conductor, thereby reducing installation and commissioning time.


Model 186 Current Transformer

  • Optimal for remote sensing of AC current signals
  • Converts AC current signal to 0-10 ACV signal
  • For use with rectifier type analog panel meters or digital indicators
  • Perfect for low current measurement where a donut current transformer would not sense a signal

Current Transformers with Terminals

  • Reduces high AC current signal to 5 amp AC signal
  • Use with analog digital indicators
