Current Transformers

Standex Electronics has a long history of developing current transformers to solve unique customer challenges. Current transformers (C.T.) are used in power supplies to accurately sense and measure current flow. Their primary function is to prevent overcurrent conditions as well as monitor and control power supply circuits. Utility companies are turning to smart meters to ensure efficient use of electricity. CT’s play an integral role in the smart grids’ ability to measure, monitor, collect and analyze how electricity is being used. 

Additionally, our custom engineered transformers are designed for extreme conditions and hazards. Such as high temperature, radiation, humidity and other extreme environmental needs.

“Standex Electronics provides global support for a wide range of current sensing applications.”

Typical Current Sense Applications

  • Over-current sensing for circuit breakers
  • Isolated current sensing for appliances
  • Load variation sensing for frozen drink machines
  • Current sense transformers for load house monitoring
  • Over-current sensing for home appliances
  • Transformers to power refrigeration units for refrigerated trailers
  • Automatic transfer switches
  • Current monitoring for power factor
