AGT Series

AGT Series Ground Fault Protection Sensors

AGT Series Ground Fault Protection Sensors combine a current transformer and a True RMS signal conditioner into a single package. The AGT Series Ground Fault Protection Sensors are designed to produce an analog 4-20 mA signal proportional to earth or ground fault current. Available in a solid-core case. When connected to a controller or data logger, NEC requirements for alarm can be met.

Current Leakage Detection
  • Monitor heating or other loads to detect increasing leakage current
  • Pass all current carrying conductors through aperture to sense zero-sum current
Very Light Loads
  • Accurate measurement of very small but critical loads
  • Current measurement gives faster response than temperature measurement
True RMS Output
  • True RMS technology is accurate on distorted waveforms like VFD or SCR outputs
Single Range
  • No chance of field range selection errors
  • Eliminates zero and span pots
Isolation
  • Output is magnetically isolated from the input for safety
  • Eliminates insertion loss
