NK Technologies Ground fault indicators
The AGT Series of ground fault indicators produces an analog 4–20 mA signal proportional to earth or ground fault current. When connected to a controller or data logger, NEC requirements for alarm can be met. Applications include current leakage detection and accurate measurement of light loads. Features include true RMS output (remains accurate on distorted waveforms such as VFD or SCR outputs), single range (eliminates field range selection errors and zero and span pots) and isolation (magnetically isolates output from the input for safety and eliminates insertion loss). The indicators are UL- and CUL 508-listed.
