ground fault detection current transformer | AVR Freaks· For ac detection the core balance technique works by measuring the difference in the active and neutral currents. With no leakage, these currents are equal. This is done by passing the active and neutral both through a current transformer. The current transformer now reads the difference in current. Loop the wires more for greater sensitivity.input voltage of transformer?3/19/2009Electronic transformer9/3/2002Voltage regulator problems...11/13/2001Measuring leakage current in 3-phase system with current transformer8/2/2001See more results
