74T/CCS Trip and Close Circuit Supervision The trip or close circuit(s) can be monitored via binary inputs. Trip circuit failure raises an HMI alarm and output(s). 81HBL2 Inrush Restraint Where second harmonic current is detected (i.e. during transformer energisation) user selectable elements can be blocked and an alarm given. 81THD Total Harmonic Distortion Supervision Total harmonic distortion is the percentage of harmonics present in fundamental frequency current. THD calculates the 2nd to 15th harmonic currents presents inline current and displayed in the ‘Harmonic Meter’ window as a...
