The VIA has been designed specifically for Ground Fault Indication on Wye or Delta-connected, three-phase, three-wire, resistance grounded or ungrounded power systems. It may be used on systems between 120 volts or 600 volts (up to 690 without CSA approval) or up to any voltage with the use of 120 volts or 240 volts potential transformers (PT’s).

The I-Gard VIA is a Voltage Indication Alarm unit created to provide an early warning in the event of a single ground fault and to indicate on which phase the fault occurred. The VIA has been designed specifically for ground fault Indication on Wye or Delta-connected, three-phase, three-wire, resistance grounded or ungrounded power systems.

At I-Gard, we are using the industry’s most advanced line of GROUND FAULT, ARC FLASH AND NEUTRAL GROUNDING RESISTORS, combined with our unparalleled APPLICATION EXPERIENCE and TECHNICAL EXPERTISE.

The document describes an I-Gard voltage alarm indicator that detects ground faults on 3-phase power systems. It provides fault level indication through LED lights and auxiliary relays. The device monitors phases directly without additional hardware. Optional external displays can be connected for remote fault indication.
