The DART, a pioneer of transducer-less feeder-resident IEDs, has proven to be reliable in some of the harshest conditions on the planet. The entire product family is composed of devices that operate from -40°C to +80°C at 100% humidity without the need for any environmental control. The DART monitors up to 12 AC inputs directly from PTs, CTs or line post sensors. In addition to voltage and current magnitudes, the DART calculates power, power factor, phase angle, power flow direction, and import/export energy. A three-phase fault detector signals over-current, breaker operation and lockout on a per phase basis for line-to-line and line-to-ground faults.
