Description

DART Distribution Automation Remote Terminal

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 -40C to +80C 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.

The family is powered by a 12V or 24V, high power, temperature compensated charger that permits remote battery testing and alarms loss of line voltage and battery over or low voltage. Battery life is maximized with a low voltage disconnect feature, output voltage temperature compensation, and extremely low ripple.
