ABB extends BDG current transformer portfolio for generator circuit-breakers

2016-09-21 - ABB introduces indoor current transformers BDG 072 A0 and BDG 072 B3 to extend the existing BDG product portfolio with the smallest and the biggest body designs to serve all generator circuit-breakers requirements.
The BDG indoor current transformer without primary conductor is designed for installation in generator circuit-breaker systems (GCB) and extends the portfolio for power grid applications. The BDG is constructed with a built-in design for installation inside of the generator circuit-breaker.

The introduction of the new BDG 072 A0 and BDG 072 B3 complements ABB’s offering of the current transformers for the generator circuit-breaker. All models are epoxy free and designed as multicoil body with multiple variants of inner dimensions and rated primary currents. The total number of inner dimensions in the BDG portfolio is five, rated primary current is up to 57 000 A, rated short-time thermal current is up to 210 kA (3s).
