A common challenge for network utilities is managing voltage profiles within operating limits along the feeder. This can be extremely difficult to do with
substation unit transformers, especially in substations that were built and designed for lower and more static load profiles.
In today’s environment, the average load profiles have radically increased and are more dynamic. In this scenario, the unit transformers alone can no
longer efficiently support voltage profiles across the circuits. A substation based voltage regulator is a cost-effective solution to solve this problem without bearing new infrastructure costs.
The GE Substation Voltage Regulator (VR-SS) is a single phase voltage regulator that is intended to support this type of application within a substation. The advantages of single phase units are twofold; they provide the ability to manage each phase independently in the event of unbalanced loads, and they provide redundancy when compared to an individual 3-phase unit.
As with all GE Voltage Regulator products, the VR-SS regulator provides best-in-class total cost of ownership and the robust design does not require
maintenance, allowing for years of reliable operational service.
