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.

  • One of the lowest total costs of ownership when compared to other single phase or 3-phase voltage regulators

  • Best in class Load Tap Changer (LTC) switch life, with up to two million operations resulting in up to 20 years of maintenance free usage.

  • Adheres to the latest IEEE C57.15-2009 standards (40x rated current). GE performs Short Circuit testing every year to validate performance

  • Newly designed control cabinet configurable for most major control and communications options; meets NEMA 3R/4 and UL50 requirements and testing

  • Seismic certified and can be installed in most applications around the world
