Special Distribution Transformers

Substation Transformers

Substation Transformers

GE Prolec’s distribution transformers are designed for the diverse mining, oil and gas and distribution markets of North America and international applications. Our distribution substation transformers are suited for real-world applications because we rely on extensive customer input and feedback to determine the ideal product testing and quality parameters. Prolec GE has extensive experience designing transformers for heavy duty mining applications such as crushing, grinding, floatation & refining/palletization. We deliver advanced performance under the most demanding operating conditions for offshore operations, exploration and production, as well as onshore operations, refining, petrochemical and storage.

Key benefits

  • Rating up to 7,500 kVA
  • Available in ranges from 225 kVA to 12000 kVA, to 69 kV, 200 kV BIL

Network Transformers & Voltage Regulators

Power Transformer

Network Transformer

GE's Safe-NET network transformers are the safest transformers available in the industry for secondary network applications. Safe-NET network transformers are available for subway and vault applications. The Safe-NET transformer is designed to supply power to the network bus and is capable of handling significant short-term overload conditions in this application. It also has one of the smallest foot prints and delivers more KVA per square inch compared to competing products. GE's exclusive transformer tank design features patented tank technology that minimizes the danger from a transformer rupture event, mitigating its impact to adjacent assets and public safety.

Voltage Regulator

GE’s family of voltage regulators are cost effective, robust solutions to regulate voltage without comprising quality and reliability, providing a total cost of ownership that is nearly 20% better than competing products. The VR-1 regulator is designed to provide utilities with a means to protect themselves and their customer against the detrimental effects of voltage variation. Optimum regulation is achieved by controlling the voltage as close to a predetermined level as practical and is “Designed with the Utility in Mind”. GE’s voltage regulators comply with IEEE® C57.15-2009 and NEMA® 4, and are independently certified by KEMA® that the VR-1 meets the stringent Short-Circuit requirements in the IEEE standard. They can operate up to 2 million mechanical operations, providing years of reliable service without costly maintenance. Additionally, GE is one of the first to incorporate measured reverse power flow capability, which is critical on today’s distribution circuits where distributed generation is present.
