Drying out the transformer. If the transformer appears to have been damaged internally, or if it is desirable to remove the core-and-coil assembly for inspection or drying, the transformer may be untanked as follows: 1. Remove the handhole lid and disconnect high-and low-voltage leads if the bushings are in position. Remove large bushings from cover if any.

Voltage Regulators Robust Maintenance Free Solutions The voltage on modern distribution circuits is becoming increasing difficult to manage. New distributed energy resources, such as solar, combined with the growth of sophisticated loads creates voltage challenges on distribution network systems. Existing voltage control devices cannot maintain a consistent voltage profile, especially when trying to manage the intermittency of these resources and loads. These new loads and intermittent resources tend to drive the voltage regulation beyond its designed capability, and reduce the typical voltage regulator life expectancy and increase the ongoing maintenance cost for reliable operation. 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. GE’s voltage regulators comply with IEEE® C and NEMA® 4, and are independently certified by KEMA®.

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.
GE hosts Voltage Regulator Training in Shreveport, Louisiana twice per year. The training covers a wide range of topics and complies with the State Engineering Board's requirements for continued education credits. Please check back soon for updates on the next training sessions. Differentiated Value The voltage on modern distribution circuits is becoming increasing difficult to manage. New distributed energy resources, such as solar, combined with the growth of sophisticated loads creates voltage challenges on distribution network systems. GE's robust and reliable Voltage Regulators help to address these challenges. Fast Cycle Voltage Regulator GE's Fast Cycle Voltage Regulator (VR-FC) is a new edition to GE's portfolio of pole-mounted voltage regulators and is based on the most popular utility configurations.
The VR-FC is manufactured with a standard design, providing an optimized feature set, with short-cycle lead times at a competitive based price point. Key Benefits of the VR-FC:. Design efficiency requires less cooling panels, resulting in a smaller footprint and reduced radiation. Sealed position indicator design eliminates complicated fittings which reduces the risk of leaks and water entry. Single Molex quick connect harness to easily interface to most controller options. Heavy duty lugs both on the cover and tank.
Multiple grounding provisions under the source, load and source load bushings. Pole Mounted Voltage Regulator The Pole-mount/platform mount Voltage Regulator (VR-PM) is GE's premium product for voltage control outside the substation and has established the benchmark in the industry for robust design and operational reliability. It is the only voltage regulator on the market that is guaranteed to support 2 million switch operations and adheres to the latest IEEE C and C57.131 standards of 40x rated short circuit current. Substation Voltage Regulator GE's 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.
GE's Voltage Regulation Solutions GE's Voltage Regulation solutions integrate seamlessly into utility optimization and control strategies for voltage regulation, and is comprised of the following components:. Substation voltage regulator with integrated DGC-V controller. Pole-mounted voltage regulators with integrated DGC-V controller. Pole-mounted capacitor banks with integrated DGC-C controller.
Integrated line monitoring devices. Metering for end of line voltage measurements. Integrated communications.
