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. These increased operations reduce the typical voltage regulator life expectancy and increases the ongoing maintenance cost for reliable operation. The ongoing maintenance requirement of most voltage regulators, along with the reliability cost associated with unit performance contribute significantly to the total cost of ownership for voltage regulators. GE's Solution GE’s family of Voltage Regulators set the industry standard in terms of robust design and product reliability. The GE design fully complies with the strict requirements of IEEE® C57.15-2009 and NEMA® 4, and is independently certified by KEMA®. GE Voltage Regulators can operate up to 2 million mechanical operations, providing years of reliable service without having to incur costly maintenance outages. GE offers cost effective, robust solutions to regulate voltage on the network without comprising quality and reliability, providing a total cost of ownership that is nearly 20% better than other competing products. Additionally, GE is one of the first in the market to incorporate measured Reverse Power Flow capability to the voltage regulator. The new feature provides precise synchronous operation of the tap changer and control during normal and reverse power flow, which is critical on today’s distribution circuits where distributed generation is present. Applications of Single Phase Voltage Regulation • Fast Cycle Pole-mounted Voltage Regulator • Traditional Pole-mounted Voltage Regulator • Substation Voltage Regulator • 20 years maintenance free operation reduces total cost of ownership • Only voltage regulator on the market that does not come with a required maintenance program • Best in class Load Tap Changer (LTC) switch, with the longest switching mechanism life and proven 2 million mechanical operations • Superior internal arrester provides less stress to the coil under lightning/impulse surge events Standards Compliant • Fully complies with ANSI® requirements and IEEE standards • Design validated by KEMA to adhere to the latest IEEE C57.15-2009 standards • Fast Cycle voltage regulator clamp type terminals, remote mount controller and 3 operating taps comply to IEEE requirements • Traditional pole-mounted units designed to meet the full ANSI rating (40x rated current) • Heavy duty lifting lugs on cover and tank Flexible Design • Standardized plug and play design provides flexibility to integrate multiple controllers • Compatible with multiple state of the art, microprocessor programmable controls • One cabinet fits most standard control modules • Newly designed control cabinet configurable for most control / communication options; meets NEMA 3R/4 and UL50 requirements • Forward and reverse power flow measurements for proper volt/var management

Voltage Regulators Voltage Regulator Applications Feeder Regulation Within The Substation Voltage regulation on electrical networks is a complex process. It involves a number of key assets working collaboratively to maintain a consistent voltage profile while the variable loads and distributed generation within the network are continually changing. The transformers located within the substation, usually operate with a Load Tap Changer (LTC) and manage the voltage levels for the bus that may feed multiple circuits that are served from the substation. The transformer provides a baseline...

Regulation For Specific Loads on a Feeder There are instances where the entire feeder does not need to be adjusted. An example is an industrial complex, with a large number of motors and other inductive loads. In these circumstances, a pole-mounted voltage regulator is used within the circuit to adjust the voltage level to adequately serve that end user. The pole-mounted voltage regulator is typically adjusted automatically, and must operate in conjunction with the substation voltage regulator and the substation transformer. Benefits of Voltage Regulation Managing voltage profiles with...
