Autotransformers
Compared with interconnection transformers of equivalent power flow, the autotransformer presents a lighter and more economically optimized solution which is possible whenever the voltage ratio is between 1 and 2. However, autotransformers have non-disconnected windings, meaning there is no galvanic insulation between the interconnected systems.
Characteristically for complex regulation arrangements, autotransformers impose a total mastership of dielectric phenomena. Designs for constant flux regulation at high voltages or booster schemes are part of GE Vernova’s mastery. For many years, GE Vernova been supplying very high rated autotransformers such as single phase up to 500 MVA and very high voltage up to 765 kV for networks all over the world.
Key features:
- Available up to 765 kV
- Designed for constant flux regulation at high voltages and booster schemes
- Advantages include compact footprint, lighter weight and lower losses
Generator Step up Transformers
GE Vernova’s generator step-up (GSU) transformers are designed and manufactured to stringent standards, providing superior performance and long life. They are suitable for nuclear, thermal and hydraulic applications from small to high voltages with power ratings from 5 MVA to 1000 MVA. The step-up transformers have delta-connected LV windings energized by the generator voltage, while star connected HV windings are connected to the transmission lines.
Constantly faced with voltage changes either due to load rejection or switching operations, followed by generator over excitation, the transformer must also maintain the ability to withstand over-loads. The high rated current involved requires absolute control of the magnetic field inside the tank to avoid localized overheating of associated metallic parts. All of these situations are taken into account by GE Vernova during the design process of individual units and are tested with state-of-the-art techniques.
Thanks to our specific know-how coupled with state-of-the-art modeling and design tools, GE Vernova is able to provide solutions that meet unique power requirements with every installation.
Special Power Transformers
Prolec GE taps into state-of-the-art technology and deep domain expertise in insulation structures, thermal requirements and magnetic field distribution applications, to provide power transformers with exceptional performance, quality and reliability.
PHASE-SHIFTING TRANSFORMERS
As high voltage network systems are connected with each other at several points, the necessity of controlling the flow of energy increases. Classical voltage regulation without phase shifting is no longer sufficient for these situations. GE Vernova’s phase-shifting transformers, rated up to 2750 MVA, are available as single core units with independent phase angle and voltage regulation, and as dual core for higher power and voltages. Quadrature boosters provide an economical solution when limited phase-shifting angles are required with voltage variations.
TRANSFORMERS FOR SVC
GE Vernova’s Static Var Compensator (SVC) systems can help grid operators to gain accurate control of reactive network power, maximize power transfer capability, improve steady-state and dynamic stability within the grid. GE Vernova’s SVC power transformers are custom designed and built to handle harmonic loading and a wide voltage variation. These can be configured as three phase units or a bank of single phase units. The function of the power transformers is to connect the medium voltage equipment to the high voltage transmission grid.

INSTALLATION
Universal Voltage and Current Inputs
This meter allows voltage input measurements 20 Volts to 576 Volts Line to Neutral and up to 721 Volts Line to Line. This ensures proper meter safety when wiring directly to high voltage systems. The unit will perform to specification on 69 Volt, 120 Volt, 230 Volt, 277 Volt and 347 Volt power systems.
Unique Current Input Connections
EPM 7000 meter uses two current input wiring methods.
Method One - CT pass through. Directly pass the CT through the meter without any physical termination on the meter. This insures that the meter cannot be a point of failure on the CT circuit. This is preferable to utility users when sharing relay class CTs. No Burden is added to the secondary CT circuit.
Method Two - Current “Gills.” The meter additionally provides ultra-rugged termination pass through bars allowing the CT leads to be terminated on the meter. This also eliminates any possible point of failure at the meter. This method is also a preferred technique for ensuring relay class CT integrity does not get compromised. No terminal blocks are required and this stud based design ensures that CTs will not open under a fault condition.
Through an optional high speed Modbus communications interface, the meter can also provide data to RTUs, PLCs and other control devices at Baud rates ranging from 9600 baud to 57.6 kbaud.

The N60 includes high accuracy metering and recording for all AC signals. Voltage, current, and power metering are built into the relay as a standard feature. Current and voltage parameters are available as total RMS magnitude, and as fundamental frequency magnitude and angle.
The N60 is the single point for protection, control, metering, and monitoring in one integrated device that can easily be connected directly into DCS or SCADA monitoring and control systems like Viewpoint Monitoring as shown.
FlexLogic™
FlexLogic is the powerful UR-platform programming logic engine that provides the ability to create customized protection and control schemes based on information measured locally by the N60 and received from remote N60s sent to it over the communications network. With FlexLogic, the N60 can use the status of measured inputs, along with the output of the protection elements, FlexElements and FlexMath summators, in Boolean logic equations to perform automated functions for customized special protection schemes.
The N60 contains FlexLogic and FlexMath equations that allow the creation of automated wide area protection and control schemes, remedial action schemes, and other special protection applications.
