Independent voltage regulation per phase
Address phase unbalance issues for improved power quality
Reinhausen VACUTAP RMV-SVR vacuum interrupting tap changer
Rated for an industry-leading 1,000,000 operations
Separate regulation from the transformer
Substation applications up to 46 MVA and 150 kV BIL

Core features

  • Independent voltage regulation on each phase or three-phase ganged regulation like an OLTC on a power transformer
  • Voltage regulation separated from the power transformer – no need to deenergize the transformer for regulator maintenance
  • CL-7 Control analog input monitoring provides real-time health status via SCADA – oil temperature, pressure/vacuum, fan control – avoid costly site visits
  • CL-7 control offers advanced cybersecurity features with biannual control firmware updates to keep the control on the cutting edge

Voltage regulator and control training

Eaton offers various equipment maintenance, testing and troubleshooting courses. These courses, taught by experienced service technicians, are held at the voltage regulator factory's in-house training facility.

Ease of installation

Watch Eaton’s Engineering Services and Solutions team work with a co-op to install an Eaton Cooper Power series EVER-Tap voltage regulator.

Industry-leading vacuum interrupting tap changer

Eaton’s EVER-Tap voltage regulator utilizes the Reinhausen RMV-SVR vacuum interrupting tap changer, rated for an industry-leading 1,000,000 operations. Inherent to the vacuum interrupting design, material and gas byproducts from tap changing are removed from the dielectric fluid, providing a clean operating environment, prolonging tap changer contact and coil winding life.

Advanced CL-7 voltage regulator control

Eaton’s Cooper Power series CL-7 control is available in a single-phase or multi-phase configuration where one controller is used to monitor and operate three separate single-phase step-voltage regulators, saving time and money on installation and commissioning costs.

CL-7 control analog input card

With Eaton’s Cooper Power series CL-7 control analog input card, a variety of inputs can be monitored such as oil temperature, pressure/vacuum or fan control, providing real-time health status and saving money by avoiding costly site visits.

Avoid DER voltage violations

Make phase unbalance an issue of the past and achieve your cost-saving goals by improving your CVR with single-phase voltage regulation in your substation. Don’t allow your voltage regulating devices to be overtaxed with the ever-increasing amount of DERs on the system by utilizing the proprietary algorithms in Eaton’s Cooper Power series CL-7 single- and multi-phase controls, reducing the number of operations by up to 70% in high PV penetration applications while avoiding voltage violations.
