EVER-Tap vacuum interrupting voltage regulator

The EVER-Tap vacuum interrupting voltage regulator is the result of a significant collaboration between two industry leaders: Eaton and Reinhausen Manufacturing. Eaton’s long-standing experience with step-voltage regulators and controls combined with Reinhausen’s industry-proven VACUTAP RMV-II tap changer resulted in a reliable, efficient and flexible voltage regulating solution for your substation.

Accurate neutral position identification
Supervision of "safe to bypass" actions with one displayed signal
Reinhausen VACUTAP RMV-II vacuum interrupting tap changer
Rated for an industry-leading 1,000,000 operations
DER algorithms
Reduce operations by up to 70% in high PV penetration applications

Core features

  • Improves CVR with single-phase substation voltage regulation, addressing phase unbalance issues and achieving cost-saving goals
  • Handles substation applications with power transformers up to 56 MVA, 150 kV BIL
  • Monitors and adjusts each phase independently or can be set up for a three-phase ganged operation, simulating a power transformer with OLTC
  • Analog card inputs provide real-time health status – monitoring oil temperature, pressure/vacuum or fan control – avoiding costly site visits

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-II 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.
