Single-phase substation voltage regulator

Eaton leads the industry in the application of single-phase voltage regulators into substations regulating loads up to 60 MVA. With features such as fan cooling and insulating fluid filtration, substation voltage regulators provide a viable option superior to the use of On-Load Tap-Changers (OLTC) with the added flexibility of regulation separate from the power transformer.

Advanced step voltage regulation to meet power quality requirements

Voltage regulators provide regulation in 32 steps (approximately 5/8% per steps) for a maximum of ± 10% in wye-connected banks. Proven reliability is backed up by rugged, service-proven tap-changers, superior core-and-coil assemblies and a control designed for the apparatus.

Industry-leading technology

The CL-7 voltage regulator control and Quik-drive tap changer are a package that is unmatched in the industry. The speed of the patented Quik-Drive tap-changer along with the unique Voltage Limiter capabilities of the control enable the fastest response available for extreme voltage swings.

Advanced CL-7 voltage regulator control

The CL-7 voltage regulator meets the needs of system planners today and in the future with integrated SCADA componentry and continuously evolving features such as radio-ready control box, DC power supply, I/O module and AC cabinet power.
