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.

Quik-Drive tap changer
Most advanced and fastest tap changer in the industry
Voltage regulation of 32 steps (approximately 5/8% per steps) for a maximum of ± 10% in wye-connected banks
Advanced CL-7 SCADA-ready voltage regulator control
Quik-drive tap changers: 32 steps in under 10 seconds
Voltage ratings are available from 2400 volts (60 kV BIL) to 34,500 volts (200 kV BIL) for 60 Hz and 50 Hz systems
Product support and expertise that is unmatched in the industry
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.
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.
