Voltage regulators

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.

Optimise energy savings, power quality and asset management while minimising power interruptions

Eaton’s Cooper Power series voltage regulators are part of a comprehensive power management portfolio, an integral element of your Smarter Grid operation, and backed by expert technical support. Proactive maintenance and quick alerts to impending issues minimise maintenance costs and system downtimes. Exclusive features such as duty cycle monitor, preventative maintenance tapping and motor trouble diagnostics are available to alert users to maintenance needs.
