Pad-Mounted Voltage Regulators

Single_Phase_22560.jpg

Eaton's Cooper Power™ series single-phase pad-mounted voltage regulators and 3-in-1 pad-mounted voltage regulators add a dimension to underground system planning. They provide system planners freedom to improve the safety, reliability and power quality in existing and new underground distribution systems. The pad-mounted voltage regulator provides all the functionality of traditional round tank pole-mounted and substation-mounted regulators, with the convenience of pad-mounting

The pad-mounted voltage regulator provides state-of-the-art voltage regulation while reducing installation costs and preserving a more aesthetically pleasing environment. The pad-mounted voltage regulator, in conjunction with pad-mounted transformers and switchgear, can be used to create a modular pad-mounted substation. This substation can be placed in areas that require a low profile installation. It can be placed in unobtrusive sites and possibly in shared rights-of-way.
