Line voltage regulator for medium voltage grids

Hitachi Energy offers innovative line voltage regulators with RESIBLOC^® transformer technology that automatically compensates for voltage fluctuations in medium-voltage distribution grids. This reliable and efficient solution is an economical alternative to conventional network expansion for installations such as wind and photovoltaic applications.

• Economical solution compared to grid expansion
• Autonomous regulation to a voltage or load-dependent set point
• Connection to the grid control system for remote control or monitoring of the grid
• Use of proven RESIBLOC^® technology
• Energy efficient and environmentally friendly
• Meets the requirements of the new EU EcoDesign regulation 548/2014/EU
• No fire hazard, completely free of oil
• Optimized voltage steps for good voltage stability and a minimum of switching operations
• Mounted fully-assembled in concrete substation, ready-to connect to the grid
• Simple and fast installation
• Possible to relocate in case of new grid requirements
• No need to replace distribution transformers (DT) with regulated DTs
