  • Temperature controller
    Publication number: 20090317694
    Abstract: A temperature controller for providing heat to an energy storage device of a power compensator. The energy storage device includes a plurality of high temperature battery units on high potential. The temperature controller includes a pipe network for housing a heat transfer medium. The pipe network includes a main pipe loop and a local pipe loop in each battery unit. Each local pipe loop includes a first end for receiving a heat transfer medium and a second end for exhausting the medium.
