Abstract
Abstract A rod shaped varistor having a high breakdown voltage is connected across a source of high voltage so as to maintain the output voltage at a substantially constant value. The varistor is provided with a ring-shaped terminal for deriving an intermediate voltage which is adjustable by moving the ring-shaped terminal along the varistor.
