摘要：
Method and device for monitoring the status of a sheath voltage arrester of a cable system, a verification signal being supplied to a measuring loop which comprises the sheath voltage arrester and a measurement signal which is subsequently produced in accordance with the frequency-dependent impedance of the sheath voltage arrester being measured at the measuring loop in order to establish the status of the sheath voltage arrester by evaluating the measurement signal.
