Abstract
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.
Claims20
A device for monitoring a sheath voltage arrester of a cable system, comprising:
- a verification signal source for producing a verification signal which is to be supplied to a measuring loop which comprises the sheath voltage arrester, and
- a measuring device for detecting a measurement signal which is measured at the measuring loop and which is dependent on a frequency-dependent impedance of the sheath voltage arrester in order to establish a status of the sheath voltage arrester by evaluating the measurement signal.
A method for monitoring a sheath voltage arrester of a cable system comprising the steps of:
- supplying a verification signal to a measuring loop which comprises the sheath voltage arrester, and
- detecting a measurement signal which is measured at the measuring loop and which is dependent on a frequency-dependent impedance of the sheath voltage arrester in order to establish a status of the sheath voltage arrester by evaluating the measurement signal.
A device for monitoring a sheath voltage arrester of a cable system, comprising:
- a verification signal source for producing a verification signal which is to be supplied to a measuring loop which comprises the sheath voltage arrester,
- the verification signal source being coupled to a cable system in such a manner that the verification signal is supplied to a shield system of a cable sleeve to which the sheath voltage arrester is fitted, a measuring device for detecting a measurement signal which is measured at the measuring loop and which is dependent on a frequency-dependent impedance of the sheath voltage arrester in order to establish a status of the sheath voltage arrester by evaluating the measurement signal,
- a sensor for reading the measurement signal at the measuring loop being provided in proximity to the sheath voltage arrester, and
- the verification signal being supplied by the sheath voltage arrester to the measuring loop in a galvanically decoupled manner and the measurement signal being measured at the measuring loop in a galvanically decoupled state.
