Definitions

  • the invention relates to a monitoring arrangement for electrical equipment according to the preamble of claim 1 and a monitoring system according to the preamble of claim 20.
  • Surge arresters are used in the medium-voltage and high-voltage range in order to safely divert so-called overvoltages, i.e. voltages far above the nominal voltages intended during operation, to earth. This causes damage to equipment such as Transformers avoided.
  • a surge arrester for high voltage can be placed on an overhead line and in the event of a lightning strike or short circuit, it can discharge impermissibly high currents to earth.
  • Surge arresters usually contain so-called varistors ("variable resistors”), i.e. electrical resistors whose electrical resistance value is very high up to a design-related threshold voltage and greatly reduced above the threshold voltage, so that the surge arrester becomes a good electrical conductor.
  • varistors electrical resistors whose electrical resistance value is very high up to a design-related threshold voltage and greatly reduced above the threshold voltage, so that the surge arrester becomes a good electrical conductor.
  • varistors i.e. electrical resistors whose electrical resistance value is very high up to a design-related threshold voltage and greatly reduced above the threshold voltage, so that the surge arrester becomes a good electrical conductor.
  • the surge arrester is hardly conductive during normal operation, so that only a small leakage current flows to earth. In the event of an overvoltage, however, a high leakage current flows.
  • the monitoring device "ACM advanced - Arrester Condition Monitoring” for monitoring surge arresters. It is connected to the underground cable of an arrester and has solar cells for power supply.
  • the device has a digital display device and a communication device that is designed for radio transmission of measurement data in the immediate vicinity Overvoltage impulses are recorded by sensors with regard to a maximum amplitude, pulse width and energy input and provided with a time stamp. Furthermore, the total leakage current is recorded (3rd harmonic) and the total energy absorption of the arrester is determined. The device saves the measured values internally in a data memory so that later information can be obtained from the history of the derivation processes.
  • the object of the invention is to specify a monitoring arrangement with which an accurate remote monitoring of electrical equipment is made possible in a comparatively comprehensive and efficient manner.
  • the invention solves this problem by means of a monitoring arrangement according to claim 1.
