Modelling Characteristics of Reliability Low-Voltage Switching Devices on the Basis of Random Checks on the Example of Contactors

One of authentic valuation methods of quality of functioning of the equipment is carrying out observations of their work during the entire period of operation. At fixation of operating state or failure there are situations when some part of the equipment did not refuse during observation. At the same time statistical information processing on the basis of random checks is carried out.
