Summary:The main methods of research of reliability of low-voltage electric devices are presented; results of studying the characteristics defining their working capacity are given. The laws determining parameter changes of a refusal stream, the failure rate of low-voltage switching devices and 0,4 kV cable lines, as well as their confidential intervals on the basis of processing statistical information are defined. The obtained data can be used at reliability assessment of equipment of the shop low-voltage networks and at drawing up schedules of preventive maintenance, surveys and programs for equipment replacement. The received dependences allow predicting change of technical condition of electric network equipment, timely measures and carrying out surveys and scheduled preventive maintenance of the corresponding equipment at correct times.
