Monitoring of the technical state of overhead lines the basic instrument for determination of remaining lifetime S.. Davydkin, branch of JSC Engineering center UES firm ORGRES The main task of inspection of overhead lines is an estimation of the technical state of lines for the purpose of determination of the possibility of their further exploitation or necessity of their technical re-equipping, reconstruction, modernization and repair. The main goal is to determine the state of separate elements of overhead line. Key words: overhead lines, monitoring, remaining lifetime, repair.

Smirnov, JSC Sverdlovsky plant of current transformers , . , , . , . ? , . (). : , , . In connection with equipments updating there is an active replacement of old current transformers on new ones which comply with modern requirements. With the increase of voltage class increases the complexity of transformers construction, dramatically increases the expenditure of electrotechnical steel, copper and insulating materials. Consequently dramatically increases the cost of equipment. Is there a possibility to solve this problem? Undoubtedly there is, due to application of build-in current transformers. Key words: current transformer, replacement, magnetic conductor.

Samorodov, branch of State Educational Institution of Higher Professional Education Ufa Sate Petroleum Technological University - , , . , . , - . , . : , , - . At the present moment there are a lot of methods of diagnostics of electric drives of pump and compressor equipment but not all of them can be applied for diagnostics of explosion-proof drives because of the risk of explosion at site. An article suggests the method of diagnostics based on spectral analysis of current and voltage of the motor of electric drive. Applying this method you can change from scheduled preventive repair of equipment to repair on actual state. Key words: electric drive, lifetime, pump and compressor equipment.
