Since the traditional electrical system data monitor equipment has some shortage, such as limited monitoring objects, single monitoring direction, the authors combine computer science Internet technologies with electric power system production process and extend the scope of monitoring system. This paper analyzes the key technology by which the operator monitoring system can be realized, and pu...

Construction and practical use of computerized systems for remote monitoring and diagnostics of electric power facilities are discussed. The structure of information-measuring systems based on an unmanned aerial complex, that are designed to monitor thermal and nuclear power plants’ environment is examined. The structure and algorithms of a multilevel system for monitoring and diagnostics of el...

Outdoor high-voltage equipment is exposed to rain and moisture. Water droplets on the surface of insulators influence negatively the insulating and hydrophobic material properties. The shape of the droplets signifies the state of the aging material. The present paper develops a numerical procedure to determine the three-dimensional shape of water droplets in strong electric fields. That include...

Impulse over-voltages are very common phenomena in electric power systems. Switching impulses are created by switching surges or local faults while lightning impulses are due to lightning strikes to overhead lines. Both impulses can travel as waves in the system, damaging insulation components and equipment. This paper shows that there may well be a reduction in electric field strength of the i...

The computation program of the transient recovery voltages that appears across the terminals of a circuit breaker, after the low inductive current has been interrupted at the disconnecting no load high voltage transformers, using the routines set developed in Matlab is presented. The computation algorithm is based on the peculiarities of operation of the transformer. The computation program has...

The major requirement of implantable biomedical equipment like pacemaker, hearing aid device must have low power consumption and reliability. In order to provide a power to this biomedical equipment’s a new approach is presented in this paper, to extract electric power from heat of the subject or human body. Hereby the surgeries for battery implantation in the subject or human body can be avoid...
