The possibilities of compensating the electric field strength of external insulation of high-voltage gas-filled current transformers
There have been proposed methods of intensity distribution regulation along external isolator of gas-filled current transformers. In the offered methods the column from sequentially connected insulators is considered, th...
Requirements for contact materials of switching devices
It is proposed to move from use in the construction of high-current electrical apparatus of copper alloys as electrical contact materials to powder materials. An analysis of the composition of the powder material is pres...
Analysis of the influence of the magnetic permeability of the steel reinforced concrete structures on the level of the geomagnetic field inside premises
It is shown that the use in the construction of standard reinforcing bars leads to a dangerous weakening of the geomagnetic field on the premises. The requirements for the magnetic permeability "weakly magnetic" structur...
Step voltage converter as an alternative source for magnetic pulse metal working systems and induction heating systems
The use of preliminary induction heating of the working zone of magnetic-pulse sheet metals working can improve its efficiency and expand the existing range of technological operations for contactless metal working. Inte...
Reduction of electrical machines and apparatuses production costs by using business process outsourcing
In the article the actual problem of electrical industry enterprises to reduce production costs. Development of measures to reduce production costs for enterprises is an urgent problem for many businesses the electrical...
