For people in their recent life, electricity is extremely vital. It becomes a primer necessity due to the facts that almost all of our supporting life equipments need electricity to be operated. In addition to its huge benefit, electricity also contains d... see more

The reasons for nuisance tripping of residual current devices (RCD) are analyzed in the article and the affect of many external factors is discussed. Solutions are described for avoiding faulty tripping of an RCD.

The pipelines in the oil and gas industry must be regularly checked for possible corrosion that might cause leakage of oil and gas. Magnetic flux leakage (MFL) technique is a magnetic method of nondestructive testing that is used to detect corrosion and m... see more

The microprocessor device of protection of electric chains of electric motors from short circuit currents, in which switching-off of a short circuit current is carried out before it achieves a shock value, is presented. 

Indonesia is a tropical area with a high intensity of repeating lightning strikes. The voltage is produced by lightning by increasing the presence of sensitive loads. Therefore, lightning can easily worsen the quality of consumer power, even if the genera... see more

Surface currents in coastal waters can be mapped with high frequency radar (HF radar). In this study, month-long surface vector current data from the Upper Gulf, Central Gulf and Lower Gulf of Thailand (UGOT, CGOT, and LGOT, respectively) were analyzed an... see more

In the article the results of experimental research and calculation of wear of current collector system elements of electric transport are presented.

In the article the influence of resistance of secondary winding of the high-voltage measuring current transformer on the error of device of its compensation is considered.

In this paper, a new approach to analysis of the average and rms currents in inverter switching devices and the rms value of the ripple component of inverter input current is presented. The proposed approach is based on the probability with which the inve... see more
