OPTIMAL AMOUNT OF INVESTMENT IN ORDER TO ARCHIVE MAXIMUM QUALITY WITHIN DISTRIBUTION POWER SYSTEM
KOMUNALNA ENERGETIKA / POWER ENGINERING, 12
The present article deals with quality of electrical energy within distribution power system connected to the cost. Two objective functions were determined: for hybrid quality index Q and costs C. The proposed two criteria of optimization can be used to calculate the optimal amount of investment in order to archive maximum quality.

Challenges of on-Line Condition Monitoring of Hydraulic Oils
KOMUNALNA ENERGETIKA / POWER ENGINERING, 137
Ensuring adequate quality of hydraulic oil and planning its change is crucial for a stable and smooth operation of many industrial machines. The best reliability can certainly be provided by using continuous monitoring of hydraulic oils, which is usually carried out remotely by means of modern online sensors.
Nevertheless, the development and implementation of such a system represents a unique challenge, since the measurement of the oil condition is much more complicated than measuring usual operating parameters, such as pressure or temperature.
