Abstract:
Inverters (AC-DC-AC) with frequency 50 - 130 Hz are used for dimming of lamps in street and tunnel lighting systems. Their output voltage has shape different from sinusoidal. The latter as well as the usage of discharge lamps leads to increasing the level of high harmonics of the current in the supply lines. The paper describes the method for calculating voltage losses from the inverter up to luminaries with high pressure discharge lamps and shows exemplary calculations.
