To compute the complete loss of voltage in the television network to optimize the maximum voltage regulation

The Complete loss of voltage in the network was calculated there is no voltage in the network for more than 40 seconds due to interruptions in the power supply connections. Sag (a short-term decrease in the voltage in the network to a value less than 80% of the nominal value for 1 period (1/50 second) as a result of turning on powerful loads, manifests itself externally as flickering of lighting lamps) and surges (short-term voltage in the network more than 110% for more than 1 period increases (1/50 second); appears when large load is switched off, flickering of external lighting) voltages of varying duration (common in large cities). The high frequency noise of radio frequency interference of electromagnetic or other origin. In this paper, To compute the complete loss of voltage in the television network to optimize the maximum voltage regulation. This resulting from the operation of powerful high frequency devices, communication equipment. High voltage waves - short-term voltage pulses up to 6000V and duration up to 10 ms; Appears during thunderstorms, as a result of static electricity, due to the spark of switches, there are no external manifestations. Frequency run-out - a change in frequency of 3 or more Hz from the nominal (50 Hz), which appears during transient operation of the power source, does not appear externally.
