How to convert power in dBm to dBW. The power in dBW (P (dBW)) is equal to 10 raised by the power in dBm (P (dBm)) divided by 10: P (dBW) = P (dBm) - 30.
Step-Voltage Regulators applied in the utilityâs distribution systems are generally medium-voltage mechanical automatic voltage regulators (AVR). It should be noted that there are two distinct types of AC automatic voltage regulators: Medium-voltage (mechanical) and the Low-voltage regulators (mechanical or electronic).
V OLTAGE REGULATORSVS LOAD TAP CHANGERS As a means to regulate substation voltage, some utilities use a substation transformer with a Load Tap Changer (LTC)in one package. However, if one phase of the tap changer fails or requires maintenance, the entire unit is removedfrom service, affecting all three phases.
