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).
Step-down transmission substations are located at switching points in an electrical grid. They connect different parts of a grid and are a source for subtransmission lines or distribution lines. The step-down substation can change the transmission voltage to a subtransmission voltage, usually 69 kV. The subtransmission voltage lines can then serve as a source to distribution substations. Sometimes, power is tapped from the subtransmission line for use in an industrial facility along the way.
