Problems solved by technology

[0003] During the daily operation of the equipment, the power supply capacity of the power supply (transformer) is too small, the low-voltage power supply line is too long, and the cross-section of the low-voltage power supply line is too small, etc., which will cause the voltage fluctuation of the equipment and affect the normal operation of the equipment. The various voltages of the equipment are effectively monitored, and it is difficult to ensure the long-term stability of the equipment voltage

Description

technical field [0001] The invention relates to the technical field of voltage monitoring, in particular to an online overvoltage monitoring system of a power system. Background technique [0002] Voltage, also known as potential difference or potential difference, is a physical quantity that measures the energy difference generated by a unit charge in an electrostatic field due to different potentials. , the direction of the voltage is defined as the direction from high potential to low potential. The international unit system for voltage is volts (referred to as volts), and commonly used units include millivolts, microvolts, and kilovolts. This concept is similar to "water pressure" caused by high and low water levels. It should be pointed out that the term "voltage" is generally only used in circuits, while "potential difference" and "potential difference" are generally used in all electrical phenomena. [0003] During the daily operation of the equipment, the power su...
