Abstract

The invention relates to a metering working voltage drop automatic test platform and voltage drop modes. The metering working voltage drop automatic test platform comprises a voltage drop experimental device, a PC, a communication interface, a communication network, a single-phase meter, a three-phase meter, a collector and a concentrator. The metering working voltage drop modes comprise the linear drop mode, the stepped drop mode, the instant drop mode and the voltage interruption mode. The four representative drop modes are designed so that the metering of an electric energy meter is in an up-and-down power-down state, manual misjudgement and repeated test work are reduced, the test platform never feels tired, off-duty time is made full use of, and the meter check efficiency is improved.

Description

technical field [0001] The invention relates to an automatic test platform for meter working voltage drop and a voltage drop mode. Background technique [0002] Power quality is not only related to the safe and economical operation of the power grid, but also affects the normal work of large and small power loads. With the development of modern industrial technology, the grid structure has become increasingly complex; at the same time, many power-sensitive devices are used in production, and these devices have high requirements for power quality, and new power quality problems follow. Relevant research data show that the voltage drop problem is the power quality problem with the highest occurrence rate and the most serious loss among these power quality problems. Therefore, people pay more attention to voltage sag than other power quality issues. [0003] Especially in recent years, power-sensitive equipment based on computer control has been widely used in industrial prod...
