Heilongjiang 20,000 Electric Energy Meters Complete High Temperature Test

From July 11 to 18, Heihe Electric Power Co., Ltd. Mohe Low Temperature Test Site successfully completed the limit high temperature test of 20,000 test meters. A total of 3,780 test data were collected.

It is understood that due to the special geographic location and climatic conditions of Daxing'anling, the applied energy meter is a power meter that can work normally under low temperature conditions. In 2008, the Heilongjiang company established the first low-temperature test site in the Mohe Power Supply Zone of the Daxinganling Electric Power Bureau, and tested the measurement errors of the electric energy meter under low-temperature, high-temperature, and normal-temperature environments, respectively. Among them, the test average temperature of the low-temperature environment is minus 43.19 degrees Celsius, the average temperature at high temperatures is 37.55 degrees Celsius, and the room temperature is 22 degrees Celsius.

During the test period, the functions of the test power meter checked were basically normal, the measurement error was within the specified range, and the number of acquisitions was the same as the number of indications. At present, Heilongjiang Electric Power Institute is scientifically analyzing and summarizing relevant data, and initially determines that the electronic tables that are widely used in the Greater Khingan Range can withstand temperatures of minus 47 degrees Celsius to 55 degrees Celsius.
