霍尔传感器的角差对功率测量的影响
Influence of Holzer Sensors’Angle Difference on Power Measurement
摘要
Abstract
Angle differenceis an important part oftransformer accuracy performance,and is one of the mainfactors influ-encing power measurement accuracy. However,in power measurement such asinverter motors,transducers and invert-ers,the angle errorof the sensoris often ignored,because the nominalangle errors of widely used Holzervoltage and cur-rent sensorsarenot givenin general. Through a large numberof testsbased onLEM’s LV100-4000 typeof Holzervoltage sensor,thephase erroris analyzed and calculated. The result is basically consistent with the angle difference derived fromthe nominalrise timeof the sensor. Based on the result,the angle difference estimation formula for theHolzervoltage sensoris presented,and the referencevalue ofangledifference for common Holzervoltage sensors is given according to the formula.关键词
