Introduction

This specification is based on JJF 1071-2010 "national measurement calibration standard preparation rules", JJF 1001-2011 "pass Metrological terms and definitions "and JJF 1059.1-2012" Measurement Uncertainty Assessment and Representation ". In this specification, the measurement of variable frequency power transmitter in the practical application of the measurement object is usually a complex waveform of the electricity Voltage, current signal, the output can be DC, AC and digital signals. Such transmitters have a wide band of measurements Capability, mainly used for variable frequency drive in the power measurement. This specification is the first release. Standard Specification for Variable Frequency Electricity Transmitter for Measurement

1 Scope

This specification applies to the input for the AC voltage or current signal, the output is AC, DC analog signal or digital signal Of the measured frequency of the voltage transmitter in the (5 ~ 1500) Hz at a specific frequency of voltage, current, delay phase shift of the school quasi. This specification does not apply to calibrations of measuring transmitters operating only at high frequency or fixed frequency operation.

2 reference file

This specification refers to the following documents. JJG126-1995 AC power conversion for the DC power electrical measurement transmitter GB/T 13850 AC power conversion to analog or digital signal of the electrical measurement transmitter For dated references, only the dated edition applies to this specification; references that are not dated , The latest version (including all modifications) applies to this specification.

3 Overview

Measurement of variable frequency power transmitter is a certain frequency range and according to a specific law changes in the voltage or current letter Is converted into an instrument that is measured as a function of the relationship signal, and its output is all the features or parts that contain the input power Sub-characteristic information exchange, DC analog signal or digital signal. Measuring variable frequency power transmitter is usually composed of sensors, converters and transmission units, etc., the input power through The sensor is converted into a small power signal, converted by the converter through the transmission unit for secondary equipment, the principle shown in Figure 1 As shown. Measurement of variable frequency power transmitter (hereinafter referred to as the transmitter) in accordance with the input power can be divided into voltage transmitter, power Flow transmitter; according to the output signal type can be divided into analog output transmitter and digital transmitter; analog output transmitter The signal type can be divided into AC voltage output, AC current output, DC voltage output, DC current output. figure 1
