Introduction

This specification is based on the national measurement technical specifications JJF 1071-2010 "national measurement calibration standard preparation rules" JJF 1001-2011 "General Metrology Terms and Definitions" and JJF 1059.1-2012 "Measurement Uncertainty Assessment and Table Show "the preparation. This specification is the first release. Code for calibration of variable frequency power analyzers

1 Scope

This specification applies to the frequency range of 5Hz ~ 1500Hz frequency conversion power analyzer at a specific frequency voltage, Current, power, phase calibration.

2 reference file

This specification refers to the following documents. AC Digital Power Meter JJG780-1992 Digital Multimeter. GB/T 13978-2008 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

Frequency conversion power analyzer is composed of sampling circuit, control unit, transmission unit and digital processor composed of variable frequency The flow signal is the instrument for the measurement and analysis. The analyzer adopts the sampling circuit to adopt the measured voltage and current signal Sample, RMS calculation and Fourier analysis, showing the measured signal voltage, current, power factor (phase), power And other parameters, the principle shown in Figure 1. Variable frequency power analyzer (hereinafter referred to as analyzer) usually includes power analysis Instrument, voltage/current analyzer and so on. Figure 1 Schematic diagram of the analyzer

4 measurement characteristics

4.1 Voltage Measuring range. 50mV ~ 10kV Maximum permissible error. ± (0.05% ~ 2%) 4.2 Current Measuring range. 10mA ~ 1000A Maximum permissible error. ± (0.05% ~ 2%) 4.3 phase Measuring range. 0 ° ~ 360 ° Maximum permissible error. ± (0.01 ° ~ 0.5 °)
