Introduction

This regulation is based on JJF1001-2011 "General Measurement Terms and Definitions", JJF1002-2010 "National Measurement The rules for the preparation of verification procedures are formulated. This regulation amends JJG 588-1996, compared with JJG 588-1996, except for editorial changes. The technical changes are as follows. --- Modify the representation of the basic error of "measurement performance" (see 5.1); --- "Measuring performance" increases the need for repeatability (see 5.3); --- Increase the standard wave source time parameters (see 7.1.4); --- Removed the content of the original procedure using the comparative method to verify the basic error; ---Modified the requirements of the "basic error" verification voltage point and the number of measurements (see 7.2.2.4); --- Removed the original procedure "basic error" plus test requirements. The previous versions of this procedure were released as follows. ---JJG 588-1996. Impact peak voltmeter verification procedure

1 Scope

This procedure is applicable to the first verification of the digital impact peak voltmeter with a measurement range of ±(100~1600)V. Subsequent verification and in-use inspection.

2 reference files

This procedure refers to the following documents. GB/T 16896.1 High voltage impulse measuring instruments and software Part 1 requirements for instruments GB/T 16927.1 High Voltage Test Technique Part 1. General Definitions and Test Requirements For dated references, only the dated version applies to this Code; any undated quotation The latest version (including all amendments) applies to this procedure.

3 terms

The terms and definitions established in GB/T 16896.1 and GB/T 16927.1 apply to this standard. 3.1 Impact peak voltmeter impulseIvoltometer An instrument capable of measuring the peak value of the surge voltage. There should be no short-term overshoot or short time near the peak of the surge voltage. High frequency oscillation. [GB/T 16896.1-20053.1.3]

4 Overview

The digital impulse peak voltmeter (hereinafter referred to as the peak table) is an instrument for measuring the peak value of the surge voltage. when using it, The peak meter is connected to the secondary voltage output of the surge voltage divider through a transmission cable to measure the voltage of the surge voltage divider. Output voltage peak. By inputting the voltage division ratio of the surge voltage divider on the peak surface plate, the peak table display unit can The primary voltage peak applied to the surge voltage divider is directly displayed. The peak table is generally composed of a secondary attenuator, A/D The acquisition conversion unit and the display device are composed.

5 Metrological performance requirements

5.1 Basic error The maximum allowable error of the peak voltage of the peak meter is as shown in equation (1). Δ=±(a%Ux b%Um) (1) In the formula. Δ---maximum allowable error, V or kV; a---the error coefficient related to the reading value; b---the error coefficient related to the range; Ux---the reading value of the peak table to be inspected, V or kV; ......
