Introduction

This specification based JJF 1071-2010 "National Calibration Specifications writing rules", IEC 61340-5-1-1998 "Electronic components protection under static environment General requirements" relevant provisions of the preparation. This specification is the first release. Non-contact electrostatic voltage meter calibration specification

1 Scope

This specification is suitable for measuring the surface voltage not exceeding 20kV non-contact electrostatic voltage measuring instrument (also available Called non-contact electrostatic voltmeter, hereinafter referred to as static tables) calibration. This specification does not apply to contact electrostatic voltage meter calibration.

2 terminology and units of measurement

2.1 Test distance testingdistance In the non-contact measurement, the measured surface and measuring instruments forefront of distance or measuring instruments defined in the specification distance. 2.2 standard plate electrode standardplateelectrode Connecting a standard high voltage power supply, and the edge of the insulation through the metal plate smooth process. In the center of the panel Near the flat surface, parallel to the normal direction of a uniform electrostatic field exists, the voltage on the metal plate can be marked Voltmeter readings or quasi-standard high-voltage power supply is set to determine.

3 Overview

Static table is a method for measuring the electrostatic potential of the surface of the ground equipment. Not in contact with the measured surface situation Under conditions, the use of electric field sensing principle or other principles, the measured voltage value surface. This voltage is infinity or earth A zero reference potential. Static tables are typically by an electric field sensor, a distance indicator, measuring unit, display unit and zero units, have These static tables have a ground terminal. The most common induction electric field sensor capacitive, rotor voltmeter and oscillating capacitor Type and so on. Static table instructions can be divided by distance and distance with a positioning indicator without distance indicator both targeting; press was Shows can be divided into two kinds of pointer and a digital display.

4 Metrological characteristics

4.1 electrostatic voltage basic error The basic error of static table into digital display and basic error pointer display two types of basic error, which is available under the formula One column in the form of representation. Absolute error 4.1.1 Digital Display Δ = ± (a% Ux b% Um) (1) Where. Δ --- basic error limit represents the absolute error, V; a --- error coefficient associated with the reading; ......
