Introduction

JJF1002 "Rules for Writing National Metrology Verification Regulations", JJF1001 "General Metrology Terms and Definitions" and JJF1059.1 "Assessment and Expression of Measurement Uncertainty" together constitute the basic series supporting the revision of this regulation specification. This regulation adopts GB/T 32191 "leakage current tester", GB 4793.1 "measurement, control and laboratory Safety requirements for electrical equipment Part 1.General requirements "measurement network specified. This regulation replaces the non-medical leakage current tester part of JJG 843-2007 "Leakage Current Tester". and Compared with the part of non-medical leakage current tester in JJG 843-2007, the main technical changes are as follows. --- Added terms; --- Modify the measurement network evaluation method; ---According to different measurement networks, the DC input resistance value and its maximum allowable error are specified; ---According to GB/T 32191, use the input impedance and leakage current within the frequency range of 20Hz~1MHz Indication error on electrical burn measurement network, sense/reaction current measurement network, get rid of current measurement network and wet contact current measurement network for evaluation; --- Modified the verification method of leakage current indication error; --- Added Appendix A, which introduces the various measurement networks and their characteristic values specified in this regulation. The release status of previous versions of this regulation is as follows. ---JJG 843-2007; ---JJG 843-1993. Verification Regulations for Leakage Current Tester

1 Scope

This regulation applies to leakage current testers and touch current testers with one or more measurement networks for the first time. Verification, follow-up verification and in-use inspection. This regulation does not apply to the verification of medical leakage current testers and medical contact current testers, nor does it apply to Verification of breakdown current of voltage tester, component leakage current tester and leakage protection tester. Note. See Appendix A for the measurement network applicable to this regulation.

GB 4793.1 Safety requirements for electrical equipment for measurement, control and laboratory use Part 1.General requirements GB/T 12113 Measurement methods of touch current and protective conductor current GB/T 32191 Leakage Current Tester For dated references, only the dated version applies to this regulation; for undated references document, its latest version (including all amendments) applies to this regulation.

3 terms

3.1 Measuring network measuring network A circuit device used to simulate the impedance characteristics of the human body, usually a circuit network composed of resistors and capacitors. Measure the output voltage of the network (or the leakage current indication value of the leakage current tester and the contact current tester) and relationship between inputs.

4 Overview

Leakage current tester, contact current tester (hereinafter referred to as tester), used to measure the Under single-fault conditions, the touch current is measured through the measurement network when a human or animal touches electrical equipment. The tester is mainly composed of measurement network, signal amplification, signal processing, current indication module, working power state switching Switch, sound and light alarm and other components. The tester can be divided into digital type and pointer type according to the display mode. The measurement and indication module of the test voltage, and some testers have their own test power supply inside. Measurement network simulation for testers The impedance characteristics of the human body and the characteristics of electric shock response to high-frequency currents are studied. In order to meet the requirements of different equipment safety standards, the test Testers often have multiple measurement networks.

5 Metering performance requirements

5.1 Accuracy class and maximum permissible error The accuracy level of the tester is rated according to the maximum allowable error of the leakage current at DC/power frequency of 50Hz, ......
