Introduction

This procedure based on JJF1002-2010 "national verification procedures write rules" establishment. This procedure is based on GB/T 17215.211-2006 "AC measuring equipment General requirements, tests and test strips Section member 11. measuring equipment ", GB/T 17215.321-2008" special measuring equipment to AC Seeking Part 21. Static meters for active energy (level 1 and level 2) ", GB/T 17215.322-2008" AC Measuring equipment - Specific requirements Part 22. Static meters for active energy (0.2S and 0.5S grade level " GB/T 17215.323-2008 "AC measuring equipment - Specific requirements - Part 23. Static reactive power meter (Level 2 and 3) "as the basis for JJG 596-1999" electronic meter, "subject to revisions. And JJG 596- 1999 version compared to this Regulation except editorial changes, the main changes in the technical part as follows. --- Procedure name from the original electronic energy meter to electronic AC meter; --- Apply only to test the installation of energy, electricity and does not apply to standard test meter, digital meter Menu site inspection; --- Clear 0.2 and 0.5 for the class 0.2S and 0.5S level of class 0.2S, 0.5S level meter is only applicable For active energy meter access by the transformer; --- Increased levels 2 and 3 and the corresponding reactive power meter technical requirements; --- Increasing the difference between the requirements of error of unbalanced load and balance the load; --- Increased day project timing errors. The previous versions of the release JJG 596-1999 case. --- JJG 596-1989. Electronic AC electricity meter testing procedures

1 Scope

The order applies to the reference frequency of 50Hz or 60Hz single-phase, three-phase electronic (static) AC power meter (Referred to as the electronic energy meter or meter) of the initial verification, subsequent verification. For having other functions of the electronic energy meter, which is the same verification procedure of the project implementation. This procedure does not apply to electro-mechanical (induction system) AC power meter, the standard power meter, digital power meter (electrical test Pressure field, the current digital meter) and meter verification test. 2. References This procedure refers to the following documents. JJG 597-2005 AC power meter testing equipment GB/T 17215.352-2009 AC measuring equipment - Specific requirements - Part 52. Symbols For dated references, only the dated edition applies to this procedure; undated reference documents Member, the latest edition (including any amendments) applies to this procedure.

3 Overview

Electronic devices composed of AC power measurement circuit table called electronic AC power meter, the current and voltage is applied The solid state (electronic) device, proportional with the power generated within a certain time and the. Because it is different from electromechanical (flu Should the Department) AC power meter has a rotating element, it is also known as static AC power meter. Electronic single-phase energy meter Principle block diagram shown in Figure 1. Principle block diagram of the electronic structure of single-phase energy meter For three-phase electronic energy meter, each phase voltage and current sampling circuit and the multiplier with electronic single-phase energy meter Same, but before the P/F converter summing circuit to be added, the multiplier output signals of the respective phases to the frequency divider are added. frequency conversion.
