Introduction

This specification is based on JJF 1071-2010 "national measurement calibration standard preparation rules" preparation. This specification is the first release. Calibration specification for volt - ampere characteristic tester of current transformer

1 Scope

This specification applies to the current transformer volt-ampere characteristic tester calibration, also applies to the current transformer with volt Sexual function of the test instrument calibration.

2 reference file

This specification refers to the following documents. Current Transformer for Measuring JJG313-2010 Transformers - Part 2. Supplementary technical requirements for current transformers GB/T Guide for test of transformers - Part 1. Current transformers GB/T 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 terminology

3.1 Volt-Amperecharacteristmeter Test equipment with volt-ampere characteristic measurement function of current transformer. 3.2 excitation current excitationcurrent Current transformer primary winding and other winding open circuit, the rated frequency of the sine wave voltage applied to the secondary terminal Through the current value of the secondary winding. Note. The steady-state protection current transformer excitation current is expressed by the root mean value; transient protection current transformer current excitation Using a peak representation. 3.3 rated inflection potential ratedkneepointe.mf When all the other terminals of the transformer are open, the rated frequency of the sine wave applied to the secondary terminal The root value of the field is increased by no more than 50% when the value is increased by 10%. Note. The actual inflection point potential is not less than the rated inflection point potential. 3.4 excitation characteristics When the current transformer primary winding and other windings open, applied to the current transformer secondary winding terminal The relationship between the square root value and the excitation current is expressed by a graph or a table. Note. These values are covered by a range sufficient to determine the excitation characteristics from the low excitation value up to 1.1 times the inflection point potential. 3.5 volt-ampere characteristics reference standard V-Icharacteristicstandardcurrenttransformer Volt characteristic The standard current transformer used in the calibration of the tester, whose excitation characteristic curve is calibrated and the performance stable.

4 Overview

Volt-ampere characteristic is a current transformer secondary winding sine wave voltage and excitation current value of the characteristic curve, commonly used
