This specification compared with JJF 10672000, in addition to editorial changes, the major technical changes are as follows.  Improved traceability series voltage summing circuit (see 4.3);  Modified frequency voltage ratio standard in measurement accuracy means the accuracy of the correction value based on the ratio of the main criteria Requirements defined limits and error list (see section 5.1, Table 1);  Modified frequency voltage ratio standard means a standard appliance needs 1.5 times the power frequency voltage withstand without damage Requirements (see 5.4.1);  Modify the multidisk error representation inductive voltage divider, and the elimination of more than half of the divider plate induction whole school Registration (see 4.1 and 7.2.3.2). Frequency voltage proportional Standards at 1 Scope This specification is applicable to precision inductive voltage divider and precision voltage transformerbased standard, a reference potential method and strings United voltage addition as the working methods traceable calibration frequency voltage ratio standard equipment. 2. References This specification refers to the following documents. JJG3142010 measuring voltage transformer GB/T 16927.1 Highvoltage test techniques  Part 1. General definitions and test requirements For dated references, only the edition applies to the specification; undated reference documents Member, the latest edition (including any amendments) applies to this specification. 3 terminology and units of measurement The following terms and definitions apply to this specification. 3.1 Lifting deteriorated variationbetweenvoltageriseandfal Frequency voltage ratio standard device in the voltage rise and voltage drop during the same percentage error of the voltage measurement results Fruit of the difference. 4 Overview 4.1 Precision inductive voltage divider Precision inductive voltage divider is divided into singledisc and multi disc induction inductive voltage divider divider categories. With conduct their frequency voltage ratio standard Associate the autosensing voltage divider commonly used twostage structure, the electrical schematic shown in Figure 1 and Figure 2. To reduce the lead Drop Error, exciting winding W1 and W2 winding ratio should use the respective connecting wires with a voltage terminal. As power frequency voltage ratio standard is used, the induced voltage divider ratio error as defined by the formula (1). = (U 2U 1/Kn)/U 2 = ΔU 2/U twenty one) Where. Kn  induction nominal voltage divider ratio, and inductive voltage divider ratio to deliver basic reciprocal relationship; 1  inductive voltage divider input voltage, V; 2  inductive voltage divider output open circuit voltage, V. NOTE. If you use need to be converted to an error ratio of the input side, should be the appropriate instructions in the calibration results. ......
