introduction
JJF 1071 "national calibration specifications write rules metering", JJF 1001 "common measurement terms and definitions" and
JJF 1059.1 "Evaluation and Expression of Uncertainty in Measurement" together constitute the basic support system calibration specification revision work
Column specification.
This specification compared with JJF 1067-2000, 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 multi-disk 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).

4.1 Precision inductive voltage divider
Precision inductive voltage divider is divided into single-disc and multi disc induction inductive voltage divider divider categories. With conduct their frequency voltage ratio standard
Associate the auto-sensing voltage divider commonly used two-stage 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).

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.
