Summary: This standard applies to a certain frequency range to provide an accurate number of the AC voltage at the output load ratio and can be ignored under the conditions of use of the induction voltage divider. Note 1: A transformer is defined as the purpose of measuring the load for supplying power to a device, in IEC 60186: voltage transformer described. Note 2: In some multi-disk induction voltage divider, the last one dial (least significant bit) of the adjustment line is resistive. This standard does not apply to inductive voltage divider used in conjunction with any auxiliary equipment.

Foreword

This standard is equivalent to using the International Electrotechnical Commission standard IEC 60618.1997 "inductive voltage divider" (in English), its technical content and structure And IEC 60618.1997 are identical. This standard replaces GB/T 9091-1988 "inductive voltage divider." This standard and GB/T 9091-1988 "inductive voltage divider" than major changes are as follows. --- Information and content of the flag, the deletion of the original test voltage flag, flag increases the level of pollution and other requirements. Appendix A of this standard is a normative appendix. The standard proposed by China Machinery Industry Federation. This standard by the National Electrical Instrument Standardization Technical Committee (SAC/TC104) centralized. This standard was drafted. Shanghai Instrument Research Institute. The main drafters of this standard. Zhangyin Fu, Dong Yafeng. This standard replaces the standards previously issued as follows. --- GB/T 9091-1988.

1 Scope

This standard applies to provide several accurate AC voltage ratio within a certain frequency range and output load negligible Inductive voltage divider used condition. Note 1. refers to the transformer to the load measuring purposes and to provide a means of electrical energy, in IEC 60186. narrative Voltage Transformer. Note 2. In some multi-disk inductive voltage divider, which last a dial (least significant bit) of the adjustment line is resistive. This standard does not apply to any auxiliary equipment used in conjunction with the inductive voltage divider.

2 Terms and Definitions

The following terms and definitions apply to this standard. 2.1 Means one or more transformers are interconnected composed of switches or other means so that the output voltage equal to the input voltage of the device The proportion of a selected value. Note 1. "IVD" including one called "precision autotransformer", "decimal transformer voltage divider," "inductive voltage divider" and "transformer ratio" means. Note 2. The main characteristics of inductive voltage divider is given in Appendix A. Note 3. Some inductive voltage divider using a separate auxiliary winding (field winding) provides magnetic core losses and after use can greatly improve the measurement of the coil windings Input impedance and inductive voltage divider to reduce the error, this divider is called "two inductive voltage divider." 2.2 Open circuit output voltage sensing divider complex amount (relative amount) with its input voltage complex amount (relative amount) ratio. 2.2.1 Open-circuit output voltage and input voltage ratio by a stepping switch or other selection methods rate indicated. Note. This is a ratio of the number of readings by the instrument panel or a similar indicator was read. 2.3 Predetermined accuracy inductive voltage divider is used rather than the reference value. Inductive voltage divider reference value is 1, which is equivalent to (or should correspond) open-circuit output voltage is equal to the ratio of the input voltage is passed. 2.4 Passed by the nominal rate minus the actual transfer rate get. Note 1. When the transfer is indicated by the ratio error than the reference value, since the reference value is 1, so that its value remains constant. Transfer ratio error molded form mathematically expressed as follows. Note 3. The pass percentage ratio error mode available reference value (%), or by a reference value in parts per million (ppm), or by a proportion of the value of the reference value Scientific notation indicates (see Chapters 3 and Table 1).
