This standard is based on the International Electrotechnical Commission IEC60255-16:1982 "Electrical relays Part 16: Impedance measuring relays" and is equivalent to it in technical content. The writing rules are based on GB1.1-1993. In the process of writing this standard, based on the actual situation in China, without losing the principle of equivalent adoption, the recommended content of 15.4 (test conditions) was changed to "subordinate standard provisions". For ease of understanding, this standard retains the preamble in IEC 60255-16. Since IFC255-6 (1978) and IFC255-6A (1980) have been revised to IFC255-6 (1988) Electrical relays Part 16: Regulated relays and protective devices in 1988, the references to IFC255-6 (1978) and IEC255-6A (1980) in this standard should also be changed to IFC255-6 (1988) Electrical relays Part 6: Regulated relays and protective devices. It has been converted into national standards GB4598.3-93, GB/T14047-93 and GB/T14598.1-93, so a chapter "reference extension standard" is added in this standard. In view of the change from JEC255-16 to JEC60255-16, the new number JEC60255-16 is adopted in the standard. However, in order to ensure the equivalence of deep use, the original abbreviations of other 255 series standards mentioned in the original JEC255-16 will be retained. Considering the anti-interference requirements of static products, Chapter 14 "Interference Withstand Capability" is added to this standard, including 14.1 Withstand the ability to withstand complex pulse group interference: 14.2 Withstand the ability to withstand the micro-electric interference: 14 .3 Ability to withstand interference from external sources: 14.4 Ability to withstand rapid interference. In addition, the corresponding anti-interference test (Chapter 19) is added. This standard shall be implemented from January 1, 2001. This standard is proposed and coordinated by the National Technical Committee for Standardization of Measuring Relays and Protection Equipment. The drafting unit of this standard: Xulu Relay Research Institute. The main drafters of this standard: Li Shaofeng, Zhao Zhihua, Cai Jianqi. JB/T102202000
1 Formal resolutions or agreements on technical issues are often made by all national committees and departments that are particularly concerned about the issue, and the technical committees involved express the international consensus on the issues involved as much as possible. 2 These resolutions and agreements are based on The form of recommended standards is provided for reference and is recognized by national committees in this sense. 3 In order to promote international unification, IEC has indicated that the responsible national committees should adopt the contents of IEC recommended standards as their national standards within the scope of application permitted by domestic conditions. If there are any inconsistencies between IEC recommended standards and corresponding national regulations, they should be clearly stated in the national regulations as much as possible.

This standard was prepared by the 41st Technical Committee of EC (Electrical Maintenance Equipment) [Measurement of Electrical Equipment Protection Devices]
The draft of this standard was prepared in Nice in 1976, Milan and Milan in 1977. The meeting held in Jinglexingji in 1979 was discussed as the result of the discussion at the next meeting: Document 41B (Central Office) No. 24 was submitted to the National Committee for voting in April and June 1980. The following countries also voted in favor of publication: Austria Belgium Ireland Israel Romania South Africa (Republic of Turkey) Yugoslavia Publications of Technical Committee 41 are classified as follows: First level: General standards Second level: General standards related in whole or in part to a large category of relays. Third level: Technical specifications for components of a group of relays that are applicable in whole or in part to a group of relays. This standard is a third level publication.

These relays form a branch of multi-input voltage measuring relays as defined in IEC publication 255-6 Electrical relays Part 6: Measuring relays and protection devices. This standard specifies the test methods and the methods of demonstrating the characteristics and performance of relays. It includes relays with impedance as the input voltage pulse and its operating characteristics are set at RX level. This standard is applicable to relays with a time limit or it is a load-operated device. It does not include insulators within the scope of IEC 255-12 Electrical relays Part 12: Devices with two input voltages and power relays. All tests in this standard are for test purposes only. This standard applies to new devices.
! The term "relay" includes all devices that are necessary to verify the operation of the relay and the components that are tested together with the relay. 2. The impedance measurement can be a single quantity or a composite quantity of two currents (or more currents), such as the sum of two phase-to-earth voltages, the sum of compensation currents, etc. In order to obtain a specific performance characteristic, the micro-quantity can be a composite quantity or the energy can be introduced into the micro-excitation device. 2 Reference standards The following standards contain clauses that are incorporated into this standard by reference.
