FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.

– 6 – 60255-26 © IEC:2013 INTRODUCTION This part of the IEC 60255 series specifies all of the requirements for electromagnetic compatibility in a single document.
As such, it is considered as an overview document for measuring relays and protection equipment. The detailed test procedures are given in other referenced standards. This part of IEC 60255 does not include the reversal of d.c. power supply polarity test which had been provided in IEC 60255-11, because this is a safety test. This test will be covered by future IEC 60255-27. SIST EN 60255-26:2014

MEASURING RELAYS AND PROTECTION EQUIPMENT –
Part 26: Electromagnetic compatibility requirements
1 Scope 1.1 General This part of the IEC 60255 series is applicable to measuring relays and protection equipment, taking into account combinations of devices to form schemes for power system protection including the control, monitoring, communication and process interface equipment used with those systems. This standard specifies the requirements for electromagnetic compatibility for measuring relays and protection equipment. Tests specified in this standard are not required for equipment not incorporating electronic circuits, for example electromechanical relays. The requirements specified in this standard are applicable to measuring relays and protection equipment in a new condition and all tests specified are type tests only. 1.2 Emission The object of this standard is to specify limits and test methods, for measuring relays and protection equipment in relation to electromagnetic emissions which may cause interference in other equipment. These emission limits represent electromagnetic compatibility requirements and have been selected to ensure that the disturbances generated by measuring relays and protection equipment, operated normally in substations and power plants, do not exceed a specified level which could prevent other equipment from operating as intended. Test requirements are specified for the enclosure and auxiliary power supply ports. 1.3 Immunity This standard is to specify the immunity test requirements for measuring relays and protection equipment in relation to continuous and transient, conducted and radiated disturbances, including electrostatic discharges. These test requirements represent the electromagnetic compatibility immunity requirements and have been selected so as to ensure an adequate level of immunity for measuring relays and protection equipment, operated normally in substations and power plants. NOTE 1 Safety considerations are not covered in this standard. NOTE 2 In special cases, situations will arise where the levels of disturbance could exceed the levels specified in this standard, for example where a hand-held transmitter or a mobile telephone is used in close proximity to measuring relays and protection equipment. In these instances, special precautions and procedures could have to be employed. SIST EN 60255-26:2014

Based on common installation practices, the recommended selection of test levels is the following: 4.2 Zone A, severe electrical environment The installation is characterized by the following attributes: • no suppression of electrical fast transients/bursts in the power supply and control and power circuits which are switched by relays and contactors; • no separation of the industrial circuits from other circuits associated with environments of higher severity levels; • no separation between power supply, control, signal and communication cables; • use of common multi-core cables for control and signal lines. The outdoor area of industrial process equipment, where no specific installation practice has been adopted, of power stations, open-air HV substation switchyards and gas insulated switchgear may be representative of this environment. 4.3 Zone B, typical electrical environment
The installation is characterized by the following attributes: • no suppression of electrical fast transients/bursts in the power supply and control circuits which are switched by relays (no contactors); • poor separation of the industrial circuits from other circuits associated with environments of higher severity levels; SIST EN 60255-26:2014
60255-26 © IEC:2013 – 11 –
• dedicated cables for power supply, control, signal and communication lines; • poor separation between power supply, control, signal and communication cables; • availability of earthing system represented by conductive pipes, ground conductors in the cable trays (connected to the protective earth system) and by a ground mesh. The area of industrial process equipment, the power plants and the relay room of open-air HV substations may be representative of this environment. 5 Emission 5.1 Emission enclosure Table 1 – Emission tests – Enclosure port Item Environmental phenomena Frequency range Limits Basic standard Test procedure 1.1 Radiated emission (below 1 GHz)ab

Measuring relays and protection equipment are apparatus which satisfy the class A limits. Limits can be measured at a nominal distance of 3 m, 10 m or 30 m. A measuring distance less than 10 m is allowed only for equipment which complies with the definition given in 3.2. In case of measurements at a separation distance of 30 m an inverse proportionality factor of 20 dB per decade shall be used to normalize the measured data to the specified distance for determining compliance. b
The limits specified for the 3 m separation distance apply only to small equipment meeting the size criterion defined in 3.2.
Conditional testing procedure • The highest internal source of an EUT is defined as the highest frequency generated or used within the EUT or on which the EUT operates or tunes. • If the highest frequency of the internal sources of the EUT is less than 108 MHz, the measurement shall only be made up to 1 GHz. • If the highest frequency of the internal sources of the EUT is between 108 MHz and 500 MHz, the measurement shall only be made up to 2 GHz. • If the highest frequency of the internal sources of the EUT is between 500 MHz and 1 GHz, the measurement shall only be made up to 5 GHz. • If the highest frequency of the internal sources of the EUT is above 1 GHz, the measurement shall be made up to 5 times the highest frequency or 6 GHz, whichever is less. 5.2 Emission auxiliary power supply port See Table 2.
