PREFACE

IN This edition of the “Instructions for the use and testing of protective equipment used in electrical installations” (hereinafter referred to as the Instructions) has been amended and supplemented to take into account the process of introducing modern protective equipment, the changing requirements of standards for specific types of protective equipment, as well as the results of an analysis of experience in their operation and testing .

The sections devoted to specific means of protection have been reworked, taking into account the updated range of products. In particular, significant changes have been made to the sections devoted to indicators and voltage alarms, and the standards for electrical testing of the working parts of indicators have been adjusted.

The section “Portable grounding” has been significantly revised. The requirements for portable grounding wires and the methodology for selecting their sections in operation have been clarified and brought closer to the requirements of European countries and brought into compliance with current Russian standards. A number of requirements for portable grounding rods have been clarified in connection with the trend of using methods for installing grounding connections in electrical distribution networks without lifting personnel onto the supports of overhead power lines.

IN the list of protective equipment includes kits for protection against electric arcs, the range of protective equipment for the face, eyes, and respiratory organs has been expanded, stationary voltage alarms, ladders and insulating fiberglass stepladders have been introduced. At the same time, a number of products that are not widely used are excluded from the list (cable damage indicator, voltage difference determination device

in transit).

The order of construction and presentation of the Instructions, if possible, has been preserved according to the 9th edition. “Rules for the application and testing of protective equipment used in electrical installations, technical requirements for them,” with the exception that all standards and terms of operational electrical tests are excluded from the main text and are given only in the appendices.

The list of annexes has been generally shortened, but has been supplemented with a list of regulatory documents and government documents used in the preparation of the Instructions

standards.

With the release of this edition of the Instructions, the 9th edition of the “Rules for the use and testing of protective equipment used in electrical installations, technical requirements for them” (Moscow: Glavgosenergonadzor, 1993) becomes invalid.

1.5. GENERAL RULES FOR TESTING PROTECTIVE MEANS

1.5.1. Acceptance, periodic and type tests are carried out at the manufacturer according to the standards given in Appendices 4 and 5, and the methods set out in the relevant standards or technical specifications.

1.5.2. In operation, protective equipment is subjected to regular and extraordinary operational tests (after a fall, repair, replacement any parts if there are signs of malfunction). The standards for operational tests and the timing of their implementation are given in Appendices 6 and 7.

Mechanical tests are carried out before electrical tests.

1.5.4. All testing of protective equipment must be carried out by specially trained and certified personnel.

1.5.5. Before testing, each protective equipment must be carefully inspected to check the presence of manufacturer's markings, numbers, completeness, absence of mechanical damage, and the condition of insulating surfaces (for insulating protective equipment). If the protective equipment does not comply with the requirements of this Instruction, tests are not carried out until the identified deficiencies are eliminated.

1.5.6. Electrical tests should be carried out with alternating current of industrial frequency, as a rule, at a temperature of plus (25±15) °C.

Electrical tests of insulating rods, voltage indicators, voltage indicators for checking phase coincidence, insulating and electrical clamps should begin with checking the dielectric strength of the insulation.

The rate at which the voltage rises to 1/3 of the test voltage can be arbitrary (a voltage equal to the specified voltage can be applied by a push); a further increase in voltage should be smooth and fast, but allowing the readings of the measuring device to be read at a voltage of more than 3/4 of the test voltage. After reaching the rated value and holding at this value for a rated time, the voltage must be smoothly and quickly reduced to zero or to a value not exceeding 1/3 of the test voltage, after which the voltage is turned off.

1.5.7. The test voltage is applied to the insulating part of the protective equipment. In the absence of an appropriate voltage source for testing entire insulating rods, insulating parts of voltage indicators and voltage indicators for checking phase coincidence, etc. It is allowed to test them in parts. In this case, the insulating part is divided into sections to which a part of the normalized full test voltage is applied, proportional to the length of the section and increased by 20%.

1.5.8. Basic insulating electrical protective equipment intended for electrical installations with voltages above 1 to 35 kV inclusive are tested with a voltage equal to 3 times linear, but not lower than 40 kV, and those intended for electrical installations with a voltage of 110 kV and above - equal to 3 times phase.

Additional insulating electrical protective equipment is tested by voltage according to the standards specified in Appendices 5 and 7.

1.5.9. The duration of application of the full test voltage is usually 1 min. for insulating protective equipment up to 1000 V and for insulation made of elastic materials and porcelain and 5 min. - for insulation from layered dielectrics.

For specific protective equipment and working parts, the duration of application of the test voltage is given in Appendices 5 and 7.

1.5.10. Currents flowing through the insulation of products are standardized for electrical protective equipment made of rubber and elastic polymer materials and insulating devices for live work. Operating currents flowing through voltage indicators up to 1000 V are also standardized.

Current values are given in Appendices 5 and 7.

1.5.11. Breakdown, flashover, and surface discharges are determined by turning off the testing facility during testing, by readings from measuring instruments, and visually.

1.5.12. Electrical protective equipment made of solid materials should be checked by touch immediately after testing for the absence of local heating due to dielectric losses.

1.5.13. If a breakdown, flashover or surface discharge occurs, the current through the product increases above the rated value, or local heating occurs, the protective equipment is rejected.
