Terminals of one current circuit are considered to be at the same potential. If the test output is an optical test output, then it shall fulfil the requirements according 5.

INTERNATIONAL STANDARD IEC 62052-11

Expression of the performance of electrical and electronic measuring equipment has been taken from IEC For current circuits, the voltage is considered to be the same as for the related voltage circuit. Electrical connections shall be so designed that contact pressure is not transmitted through insulating material. Surge immunity test IEC This standard is intended to be used in conjunction with the appropriate part iecc IEC for the oec of equipment under consideration.

Tests — Test Sa: Each type has one designation only. Any ingress of water shall be only in a quantity not impairing the operation of the meter.

Outdoor meters shall withstand solar radiation. Screw connections transmitting contact force and screw fixings which may be loosened and tightened several times during the life of the meter shall screw into a metal nut. Unless otherwise specified, the normal conditions for insulation tests are: During this test no flashover, disruptive discharge or puncture shall occur. When several voltage circuits of a meter have a common point, this point shall be connected to earth and the impulse voltage successively applied between each of the free ends of the connections or the current circuit connected to it and earth.

NOTE Considering the electromagnetic environment of electricity metering equipment, the following phenomena are relevant: In the case of multiple values presented by a single display it shall be possible to display the content of all relevant memories.

Power consumption and voltage requirements IEC Information relating to this publication, including its validity, is available in the IEC Catalogue of publications see below in addition to new editions, amendments and corrigenda.

The minimum time between the impulses shall be 3 s.

Q2 Please tell us in what capacity ies you bought the standard tick all that apply. NOTE The accuracy may be determined by the registration method or other suitable means. A single electronic display may be used with multiple electronic memories to form multiple electronic registers.

When displaying the memory, the identification of each tariff applied shall be possible and, for automatic sequencing displays, each display of register for billing purposes shall be retained for a minimum of 5 s. Immunity to conducted disturbances, induced by radio-frequency fields IEC The holes in the insulating material which form an extension of the terminal holes shall be of sufficient size to also accommodate the insulation of the conductors.

These tests shall be made in normal conditions of use. It does not apply to: During type tests, the dielectric strength tests are considered to be valid only for the terminal arrangement of the meter which has undergone the tests. The test shall be carried out according to IECunder the following conditions: The pulse transition time rise time or fall time is the time of transition from one state to the other state, including transient effects.

Testing and measurement techniques — Section 6: The other terminal of this current circuit shall be open. It shall be impossible to reset the indication of the cumulative total of electrical energy during use.

The test shall be carried out according to IECwith the following temperatures: NOTE 3 The ratio of the highest to the lowest basic speed of the rotors of each of the meters of the same type shall not exceed 1,5. General terms relating to electrical measurements — Part These windows shall be of transparent material which cannot be removed undamaged without breaking the seal s. The marking shall be indelible, distinct and legible from outside the meter. Is my electricity meter single phase or three phase?

The test levels are regarded as minimum values to guarantee the proper functioning of the meter under normal working conditions. The terminal cover shall enclose the actual terminals, the conductor fixing screws and, unless otherwise specified, a suitable length of the external conductors and their insulation. To comply therewith they shall fulfil the following test.
