Specific terms according to the type of instrument IEC After the test, iecc meter shall show no damage and shall comply with the dielectric strength tests of 7. The active tariff rate shall be indicated. Tests — Tests B: After these tests, the meter shall show no damage and operate as specified in the relevant standards.
See also Annex B, Figure B.

During the test of a current circuit, the terminals ief the other circuits shall be connected to earth and the impulse voltage shall be applied between one of the terminals of the current circuit and earth. On-line information is also available on recently issued publications, withdrawn and replaced publications, as well as corrigenda.
Q2 Please tell us in what oec ies you bought the standard tick all that apply. Any ingress of water shall be only in a quantity not impairing the operation of the meter.
INTERNATIONAL STANDARD IEC 62052-11
The clearance and creepage distances between terminals of circuits with reference voltages over 40 V shall not be less than stated in Table 3a.
To make sure that we continue to meet your needs, your feedback is essential. Collection of meter dependability data from the field This part is a standard for type testing electricity meters. These windows shall be of transparent material which cannot be removed undamaged without breaking the seal s.
In this way, the two voltage terminals of the meter under test which are not affected by the earth fault are connected to 1,9 times the nominal phase voltages. The damp heat test also serves as a corrosion test. During the test of a voltage circuit, the terminals of the other circuits and one of the terminals of the voltage circuit under test shall be connected to earth and the impulse voltage shall be applied between the other terminal of the voltage circuit and earth.
Tests — Test Db and guidance: It also applies to operation indicator s and test output s. All parts which are subject to corrosion under normal working conditions shall be protected effectively. IP51, but without suction in the meter.
For rack-mounted meters, the mechanical properties are not covered in this standard.
Stationary use at weatherprotected locations Amendment 1: If this is not possible reference shall be made to a connection diagram. Surge immunity test 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 insulating properties of laquer, enamel, ordinary paper, cotton, oxide film on metal parts, adhesive film and sealing compound, or similar unsure materials, shall not be regarded as sufficient for supplementary insulation.
The manner of fixing the conductors to the terminals shall ensure adequate and durable contact such that there is no risk of loosening or undue heating. It comprises one or more magnets and their adjusting devices. NOTE 2 Values higher than 1 h should be the subject of purchase contract.
During the test, a temporary degradation or loss of function or performance is acceptable. It generally comprises electromagnets with their control devices.

The result is judged visually. Reference number IEC For examples of the test set-up, see Annex E, Figures E. Tests — Test Ka: A single electronic display may be used ief multiple electronic memories to form multiple electronic registers.
Tests — Test Fc: NOTE 2 Operation and storage and transport of the meter at the extremes of this temperature range class 3K7 should only be for a maximum period uec 6 h. Information under points d to k shall be marked on a name-plate preferably placed within the meter.
For testing purposes, the register of the electricity meter shall have a resolution of at least 0,01 units.
NOTE 1 Longer retention time of the non-volatile memory should be the subject of a purchase contract.
For current circuits, ice voltage is considered to be the same as for the related voltage circuit. A recommended test sequence is given in Annex F.
The drums which indicate a decimal fraction of the unit shall be marked differently when they are visible.
