Tests for variation caused by Influence quantities should be performed independently with all other influence quantities at their reference conditions (see Table 11).
8.2.1 Tests of the influence of d.c. component in the current circuit
The tests of the influence of d.c. component in the current circuit shall be made with the circuit shown in Figure A.1 or with other equipment able to generate the required wave-forms, and the current wave-forms as shown in Figure A.2.
The variation in percentage error when the meter is subjected to the test wave-form given in Figure A.2 and when it is subjected to the reference wave-form shall not exceed the limits of variation given in Table 8.
NOTE The values given in the Figures are for 50 Hz only. For other frequencies the values have to be adapted accordingly.
8.2.2 ContInuous magnetic induction of external origin
The continuous magnetic induction may be obtained by using the electromagnet according to Annex B, energized with a d.c. current. This magnetic field shall be applied to all accessible surfaces of the meter when it is mounted as for normal use. The value of the magneto-motive force applied shall be 1 000 At (ampere-turns).
8.3 Test of starting and no-load condition
For these tests, the conditions and the values of the influence quantities shall be as stated
in 8.5 except for any changes specified below.
8.3.1 InItial start-up of the meter
The meter shall be functional within 5 s after the reference voltage is applied to the meter terminals.
8.3.2 Test of no-load condition
When the voltage is applied with no current flowing in the current circuit, the test output of the meter shall not produce more than one pulse.
For this test, the current circuit shall be open-circuit and a voltage of 115 % of the reference voltage shall be applied to the voltage circuits.AS 62053.23 pdf download.
