performance parameter
startUnder the conditions of rated voltage, rated power and cos φ = 1, when the load current of the watt-hour meter is the value specified in the table below, the watt-hour meter should have a pulse output and continuously record the point energy
insulation performanceAll the lines of the watt-hour meter can withstand a pulse voltage with a waveform of 1.2/50 uS and a peak value of 6KV between the metal parts accessible to the outside of the case. Under different models, each continuous experiment is 10 times, and there is no arc discharge or breakdown phenomenon. All the lines of the watt-hour meter can withstand the AC voltage of the actual sine wave with a frequency of 50HZ between the case or the outside of the case 2KV, and the experiment lasts for one minute without breakdown
diveWith anti-submersion design; when the current line of the watt-hour meter is at noon and the voltage applied to the voltage line is 115% of the rated, the test output of the watt-hour meter within the specified time should not generate more than one pulse
power consumptionPower consumption (voltage line: < 2W and 10VA); with automatic identification function of electric current direction.
(Voltage line)The reverse electrical energy has been metered in the total amount of electricity.
Limit operating voltageOperating voltage limit: 70~ 130% Ub
Maximum short circuit currentMaximum short-term current: 30 times the maximum current for 10ms (50HZ)
working environmentUse at ambient temperature -20 ° C to 55 ° C, relative humidity not exceeding 85% (without condensation)
