In interior decoration, circuit design and decoration are very important. Hydropower is a concealed project, so it is necessary to pay attention to specific construction techniques during decoration to ensure the quality of construction. When decorating the circuit, pay attention to the design of the wire. Do you know what the power failure warning of a three phase meter is like?
Power failure warning: If the user does not insert the card to respond when the warning reminds, when the remaining power is the user's agreed on alarm power (or 10% of the current purchase power), the meter will switch off the power off the warning and display an "open switch" prompt At this time, insert the IC card into the card socket once and the power supply will be restored. If you cannot find the IC card of this watch after the switch is opened, you can borrow the neighbor's IC card to insert it to restore the power supply. When the remaining power in the meter is less than the "alarm power", the "alarm indicator" will always light up to remind.
Technology is constantly advancing. In addition to three-phase meters, new meters are constantly appearing, such as Electromechanical KWh Meter . These new meters will be easier to use than the old meters long ago and can be more convenient to see. The counting is also more accurate. yhddb.com
