How does the Single-Phase APS energy meter works?

➡Answer: Single-Phase APS energy meter is an intelligent measurement device, with advanced electrical technologies and communication modes realizing the automatically collection and transportation of electrical data. Below is the brief of Single-Phase APS energy meter’s working principle.

 

  1. Measurement function: 

Single-Phase APS energy meter equips advanced measuring chip, which measures single-phase AC current real-time. The measuring chip is able to measure voltage, effective value of current precisely, and according to the formula of electricity efficiency ( P=UIcosθ, U equals voltage, I equals current and cosθ is efficiency factor) for constant efficiency, then accumulating the total electricity quantity of a period of time.

 

  1. Data storage and processing:

The internal of energy meter equips with non-volatile memory for recording electricity usage data, running status, necessary event records and etc. These data will be update&restore when comes to certain time interval or specific events.

 

  1. Remote communication:

APS energy meters equip with wireless communication modes inside, such as 4G, PLC(Power Line Communication) or LoRa, which could send relative electricity data and certain messages to power utilities’ data center or other monitoring platform regularly or according to demands.

 

  1. Tariffs management:

As APS energy meter supporting tariff managements, it can also receive orders from power utilities, such as prepayment recharge, remote switch ON/OFF and etc. When customers’ account balance running out, energy meter could cut off power automatically and restart the power when after recharging. It supports multi-tariffs management, realizing 4 tariffs 8 time-periods billing.

 

  1. Secure encryption:

We apply secure encryption technology to the process of data transmission, ensuring safety of message during wireless transmission and avoiding data tampering&theft.

 

  1. Smart features：

Single-phase APS meter also equips data analysis, energy consumption statistics, fault alarm and etc, helping clients and power utilities better management in power usage and improving energy efficiency.  

 

 

According to all upon, automatically collecting&transmitting&operating of electricity consumption data, improving the level of informatization management in power supply and consumption stage.
