The main advantages of Electro Mechanical Meter:
1. Electro Mechanical Meter with high accuracy, accurate measurement
As the Electro Mechanical Meter measurement principle is the data sampling, by the multiplier to complete the measurement of electrical power, the measurement accuracy is high. 2.0-class Electro Mechanical Meter basic error between 0.2 to 0.6, equivalent to 10% of the mechanical watch error. All electronic energy meter high sensitivity, the same specifications of the mechanical watch, such as 5 (20) A, starting current of 25 mA, while the electronic watch is only 10 mA, in a small load can be accurately measured.
2. Verification of reduced workload, improve work efficiency
3. Since the Electro Mechanical Meter without mechanical devices, without repair, eliminating the repair process.
4. Electronic meter error curve is good, in the load point for a flat line, adjust the error for the software adjustment, the whole line translation, easy to adjust, without opening the table cover, saving time.
5. Electronic watch with a pulse signal input to the verification device for verification, as long as the connection pulse line, a sampling that is successful, saving time.
6. Electronic watch light weight, small size, easy to transport
All-electronic single-phase energy meter small size, light weight. Transport, can withstand a slight shock, the error is not easy to change.
7. All-electronic energy meter power consumption is small, is conducive to reducing line loss
Electronic power meter for all electronic components, the components of the working voltage, operating current are millivolt and milliampere level, the electronic components of their own power consumption is small, after testing, the same specifications of the electronic table power consumption is less than 0.6 W, While the power consumption of mechanical energy meter nearly 1.8W. According to my office is running mechanical single-phase energy meter 180,000 calculation, if all replaced by all-electronic single-phase energy meter, the daily power consumption reduced by 5 184 kW · h, to reduce the line loss has a significant effect.
8. With anti-tampering function
All-electronic energy meter voltage circuit and the current loop is not an independent circuit, the end of the table terminal is not induction voltage meter voltage hook, is conducive to anti-tampering. The current circuit of the electronic energy meter is made of manganese and copper, and the resistance value is low. Electronic meter counters with anti-down metering function, regardless of the current loop is forward or reverse access, can be positive measurement.
9. All electronic energy meter failure rate is low
All-electronic energy meter current loop overload capacity, not easy to burn table. At the same time using a dedicated large-scale integrated circuit, no mechanical work in the static wear. I use the all-electronic energy meter in the past two years, the failure rate from 15% in 1999 fell to 1.1% now.
10. Conducive to the reform of meter reading
The working principle of the all-electronic watt-hour meter determines that the pulse signal is the most basic data information without any conversion. With all-electronic energy meter can be achieved remote meter reading, construction is simple, accurate and convenient copy.
