Electric Energy Meter

Electric Energy Meter


An electric meter, or energy meter, is a device that measures the amount of electric energy consumed by a building, tenant space, or electrically powered equipment, also known as watt hour meter and kilowatt hour meter,


When using the electric energy meter, it should be noted that the electric energy meter can be directly connected to the circuit for measurement under the condition of low voltage (no more than 500 volts) and small current (tens of AMPS). Under the condition of high voltage or large current, the electric energy meter cannot be directly connected to the Circuit, and it needs to be used with a voltage transformer or current transformer.


HTW, has been focused on the testing and certification services in an early time, and we were certified as an IECEE CBTL. All these ensure our efficiency and accurate testing and certification capability.

Experience In Testing Process

1. the reason of radiation test failed

There are many reasons for EMC radiation tests failed according to the standard, such as interface filtering, cable design, grounding, shielding etc. 

Generally speaking, it is the problem of PCB design. 


For TCB, a multilayer board is a recommended choice, as it can reduce impedance.

The circuit on the PCB board is required to be straight and short.



2. the problems of product information

Label, Schematic, User manual, CDF/BOM, PCB layout
