Introduction to Energy Meters

An electricity meter or energy meter is a device that measures the amount of electric energy consumed.

There are two types of Domestic Ordinary Power Consumers meters:

• Single Phase
• Three Phase

Most of TNB's energy meters are electronic meters. Electronic meters are identifiable through the LCD display panels. Whilst electromechanical meters are still in use, TNB is gradually phasing them out through replacement programs.  All TNB energy meters installed at the premises have been calibrated and tested in accordance to Malaysian Standards ISO/IEC 17025: 2005.

How to Read Your Energy Meter

For billing purposes, TNB will require your energy consumption reading measured in kilowatt hour (kWh). This reading is available on the LCD display of the meter, as shown in the following illustrations. The numbers on the LCD display denotes the accumulated energy used and is measured in kWh. This is the information you will need to submit to TNB.

For Single Phase Meters

Shown below are the 4 most common single phase electronic energy meters used in TNB. The kWh consumption is shown on the LCD display. There is no need to push any button.

For Three Phase Meters

Highlighted below are the 5 main types of three phase energy meters used in TNB. To read the kWh consumption on these meters, you need to wait for the screen to display the kWh consumption. By default the screen will scroll the kWh reading, the kVARh reading and a blank screen at 10 seconds intervals.

You do not need to push any buttons. Wait until the screen displays the reading as shown in the images below and jot down the reading. You are required to submit only the kWh reading to TNB.
