A single phase power meter is a type of meter that measures power consumption from a single-phase electric power supply. These meters are used in a variety of different applications, including power distribution, power metering and energy auditing.

In electrical circuits, phases are the voltage and current on a live wire and also a neutral wire. The live wire carries the load while the neutral line completes the circuit for the return of current to the source.

Most residential homes use a single-phase power supply to distribute electricity. This is because the majority of people who live in countries where electricity is readily available, want to use it to run their various home appliances and other devices.

This has led to the development of many types of single-phase meters that are designed to help people better monitor their power usage and also help them control their energy costs. These meters have features such as balance alarm, IC card payment, multiple encryptions of data and also pre-sale electricity which allows the meter to automatically shut down when it is not in use.

The RL78/I1B microcontroller realizes accurate metrology via a 24-bit Delta-Sigma A/D converter integrated with a phase adjustment circuit and high-pass filter function, and by a real-time clock with clock error correction function. It also offers an LCD controller/driver and a high-speed on-chip oscillator, which make it ideal for basic single-phase power meters.

It is also capable of RS485 communication interface based on Modbus-RTU protocol. It has multiple registers for users to choose which register corresponds to which measured electrical parameters. It can also be controlled through panel keys or communication.

There is an increasing demand for smart meters that can communicate with each other to enable efficient and safe power distribution. These are essential as government regulations and the cost of building power-generating systems are driving a move towards a more energy-efficient system.

A smart power meter has the ability to send readings over the Internet to an automated billing center using a wireless communications network. These devices can be controlled and maintained remotely.

They can also be used to monitor the energy usage of a number of different users, such as an individual or an organization. This can help to reduce the risk of power theft.

Depending on the arrangement between the customer and the electricity company, the meter may be read by an employee of the power company or by the customer himself or herself. In either case, the meter will need to be checked and maintained by a representative at least once a year.

It is important to ensure that the meter is not subject to creep, which can affect the accuracy of the meter. Creep can result in the meter readings being incorrect or incorrectly interpreted as watt-hours consumed, which could lead to false billing.

A smart power meter can also be used to detect tampering, which is a common method of stealing electricity. A power company can then use the meter readings to uncover tampering and then resolve the issue.
