Võimsusmõõtur

Võimsusmõõtur, also known as a power meter, is a device used to measure the amount of electrical power consumed by an electrical device. This measurement can be instantaneous, showing the current power draw, or it can accumulate power over a period of time, often displayed in kilowatt-hours (kWh). Power meters are essential for understanding and managing energy usage, both in households and industrial settings.

There are several types of power meters, ranging from simple plug-in devices that monitor a single appliance to more complex industrial meters that are integrated into electrical panels. Some power meters also provide additional information, such as voltage, current, power factor, and frequency. This data can be valuable for identifying energy-inefficient devices, detecting potential electrical problems, and optimizing energy consumption.

In residential settings, power meters can help homeowners track their electricity bills and identify which appliances are the biggest energy consumers. This awareness can lead to behavioral changes, such as unplugging devices when not in use or upgrading to more energy-efficient models. For businesses and industries, power meters are crucial for monitoring large-scale energy consumption, identifying areas for cost savings, and ensuring compliance with energy regulations. Advanced power meters can also provide real-time data and remote monitoring capabilities, allowing for more proactive energy management.
