Power sensor technology trends

In modern times, power systems are increasingly complex and power sensor technology is constantly evolving. They help achieve precise control and optimal utilization of electrical energy by measuring current and voltage. Power sensors can be divided into two types: non-contact and contact, each with its own advantages and applicable scenarios.

Non-contact power sensors, such as magnetic sensors or Hall effect sensors, measure the current value by inducing changes in the magnetic field produced by the current and determine the power factor based on the phase difference between the current and the voltage. This technology is suitable for situations where direct contact with circuits needs to be avoided, and is characterized by high accuracy and fast response.

On the other hand, contact power sensors, like resistive sensors, measure the current value by inserting a precise resistor and calculate the power factor based on the phase difference. This sensor directly measures current without the need to induce a magnetic field and is suitable for different types of circuits.

A wide range of applications for power sensors include industrial automation, energy management systems and power systems. They feature high accuracy, wide frequency range, stability and reliability, and are suitable for a variety of circuits and environmental conditions. Users can easily install and use these sensors to obtain real-time power consumption information for effective energy management and power system optimization.

Overall, power sensors are an indispensable key component in modern power systems, and their evolving technology trends will continue to promote more efficient and sustainable use of electrical energy.
