virtajännitemittaus

Virtuaalijännitemittaus, often abbreviated as VJT, is a method used in electrical engineering and measurement to determine the voltage of a circuit or system without directly connecting a measuring device. This technique is particularly useful in high-voltage or hazardous environments where physical contact could be dangerous.

The principle behind virtual voltage measurement involves using sensors and signal conditioning equipment to capture electrical signals from the circuit. These signals are then processed and analyzed using software algorithms to calculate the voltage. The sensors can be placed at a safe distance from the high-voltage components, reducing the risk of electrical shock or damage.

One common application of virtual voltage measurement is in power transformers. By placing sensors on the transformer's secondary winding, the voltage can be measured without the need for direct contact with the primary winding. This approach is also used in other high-voltage equipment such as switchgear and circuit breakers.

The advantages of virtual voltage measurement include improved safety, reduced maintenance requirements, and the ability to monitor voltages in real-time. However, the accuracy of the measurements depends on the quality of the sensors and the effectiveness of the signal processing algorithms.

In summary, virtual voltage measurement is a non-invasive technique that enables safe and accurate voltage monitoring in various electrical systems. It leverages modern sensor technology and data processing capabilities to provide valuable insights without the need for direct physical contact.
