Power Quality Analysers

Description

Power Quality Analysers are advanced measuring instruments used to monitor, record, and analyze electrical parameters in power systems. They detect disturbances such as harmonics, voltage sags, swells, flicker, transients, and unbalances that can affect the efficiency and reliability of electrical equipment. Widely used in industries, utilities, and commercial facilities, these devices help maintain compliance with power standards, improve system efficiency, and prevent costly downtime.
