A Power Quality Clamp Meter is an advanced electrical measuring device that is used to check both current flow and overall power quality in electrical systems. It works by clamping around a live conductor without disconnecting the circuit, making it safe and convenient to use. In Bangladesh, it is widely used in industries, electrical maintenance, and power systems to analyze voltage, current, power factor, frequency, and harmonic distortion. This device helps engineers quickly identify electrical problems such as voltage drops, surges, unstable supply, and waveform distortion. By providing accurate real-time data, it supports efficient troubleshooting and better power system management. Overall, it is an essential tool for maintaining stable and reliable electrical performance in industrial and commercial environments.
