Power Meters / Analysers

A Power Meter / Analyser is a high-precision instrument designed to measure electrical energy flow with extreme accuracy. These devices go beyond basic metering by providing detailed insights into power consumption, efficiency, and harmonic distortion across multiple phases. Unlike standard multimeters, power analysers are built to handle complex waveforms and high-frequency noise, making them indispensable for engineers developing power electronics. They are essential in sectors such as electric vehicle (EV) powertrain testing, renewable energy integration, and the optimisation of high-efficiency industrial motors.

Why Choose a Power Meter / Analyser?

Multi-Phase Measurement: Simultaneously monitor voltage, current, and power across multiple inputs for comprehensive system analysis.
High Bandwidth & Accuracy: Capture high-frequency harmonics and switching losses with laboratory-grade precision and stability.
Efficiency Calculation: Automatically determine input-to-output efficiency for inverters, converters, and motor drives.
Real-Time Waveform Analysis: Visualise complex electrical signals and transient events to identify power quality issues instantly.

Core Applications

EV & Automotive Testing: Analysing the efficiency of traction motors, battery management systems, and on-board chargers.
Renewable Energy Systems: Benchmarking the performance of solar inverters and wind turbine power conversion units.
Power Quality Auditing: Detecting total harmonic distortion (THD) and flicker in industrial grids to ensure regulatory compliance.
Consumer Electronics: Measuring standby power and operational energy use to meet strict international “green” standards.
