Harmonic Analysis and Power Quality

Harmonic analysis up to the 50th order provides detailed insight into power quality, THD (Total Harmonic Distortion), and individual harmonic magnitudes, essential data for compliance with IEC 61000-3-2 harmonic emission standards and for optimizing power converter switching strategies. The 500 kSPS sampling rate captures fast transients and accurately measures power in high-frequency switching converters where lower sampling rates introduce aliasing errors.

Direct High-Voltage, High-Current Input

Simultaneous measurement of voltage, current, power, power factor, and harmonics delivers a complete power characterization in real time. The direct 800 V and 30 A input ranges cover most power electronics testing scenarios without external transducers, simplifying test setups and reducing measurement chain uncertainty.

Applications

Power supply manufacturers, EV charger designers, motor drive producers, and LED driver engineers all use the 7130 for efficiency optimization and regulatory compliance. Indian manufacturers designing and producing power electronics for domestic and export markets rely on the 7130 for the measurement precision that competitive efficiency ratings demand.

GSAS Micro Systems provides the Microtest 7130 to power electronics manufacturers, energy efficiency testing laboratories, and R&D centers across India with INR invoicing and application support. Teams in Bengaluru, Hyderabad, Chennai, Pune, Mumbai, and Delhi NCR provide demonstration, calibration, and integration services.
