I. Industry Pain Points & Product Solutions

01. Typical Power Quality Issues in Power Distribution Across Industries

	PV / Wind Power:	Grid-tied inverters introduce harmonics and power fluctuations, which may cause voltage swings, flicker and frequency deviation.
	Metallurgy / Petrochemical:	High-power impact loads and variable-frequency drives often trigger three-phase unbalance and voltage sags, disrupting continuous production.
	Semiconductor / Precision Manufacturing:	High-precision equipment is sensitive to power quality. Voltage disturbances and harmonics threaten process stability and equipment reliability.
	Data Center:	Non-linear loads such as UPS and switching power supplies continuously generate harmonics and voltage fluctuations, straining the distribution system.

02. PQSENSOR100 Power Quality Monitoring Solution

Built for industrial distribution, substations and critical loads. It supports local & remote monitoring, capturing voltage, current, harmonics, interharmonics, flicker, frequency deviation, 3-phase unbalance and waveforms. Local touchscreen + cloud visualization enable anomaly detection, disturbance tracing and data-driven O&M & fault analysis.

II. Four Core Features

1. 0.5~60th Harmonic & Interharmonic Recording

Full-spectrum harmonic monitoring. Captures RMS, THD, phase angle and PF. Cloud export of harmonic trends for interference source localization.

2. Full Transient Event Logging

Records voltage swell/sag/short interruption and RVC events with timestamp, duration & magnitude for local/cloud joint analysis.

3. Fault Oscillography & Long-Term Waveform Storage

Multi-channel real-time linked oscillography before/during/after faults for traceability and root-cause analysis.

4. Two Mounting Options

Embedded in-cabinet or wall-mounted outside cabinet, flexible for site layout and easy O&M.
