Press Release: Acrel APView Series All-in-One Power Quality Monitor Safeguards Grid & Industrial Operation with Full-Dimension Monitoring and Fault Recording

2026-08-07

Growing Industry Pain Points Drive Demand for Class A High-Accuracy Monitoring

The rapid expansion of rectifiers, inverters, variable frequency drives and renewable distributed generation has sharply elevated nonlinear load ratios on power grids. Minor power quality anomalies can trigger misoperation of precision semiconductor equipment, unplanned production line shutdowns and massive economic losses, while severe transient faults risk large-scale grid instability.

Conventional monitoring tools often suffer from incomplete parameter coverage, insufficient transient capture speed and lack of standardized fault data output, failing to meet strict requirements for compliance inspection, fault arbitration and long-term operational statistics. The APView series stands out with authoritative third-party certifications: all models pass Class A certification from Jiangsu Electric Power Research Institute and KEMA EMC testing, delivering Class-A measurement accuracy to satisfy high-standard industrial and utility monitoring scenarios.

Core Capabilities: Full Steady-State, Transient & Transient Disturbance Coverage

Built around the design philosophy of “full parameters, high precision, easy operation”, APView covers steady, transient and ultra-fast transient power events to supply complete data evidence for power quality optimization and fault tracing:

Comprehensive Steady-State Monitoring
Real-time measurement of RMS voltage/current, frequency deviation, 2nd–63rd harmonics, 0.5–62.5th interharmonics, three-phase unbalance and voltage flicker, with synchronous waveform and spectrum visualization for intuitive condition tracking.
Intelligent Transient Disturbance Capture & Sag Source Localization
Ultra-fast detection of voltage swells, sags and short interruptions. Its proprietary equivalent impedance algorithm accurately judges whether faults originate from busbar or feeder sides, and supports compliance analysis against SEMI F47 and ITIC equipment tolerance curves, shifting operation mode from passive breakdown repair to proactive risk prevention.
Transient Capture & Standard Fault Wave Recording
Captures abrupt voltage and current transients with multi-trigger fault recording functions. It exports data in universal COMTRADE format, providing complete traceable evidence for post-fault root cause analysis.
Standardized Intelligent Data Analytics & Ultra-Long Data Storage
Fully aligned with State Grid standard Q/GDW 10650.8, the device automatically generates daily statistical reports including maximum, minimum, average and 95% probability values for steady-state, harmonic, interharmonic and transient events. All daily statistical data can be stored locally for up to 5 years to support long-term power quality trend analysis and compliance auditing.
Simplified Remote Operation & Multi-Platform Interconnection
Embedded built-in Web Server enables remote real-time data viewing and parameter configuration via standard browsers without extra software. Compatible with Modbus-RTU/TCP and IEC 61850 communication protocols, APView seamlessly connects to energy efficiency management platforms to realize unified on-site monitoring and cloud centralized control.

Field Case: Stable Operation Guarantee for Shanghai Semiconductor Fabs

Semiconductor manufacturing equipment is extremely sensitive to voltage fluctuations and harmonic interference. A Shanghai-based semiconductor technology enterprise installed the APView500 unit at its 10kV substation incoming cabinet. The device continuously tracks voltage swell/sag incidents and harmonic/interharmonic levels, instantly recording all transient disturbances. The complete high-precision dataset eliminates blind spots in power quality analysis and effectively avoids costly production line scrap and shutdown risks induced by grid abnormalities.

Diversified Model Matrix for Full-Scenario Adaptation

Acrel designs differentiated APView models to match all voltage levels and application segments:

APView500: Deployed on 110kV, 35kV and 10kV main incoming feeders, critical outgoing lines, and medium-voltage grid connection points for photovoltaic and energy storage stations;
APView400 / APView350: Optimized for 0.4kV distribution rooms, low-voltage grid-connected cabinets and small-scale PV & energy storage low-voltage access points.
