Key Features and Functional Highlights

✅ IEC 61000-4-30 Class B Compliant

Certified for Class B accuracy, the AEMC 8333 provides high-confidence data that is ideal for general power quality studies, energy audits, and preventative maintenance. It’s perfect for facilities that don’t require regulatory-grade precision but still need detailed and reliable analysis.

✅ Real-Time 4-Channel Monitoring

Simultaneously monitors:

• Four voltage channels (L1, L2, L3, N)
• Three current channels
• Neutral current calculated and displayed This enables complete analysis of three-phase systems, including imbalances, neutral currents, and phase relationships, supporting both wye and delta configurations.

✅ Comprehensive Power and Energy Measurements

Capture a wide range of power quality metrics including:

• True RMS Voltage and Current
• Frequency
• Active, Reactive, and Apparent Power
• Energy Consumption (kWh, kVARh, kVAh)
• Power Factor and Displacement Power Factor (DPF)
• Unbalance and Flicker
• Demand (Sliding Window and Fixed Window)

✅ Advanced Harmonic Analysis

• Measures voltage and current harmonics up to the 50th order
• Calculates THD (Total Harmonic Distortion) and individual harmonic magnitudes
• Identifies harmonic-related power losses, transformer heating, and equipment malfunction issues

✅ Voltage Events Detection

Detect and record:

• Sags (dips)
• Swells
• Interruptions
• Ideal for identifying power disturbance sources that impact equipment operation

✅ Inrush Current Capture

Capture inrush currents with high accuracy to evaluate motor startup profiles, circuit breaker tripping, and transient loading effects.

User Interface and Data Handling

✅ Large Colour Graphical Display

Equipped with a bright, backlit ¼ VGA colour display, the AEMC 8333 provides real-time waveform viewing, phasor diagrams, and harmonic spectrums for quick, on-site diagnostics.

✅ Extensive Data Logging and Storage

• Built-in memory stores months of data
• Configurable logging intervals (from seconds to hours)
• Ideal for long-term monitoring and trend analysis

✅ Flexible Communication Options

• USB, Ethernet, and Wi-Fi connectivity for fast and convenient data transfer
• Compatible with AEMC’s DataView® software for in-depth data analysis, report generation, and real-time viewing
