Background
User-side power distribution monitoring at 10/0.4kV requires continuous visibility of both electrical parameters (voltage, current, power) and equipment conditions
such as temperature, humidity, partial discharge, and arc flash. Without real-time monitoring, hidden faults can escalate into unplanned outages and equipment damage.
Pain & Value
Your Pain Points
Blind spots in insulation and manual inspection fail to warn of sudden switchgear faults, causing costly downtime.
Busbar overheating and insulation degradation are invisible to the naked eye, posing fatal threats to assets and personnel.
Scattered sub-stations lack centralized SCADA visibility, making fault troubleshooting slow, reactive, and labor-intensive.
Our Acrel Value
Eliminate blind spots with wireless passive temperature tags and UHF/Multi-sensor PD monitoring. Catch defects before failure.
Deploy ultra-fast arc flash relays to isolate faults within milliseconds, minimizing panel damage and ensuring NFPA/IEC safety compliance.
Streamline O&M via Modbus/MQTT. Turn reactive maintenance into predictive alerts, reducing operational costs by up to 30%.
Solution
Acrel-2000 Electrical Power Monitoring System
Acrel-2000 collects and displays voltage, current, power, harmonics, temperature, humidity, partial discharge, and arc flash events in a single interface.
Real-time alarms and historical records support condition-based awareness for distribution assets.
Partial Discharge Monitoring
APD300 detects insulation degradation through AE, TEV, and UHF methods. The system captures discharge patterns and provides early visibility into insulation condition before failure occurs.
Temp. & Humi. Monitoring
ATE400 monitors busbar joints, breaker contacts, and cable terminals using CT-powered passive technology. AHE100 monitors cabinet temperature and humidity. Data is collected via ATC600 gateway.
