Power detection equipment is a critical tool used for testing, analyzing, and monitoring the performance of power systems. Its functions cover various fields such as power security, efficiency optimization, and fault troubleshooting. Below is a detailed explanation of its core functions and application scenarios:
Ensuring Safe Operation of Power Systems
- Over-voltage/Under-voltage Protection: Monitor voltage fluctuations in real time to prevent equipment damage due to excessively high voltage (such as lightning strikes) or too low voltage (such as grid failures).
- Leakage and Short-circuit Detection: Identify hidden dangers such as insulation breakdown and grounding faults to avoid the risk of electric shock or fire.
- Harmonic Analysis: Detect harmonic pollution in the power grid (such as high-order harmonics generated by nonlinear loads) to reduce interference with precision equipment.
Application Scenarios:
- Household Electricity Use: Leakage protectors (RCDs) automatically cut off abnormal circuits.
- Industrial Sites: Install power quality analyzers to prevent production line downtime.
Evaluating Power Performance and Energy Efficiency
- Power Parameter Measurement: Accurately measure voltage, current, power factor, active/reactive power, etc., to optimize energy usage efficiency.
- Energy Efficiency Certification: Verify that equipment complies with international standards (such as 80 PLUS power supply certification) to reduce standby power consumption.
- Load Capacity Testing: Simulate different load conditions (such as peak and continuous loads) to check the stability of the power supply.
Application Scenarios:
- Data Centers: Test the switching time and load-carrying capacity of UPS (Uninterruptible Power Supplies) to ensure uninterrupted server power.
- New Energy Field: Evaluate the conversion efficiency of photovoltaic inverters (such as MPPT tracking performance).
Fault Diagnosis and Preventive Maintenance
- Waveform Analysis: Capture voltage/current waveforms with an oscilloscope to identify distortions (such as voltage sags and frequency deviations).
- Battery Health Monitoring: Measure parameters such as internal resistance and capacity to predict the aging risk of batteries (such as backup power for telecommunication base stations).
- Thermal Imaging Detection: Use infrared thermography cameras to locate local hot spots on power equipment to avoid malfunctions caused by poor connections.
Application Scenarios:
- Electric Vehicle Charging Stations: Regularly test the output characteristics of charging modules to prevent interruptions during charging.
- Medical Equipment: Ensure the power purity supplied to sensitive equipment such as MRI and CT machines.
