Compressed air

Leak rate calculator

Use this calculator to automatically determine leak rates from compressor power data. Upload a CSV file with power measurements and configure the analysis parameters. The DateTime should be in the second column and the current should be in the third column.

Step 1: Upload CSV File

Step 2: Enter System Voltage & Power Factor

Enter the 3-phase system voltage and motor power factor. Real power is calculated as: P = √3 × V × I × PF

System Voltage (V):

Common values: 208V, 460V, 600V

Power Factor:

Loaded compressor motors: 0.85–0.95

Step 3: Select Control Type and Configure

VFD Compressor Non-VFD Compressor

VFD Configuration: Power-Flow Data Points

Enter at least 4 power-flow data points. Click "Add Point" for more rows.
