NETA & NFPA 70B Electrical Fault Severity Grading with Load Correction
Automate electrical fault severity grading based on temperature rise (ΔT) and apply electrical load-correction scaling (I 2R) for partial-load infrared inspections in accordance with ANSI/NETA Maintenance Testing Specifications (MTS).
Units:
Results
Measured Delta-T (ΔTmeas): 0 °C
Corrected Delta-T at Full Load (ΔTcorr): 0 °C
NETA Severity Tier: Low Severity
Suggested Action: Investigate at next scheduled maintenance
Standard Guidelines
Standard Ref: ANSI / NETA MTS
Load Scaling Formula: ΔT × (Imax / Imeas)2
Priority Grading: Low / Green
Severity Status
LOW

Severity criteria are derived from ANSI/NETA Maintenance Testing Specifications (MTS). Load corrections assume standard resistance-heating proportionality (I2R). Always evaluate findings in conjunction with manufacturer ratings and electrical safety programs.
