1. Understanding Electrical Panel Testing

Electrical panels, also known as switchboards or distribution boards, control and distribute electrical power in industrial and commercial settings. Testing these panels ensures their safety, compliance, and functionality. Key testing parameters include:

Continuity Testing: Verifying uninterrupted electrical flow across circuits.
Insulation Resistance Testing: Measuring insulation integrity to prevent leakage currents.
High-Potential (Hi-Pot) Testing: Ensuring no dielectric breakdown under high voltage.
Functional Testing: Validating proper operation of relays, breakers, and control units.

2. Challenges in Manual Testing

Manual testing involves using handheld instruments and requires skilled technicians to measure, analyze, and log data. Common challenges include:

Human Errors: Misinterpretation of readings and errors in documentation.
Time Consumption: Testing large or complex panels can take hours or even days.
Repeatability: Ensuring consistent results across multiple panels is difficult.
Safety Risks: Working with high voltages poses significant risks to technicians.
