100% Factory Acceptance Testing (FAT)

Quality Assurance System & Laboratory Testing

Every electrical panel manufactured at Panel Electro undergoes rigorous routine dielectric, insulation resistance, busbar torque, and operational functional tests before dispatch.

Routine TestIS 8623 / IEC 61439-1 Section 11.9

High Voltage Dielectric Test (HV Test)

2.5kV AC voltage is applied for 60 seconds between all power phases connected together and frame earth, as well as between individual phases.

Lab Equipment Used:Calibrated Automatic 0-5kV AC Dielectric Test Set

Acceptance Criteria: No breakdown, flashover, or leakage current exceeding 10mA.

Routine TestIS 8623 / IEC 61439-1 Section 11.3

Insulation Resistance Test (IR Megger Test)

1000V DC voltage is applied between power phases, neutral, and earth for 1 minute before and after high voltage testing.

Lab Equipment Used:Digital 1000V DC Insulation Resistance Tester (Megger)

Acceptance Criteria: Insulation resistance must be greater than 100 Megohms (>100 MΩ).

Routine TestManufacturer Standards & IS 8623

Busbar Torque Verification Test

100% of busbar joint high-tensile bolts (M8, M10, M12, M16) are torqued to specified N-m settings and sealed with paint mark.

Lab Equipment Used:Calibrated Digital Torque Wrench

Acceptance Criteria: Tightening torque complies with target values (M10 @ 45Nm, M12 @ 85Nm, M16 @ 190Nm).

Special Inspection TestIS 101 / ASTM D7091

Paint & Powder Coating Thickness Test

Dry Film Thickness (DFT) is measured at 10 random points across door panels, side sheets, and frame structures.

Lab Equipment Used:Digital Magnetic Coating Thickness Gauge (Positector 6000)

Acceptance Criteria: Powder coating thickness consistently between 80 and 120 microns.

Routine TestIEC 61439-1 Section 11.5

Earth Continuity Test

25A DC current is injected between the main earth copper busbar and all metallic doors, covers, and switchgear handles.

Lab Equipment Used:Micro-Ohm Meter & 25A Earth Bond Tester

Acceptance Criteria: Resistance to earth must not exceed 0.05 Ohms (< 0.05 Ω).

Routine TestIS 8623 / Client Schematic

Control Wiring & Secondary Functional Test

Control supply is energized to test breaker closing/tripping, interlocks, AMF auto-crank, PLC IO loops, and alarm annunciators.

Lab Equipment Used:Auxiliary AC/DC Power Injection Bench & Multi-meter

Acceptance Criteria: 100% functional match with approved control schematics and zero wiring defects.

Raw Material Traceability

Incoming Quality Control (IQC)

Quality begins at raw material arrival. 100% of electrolytic copper bars, CRCA sheets, and bought-out switchgear are inspected for material test certificates (MTC), thickness tolerances, and chemical composition before entering the production queue.

99.9% Copper Conductivity & Hardness Testing
CRCA & GI Sheet Thickness Gauge Verification
Switchgear Batch Counterfeit & Seal Verification

Included Factory Acceptance Test (FAT) Certificate

Every dispatched panel includes a signed and sealed Quality Inspection Certificate containing:

✓ Measured HV Withstand Leakage Current (mA)

✓ Insulation Resistance Value (>100 Megohms)

✓ Busbar Bolt Torque Calibration Seal Mark

✓ Powder Coating Dry Film Thickness (80-120 Microns)
