Division 02 · Core Electrical-Test Division · Energization Gate

Electrical Testing

The core electrical-testing division of the AGL Testing & Commissioning Manual. Division 02 verifies the electrical integrity, continuity, insulation, resistance, polarity, voltage, current, power, circuit connections, transformer circuits, connectors, control circuits, and auxiliary supplies of the installed AGL system — before any functional or system-level commissioning begins.

Sequence: Prepare → Isolate → Verify Safe → Test → Record → Evaluate → Accept/Reject → Report. Test methods, test voltages, permissible limits, discharge requirements, and acceptance values are always taken from the applicable project specification, approved test procedure, equipment manufacturer requirements, and applicable standards — this division defines the testing scope, not the numerical acceptance limits.

Testing Philosophy

Every topic in this division follows the same underlying sequence, whatever the circuit or equipment under test — and every result is carried through to a formal evaluation and acceptance decision, never accepted on the strength of a recorded number alone.

Master Electrical Testing Sequence

Division 02 is worked as a staged sequence rather than a single pass — each group below builds on the one before it, and the division closes only once evaluation and acceptance are complete.

GroupWhat It Confirms
A — Insulation & ContinuityCable and equipment insulation is intact, and the intended electrical path exists without an unintended open circuit
B — EarthingThe installed earthing system, earth electrodes, and protective bonding paths meet resistance and continuity requirements
C — Polarity & ResistanceConnections are correctly oriented, and circuit/cable resistance is consistent with design expectations
D — Electrical MeasurementsRequired supply voltage, current, power, and phase configuration are present and correct at specified test points
E — Cable & Termination TestingInstalled cables, joints, and terminations are electrically and mechanically sound
F — Circuit & Equipment VerificationPrimary and secondary circuits, transformers, and connectors are electrically verified before energization
G — Control & AuxiliaryControl circuits and auxiliary supplies are electrically sound ahead of functional testing
H — Evaluation, Acceptance & ReportingEvery result is evaluated against an approved criterion, formally accepted or rejected, and traceable to a test report
