Lesson 3 • Equipment Data Sheets and Specifications

Explains how to extract nameplate data, ratings, and test requirements from specifications. Links manufacturer data to commissioning acceptance criteria.

Lesson 1 • Voltage and Current Measurement

Teaches safe measurement of AC and DC voltage, current, and power factor. Provides the foundational measurement skills used in every subsequent test procedure.

Lesson 2 • Power Quality and Harmonic Analysis

Introduces power quality analyzers, harmonic spectrum capture, and distortion limits. Prepares students to diagnose power quality issues encountered during commissioning.

Lesson 3 • Instrument Selection and Calibration

Covers instrument categories, accuracy classes, and calibration traceability requirements. Ensures measurements meet the precision demanded by commissioning standards.

Lesson 4 • Earth Continuity and Ground Testing

Covers earth electrode resistance measurement and protective conductor continuity testing. Validates the earthing system before energisation of any equipment.

Lesson 1 • Cable Termination and Joint Verification

Addresses inspection of terminations, joints, and stress cones for correct installation. Ensures connection quality that prevents premature cable failures in service.

Lesson 2 • Continuity and Loop Resistance Testing

Teaches conductor continuity, loop impedance, and resistance measurement methods. Confirms correct cable installation and adequate fault current capacity.

Lesson 3 • Pre-Installation Cable Inspection

Covers drum testing, sheath integrity checks, and storage condition verification. Prevents defective cables from being installed and causing commissioning failures.

Lesson 1 • Energisation and Load Testing

Guides the controlled energisation sequence and initial load application to switchgear. Confirms stable operation under real operating conditions before handover.

Lesson 2 • Switchgear Mechanical Inspection

Covers visual inspection, racking mechanism checks, and busbar torque verification. Establishes the physical baseline before any electrical testing begins.

Lesson 3 • Busbar and Insulation Testing

Applies insulation resistance and hipot tests to busbars and compartment insulation. Validates dielectric integrity of the complete switchgear assembly.

Lesson 4 • Circuit Breaker Testing

Teaches contact resistance, timing, and minimum pickup current tests for circuit breakers. Confirms breaker performance against manufacturer and protection coordination requirements.

Lesson 1 • Transformer Pre-Energisation Checks

Covers oil sampling, winding resistance, turns ratio, and vector group verification. Establishes transformer health before any voltage is applied to the unit.

Lesson 2 • Power Factor Correction Commissioning

Commissions capacitor banks, automatic power factor controllers, and harmonic filters. Validates reactive power compensation performance at the point of common coupling.

Lesson 3 • On-Load Tap Changer Commissioning

Tests OLTC mechanical operation, contact resistance, and automatic voltage regulation. Ensures voltage regulation functions correctly under varying load conditions.

Lesson 1 • Overcurrent and Earth Fault Relay Testing

Tests pickup, time-current characteristics, and instantaneous elements of overcurrent relays. Confirms relay response matches the protection coordination study settings.

Lesson 2 • Differential and Distance Relay Testing

Applies secondary injection to verify differential bias characteristics and distance zone reaches. Ensures correct operation for transformer and line protection schemes.

Lesson 3 • Current and Voltage Transformer Testing

Covers CT ratio, polarity, excitation, and burden tests plus VT ratio and polarity checks. Validates the measurement inputs on which relay decisions depend.

Lesson 4 • Protection Coordination and System Testing

Validates relay coordination across protection zones using primary injection and end-to-end tests. Confirms the complete protection scheme operates correctly as a system.

Lesson 1 • Motor Protection Relay Verification

Tests thermal overload, phase loss, and locked rotor protection for motor circuits. Ensures motor protection operates correctly before the motor enters service.

Lesson 2 • Motor Pre-Commissioning Checks

Covers insulation resistance, winding resistance, bearing inspection, and alignment verification. Establishes motor health and mechanical readiness before first energisation.

Lesson 3 • Motor Starting and Running Tests

Monitors starting current, acceleration time, and steady-state current during motor trials. Confirms motor performance matches load requirements and nameplate ratings.

Lesson 4 • Control System and Interlock Testing

Verifies PLC logic, HMI displays, and process interlocks through structured functional testing. Confirms automation system behaviour matches the control philosophy document.
