Transformer Testing
Transformer TTR Simulator
Configure a padmount-style transformer, review the safety hold point, run transformer insulation checks, then practice TTR lead placement from the same work area.
Megger H winding to ground
Run insulation checks before ratio testing.
Insulation Check
Megger H winding to ground
This checks high-side winding insulation to the grounded tank/core reference. Remove arresters, PT/control paths, and grounds only per approved procedure.
Expected
Red on H winding group. Black on Tank / ground.
Tool
Megger/AEMC insulation tester at 2500V DC training profile.
Safety
Before this simulator, LOTO and live-dead-live are complete. Neutral/ground links must be lifted or isolated as required. Discharge windings before moving leads.
Padmount Work Area
Transformer Front Cabinet
Left compartment is high side. Right compartment is secondary. Terminal sets change with the selected connection.
Expected for Current Objective
Red: H winding group. Black: Tank / ground.

Safety / Isolation
Before the simulator starts, perform LOTO and live-dead-live in the field: prove on a proving unit or known live source, test absence of voltage, then prove again. For this nameplate, use a high-voltage live-line meter / wand during that real-world hold point.
Test Equipment
Mission Steps
Mistakes Tracked
No mistakes yet. A clean transformer run starts with voltage proof, isolation discipline, correct test equipment, and correct winding paths.
Readings / Safety Checks
Prove absence of voltage, run transformer megger checks, then switch to a TTR set and run ratio shots.
