Operational Advantages vs Competitors

Technical Insights

Why ≤5% Waveform Matters:
Ensures pure 50Hz sine wave for accurate power factor/tan-delta measurements - critical for cable aging assessment.

ONAN Cooling Superiority:
Eliminates fan failures in dusty environments. Oil volume: ≈300L (est.) for 55K thermal stability.

PD Testing Precision:
<5pC sensitivity detects microscopic voids in epoxy insulators at 150kV - prevents in-service failures.
