High-Precision Intermediate Transformers for No-Load, Load Loss & DVDF Testing (Up to 66 kV Class)
Precision in loss measurement demands complete control over your test bench voltage profile.

Engineered for a high-precision test bay dedicated to transformers up to 32 MVA, 66 kV class, this dual intermediate transformer system provides exact voltage matching for comprehensive load loss, no-load loss, and high-frequency induced overvoltage testing.

By stepping up from a standard 415 V source, this dual-unit configuration delivers seamless coverage across both high-resolution incremental steps and standard transmission test voltages:

1500 kVA Intermediate Transformer (Precision Loss Measurement)

Primary: 415 V

Secondary Multi-Tappings: 700 V, 1400 V, 2100 V, 2800 V, 3500 V, 4200 V, 4900 V, 5600 V, 6300 V, 7000 V, 7700 V, 8400 V, 9100 V, and 9800 V

Designed to optimize generator/regulator operating points and maximize instrumentation accuracy during impedance and loss testing.

500 kVA Intermediate Transformer (High-Voltage Excitation & DVDF)

Primary: 415 V

Secondary Dual Tappings: 11 kV & 33 kV

Engineered for high-voltage no-load excitation and multi-times induced overvoltage withstand tests.

Key Design Highlights:

Low Stray Losses & High Accuracy: Core and winding geometry optimized to maintain linear performance and minimize phase displacement errors in test measurements.

Enhanced Dielectric Integrity: Robust insulation grading capable of handling the high-frequency stresses of double voltage, double frequency (DVDF) induced potential testing.

Integrated Bay Operation: Built to function synchronously within a single testing console, minimizing changeover downtime between routine loss runs.

Custom engineering for NABL-accredited test laboratories, transformer manufacturers, and automated test bench developers.
