Technical Overview

The LQTT 150kV/60kVA Test Transformer delivers precision high-voltage output for diagnostic testing, compliance verification, and R&D applications. Engineered for IEC 60060 standards, its compact cylinder design ensures reliability in demanding environments.

Key Specifications

Performance Capabilities

1. Thermal Resilience

• Winding Temperature Rise: ≤65 K (after 8 cycles of 30-min ON / 60-min OFF)

• Oil Temperature Rise: ≤55 K

• Overload Tolerance:

• 100% rated current for 60 minutes (no insulation damage)

• 100% rated voltage for 60 minutes (winding/insulation integrity maintained)

2. Safety & Compliance

• Meets IEC 61010 safety standards for HV test equipment

• ≤12% impedance voltage for short-circuit protection

• ONAN cooling for zero operational downtime

3. Precision Metrics

• Ultra-low PD (<5 pC) for sensitive applications (e.g., cable, switchgear, and transformer testing)

• ≤5% waveform deviation ensures accurate harmonic analysis

Applications

• Certification Labs: Type tests per IEC 60270, IEEE 4

• Utilities: Preventive maintenance of grid assets

• Manufacturing: QA testing of insulators, bushings, cables

• Research: Dielectric strength validation

Why Choose the LQTT Series?

• Compact Design: 30% lighter than conventional 150kV transformers (<400 kg).

• Rugged Duty Cycle: 8 daily operational cycles without derating.

• Critical PD Sensitivity: Detect incipient faults in HV systems.

• Global Compliance: Built to IEC 60060-1/-2, IEC 61010 standards.

Technical Notes

Impedance Voltage (≤12%): Ensures safe short-circuit current limiting.
Waveform Deviation (≤5%): Guarantees pure sinusoidal output for accurate measurements.
ONAN Cooling: Eliminates forced-air noise; maintenance-free operation.
