LQTT Series 150kV/350kVA High Voltage Test Transformer

Engineered for demanding high-voltage (HV) testing applications, the LQTT 150kV/350kVA test transformer delivers reliable performance in laboratories, manufacturing facilities, and field operations. Its robust cylinder-type construction ensures optimal insulation integrity, making it a critical tool for dielectric withstand testing, cable/transformer validation, and R&D.

Key Technical Specifications

Performance & Durability

• Thermal Resilience:

• Continuous operation at 80% rated current/voltage.

• 60-minute full-load operation (100% rating) without derating.

• Max temperature rise: 65K (winding), 55K (oil surface).

• Compliance-Ready:
  Designed to align with IEC 60076, IEEE C57.12.00, and other international HV testing standards.

Critical Applications

• Dielectric withstand testing (hipot) of cables, switchgear, and transformers.

• Power frequency AC voltage tests on insulators and bushings.

• Routine maintenance testing of HV infrastructure.

• Quality assurance in manufacturing of electrical equipment.

Safety & Reliability Features

• Cylinder-Type Tank: Minimizes corona discharge, enhances insulation stability.

• ONAN Cooling: Self-cooling design for extended operational safety.

• Low Noise (<60 dB): Suitable for indoor labs and noise-sensitive environments.

• Precision Measuring Winding (100V): Enables accurate external monitoring and control.

Why Choose the LQTT 150kV/350kVA Transformer?

• Engineered for Precision: ≤0.5% dielectric loss and ≤3% waveform distortion ensure test accuracy.

• Rugged Design: Industrial-grade construction for harsh environments.

• Operational Flexibility: Supports both short-duration peak tests (100% load) and sustained operations (80% load).

Industry Note: Regular calibration and oil testing are recommended to maintain compliance with IEC 60270 (partial discharge) and IEC 60137 (bushings).
