The Heavy-Duty Variable Frequency Resonant Testing Device is the industry benchmark for testing massive electrical infrastructure. Specifically designed to meet the rigorous demands of power transmission construction and preventive maintenance, this system utilizes series resonance principles to perform non-destructive AC withstand voltage testing on power transformers, GIS, and 110kV-500kV cables. Featuring a robust control console, dry/epoxy excitation transformers, and high-linearity reactors, it guarantees reliable operation under harsh industrial environments.
Transformer Insulation Verification: Verifies main and longitudinal insulation of power transformers at rated frequencies (45Hz–65Hz).
Capacitive Load Adaptability: Handles large capacitive loads seamlessly without overheating or waveform distortion.
Smart Digital Control Console: Features manual and automatic tuning modes, real-time waveform display, and safety interlocking.

Q1: How do I select the correct capacity (kVA) for my testing requirements?
A1: Capacity selection depends on your maximum test voltage ($V$), maximum capacitance of the test object ($C$), and test frequency ($f$). Our engineering team offers free calculation and system configuration services based on your project specifications.
Q2: What is the warranty period for this testing device?
A2: We provide a standard 12-month global warranty with lifetime technical support and spare parts availability.
