Megger VIDAR - Vacuum Interrupter Tester
The Megger VIDAR is a precision diagnostic tool used to test vacuum interrupters in medium- and high-voltage circuit breakers. It applies a controlled DC high voltage to evaluate the vacuum chamber's insulation integrity, ensuring reliable operation in power substations without dismantling the breaker.
Features & Benefits
- Selectable test voltage range from 10 to 60 kV DC, customizable for different needs
- Instant pass/fail indication via green/red lamp simplifies result interpretation
- Lightweight design (~7 kg) offers excellent portability for field use
- Safe two-hand operation with HV warning indicators enhances user safety
- No need to remove or dismantle the vacuum interrupter, enabling quick and non-intrusive testing
Material & Build
The instrument is built with durable, high-quality materials designed for rugged field conditions. It is powered by 115/230 V AC mains supply, featuring reliable electronic components to ensure accurate and repeatable measurements over time.
