Impulse Generator

Dragonfly Tech Solutions, Bengaluru offer wide range of Impulse Generators. Impulse Voltage Generator (Model: IGX-203) is specially designed for testing MCBs, LT Panels or any other items having low load capacitance.

All the controls / measuring circuits are provided with proper HF filters / surge suppressors where ever necessary. The test voltage can be continuously varied from 3kV to 20kV. Since the range of test voltage varies from 3 kV to 20kV, a specially designed electro mechanical capacitor discharge system is envisaged. So there may be a very small contact bouncing at lower voltages.
