Resistors built into the impulse circuit are wire wound and protected with heat shrink sleeve against mechanical damage.
Each resistor value has a specific colour for easy identification. These resistors have plug-in connection for quick and
The high impulse voltages are generated by charging Energy storage Capacitors to required high voltages and
discharging it through controlled firing system and wave shaping components.
Depending upon the design of the multi-stage impulse generator, various components like capacitors, resistors etc. are
decided to achieve the standard lightning impulse wave shape of 1.2/50 ìs as per IEC: 60060
