Precision Wave-shaping and
Measurement for HV Test Systems
High Voltage Impulse Resistors are specialized components used in impulse voltage and current testing systems to accurately shape and control the impulse waveform. These resistors play a critical role in generating standard lightning and switching impulse waves by forming the front and tail shaping networks of an impulse generator circuit.
Carona Power designs and manufactures precision impulse resistors engineered to withstand high voltage stress, high energy discharge, and repetitive impulse operation. Our resistors ensure reliable waveform performance, stable resistance values, and long service life under demanding high-voltage test conditions.
