Application

Steep waveform generator units are used to generate the steep wave front waveform. They comprises of one steep waveform generator gap unit and resistive voltage divider.


The gap unit consists of sphere gaps, transmission gear, capacitors and corona rings, which are mounted on the rectangular metal base.


The resistive voltage dividers are for indoor operation and applicable for the measurements for full and front chopped lightning impulses or impulses voltages with steep wave fronts. It can’t be served as a load capacitor for the impulse generator.

600kV Steep Waveform Generator Unit 

600kV Resistive Voltage Divider

Advantages and Features

(1)The gap distance is adjusted through the transmission gear, which can be controlled from the console.

(2)The gap distance and charging voltage should be adjusted to achieve the satisfactory steep front wave forms.

(3)The dividers are equipped with top HV electrodes to guarantee corona-free operation and castors at the bottom for easy movement.

(4)The high voltage dividers are housed in cylinders made from glass fibre enforced epoxy resin.

(5)The secondary unit at the bottom of the dividers consists of resistors of low inductance arranged in a coaxial design and is fitted with LEMO connector. The unit can be easily disassembled.
