Measuring Spark Gaps

 

Measuring Spark Gap are widely used for high voltage measurement, calibration & during chopped wave impulse tests. We offer these Measuring / Chopping Gaps with sphere diameters 100mm, 250mm, 500mm, etc. These Measuring / Chopping Gaps are designed in compact size and are light in weight, which make them portable. We offer these Measuring / Chopping Gaps at very reasonable prices.

We also manufacture Multiple Chopping Gaps (Electro magnetically operated and also pneumatically operated) for integration with our Impulse Generators for chopping tests.

The sphere spark gap is composed of two spherical metal electrodes, having the same diameter D, mounted vertically in air at an adjustable distances: the values of the disruptive discharge voltage between the spheres, when one of these is grounded, depends on the distance S and on the Diameter D.

Such values for AC, DC and impulse voltage are reported on Tables in the national and international standards, together with the main construction data and the limits of distances from the ground, from the walls and from foreign bodies, necessary to avoid field distortion between the spheres. It is important to take into account the above prescriptions in order to ensure the compliance with the standard values within the range ± 3%.

Optionally a sphere with a trigatron device for the production of chopped wave can be supplied.
