Sphere Gap Assembly

Sphere Gap Assembly are used for measuring AC, DC, or impulse voltages.

horizontal type range equipped with micrometer scale to read the gap up to the

accuracy of 0.1 mm. with 50 mm diameter ratings.

The sphere gap assembly is with a series water resist or in order to protect the

series against pitting Metal parts are hard chrome plated and insulated support

painted with anti tracking paints

Rod-Gap Apparatus

High Voltage AC/DC Set

Rod-Gap Apparatus, horizontal mobile apparatus manufactured to carry out

the experiments on the breakdown at high voltages between different types of

electrodes. To conduct the breakdown studies of electrodes up to 100 kV

AC/DC.

The moving electrodes with hard chrome plated micro-meter scale.

The apparatus is with plate, needle, and square tippled electrodes to

create uniform and non-uniform fields

High Voltage AC/DC Set, with the rectifier, resistance divider, and filters sed for

A.C and D.C (+ve and - ve polarity) tests on sphere gaps rod gaps, for finding

out the dielectric strength of solids and liquids.

High Voltage LaboratoryModel : HVL-10

Impulse Generators of 1.2/50 microsec, designed to test the strength of electric

power equipment against lightning and switching surges with capacity and

energy rating as :

100 kV, 100 joules

A powder coated, versatile motorized control panel supplied along with set

Impulse Generator

Electrolytic Tank

Corona Cage

Electrolytic Tank, used for field plotting by drawing equipotential lines of different

types of models.and to plot the electron trajectory in an electrostatic field.

The equipment is pentagraph type which makes an integral part of the tank and

the base. The parallel arms of the pentagraph can be moved in X and Y direction

The lower arm holds the probe which can be moved between the electrodes,

kept in the tank, to locate the equipotential points. Upper arm has a spring

loaded pencil holder and by pressing the top knob of the holder points can be

located on the drawing sheet with essential power supply and high impedance

digital meter

AC Voltage up to 50 kv

DC Voltage up to 70 kv
