Each VON Model C test set consists of a corona free high voltage
base cabinet, a control box, a sectionalized discharge stick,
and a protective output resistor.

Each
High Voltage Base Cabinet Contains:
- A
625 volt amp, 110v to 20kv or 220v to 20kv (Option E), air-insulated,
epoxy-impregnated, high voltage transformer.
- A
Cockcroft-Walton voltage multiplier circuit specially engineered
for this particular application.
- A
kilovoltmeter multiplier resistor connected directly to
the high voltage guard circuit. This gives direct voltage
measurement of the high voltage output.
- A
magnetically and electrostatically shielded and guarded
output meter assembly in the HIGH VOLTAGE LEAD with ranges
of 0-100 microamp and 0-1 milliamp. Each meter is individually
protected by a special bypass circuit. Range changing is
accomplished automatically. Special ranges can be furnished.
This assembly is replaced by a multirange 0-10 microammeter
in the control box in the Model CG. The overlapping ranges
are 0-10/30/100/300/1,000/3,000/10,000/30,000 microamps.
- A
neon protective tube to limit the kilovoltmeter circuit
to 50 volts.
- A
high voltage hot guard (non-measured) connection when current
metering is provided in the high voltage lead.
- A
cold guard (non-measured) connection when current metering
is provided in the ground return lead. (Model CG and units
with otion D)
- A
metal ball suitable for corona free operation at maximum
voltage is provided on the output terminal for use on top
of the protective output resistor.
These
units can be extended to 500KV with VON topping units. The maximum
output voltage level is limited by the required output current
at that voltage.

Sectionalized
Discharge Stick:
Units
rated 50kv, 60kv, and 100kv have a stick with an overall
length
of 39" (99cm) and consist of two insulating sections,
one resistive section(4
megohm for 50kv & 60kv, 7.5 megohm for 100kv &
120kv units), one hook,
one insulating shield, and one ground connecting strap. Units
rated 170kv have
a stick with an overall length of 65" (165cm) and consist
of three insulating
sections, two resistive sections-7.5 megohms, one hook, one
insulating shield,
and one ground connecting strap.
