Technical
Details
TRANSFORMER
: A double wound step up
transformer is the most important part of the spark tester. The
transformer is so designed that the input current remains within
set limit in order to protect the transformer against short
circuit. The transformer is made of CRGO core, wound with very
high quality super enameled copper wire and polyester film/paper
is used for insulation. VOLTAGE
CONTROL
: A step-less auto-transformer
is used for controlling the output form zero to maximum. The
auto transformer has built in arrangement for zero start
interlocking. INPUT
VOLTAGE
: 230 Volts single phase 50Hz.
AC Supply
OUTPUT VOLTAGE
: Up to 40 KV CAPACITY : Up to
5 KVA
METERING
: Voltmeter is provided in L.T.
side, to indicate HV Output.
ELECTRODE
: Brass ball chain electrode is
having a number of balls to ensure 100% contact with the coated
wire which passes through the electrodes.
CONTROL
: Knob to control the AC output
from zero to maximum.
PROTECTION
:
-
ON-OFF
switch with fuse provided to protect the unit in case of
short circuit. HV will not actuate unless variance is
at zero position.
-
The
HV trips off automatically if anybody tries to reach ball
chain.
-
FAULT
INDICATORS : Audio Alarm is provided to indicate fault which
passes through ball chain.
FAULT
COUNTER :
An electro-magnetic counter is provided to count the faults with
resetting knob.

OPTIONAL
:
-
Guide
Rollers with strong frame.
-
Tripping
circuit to cut off the HT supply in case of faulty
cable/bare conductor passing through electrode.
-
Sensitivity
