The high voltage transformers are oil-filled, insulating
cylinders mounted on a steel base. The high voltage output is
available from a toroid on top of the cylinder. The BK130 also
utilizes a 35kV side output tap for liner testing.
The voltage regulator is an adjustable autotransformer,
air-insulated with a limit switch for .zero start. interlock. All
units are equipped with a high accuracy internal divider. The
low voltage arm of the divider feeds the panel-mounted
voltmeter. Total measuring accuracy is better than 1% of full
scale from 10%-100% of range.
The lower end of the high voltage winding is connected to
ground through a currentmeter circuit. Measuring accuracy
is better than 1% of full scale. A return terminal provides
precise measurement of actual current flow through the test
object to guard out capacitive leakage currents (guard
mode).
An adjustable electronic overload circuit, with a total
response time of less than 30 milli-seconds, provides protection
from flashovers and short circuits for the high voltage
transformer and for the test object.
