KV 30 - 40, high voltage test sets
The KV15-80 and KV30-40 high voltage test sets are general purpose test
instruments designed for testing insulation systems and the measurement of
breakdown voltage on electrical plant and components.
The units have an output voltage variable from zero to 15kV (KV15-80) or
30kV (KV30-40) with accurate metering on both the output voltage and
current. A zero-voltage interlock is provided, ensuring that the output may
only be energised with the voltage control at zero.
The output voltage is metered by a large, linear analogue instrument
marked 0-20kV on the KV15-80 and 0-40kV on the KV30-40. Both units have a
x0.5 range on the voltmeter giving a full scale of 10kV or 20kV
respectively. Load current is metered by a second analogue instrument with a
full scale of 100mA (KV15-80) or 50mA (KV30-40). A ¸10 range is provided on
both units, allowing the full scale on the current metering to be reduced by
a factor of 10. The test object and output are protected by an adjustable
current trip. The trip level may be set to 10-110% of the rated output in
10% steps. Breakdown of the test object is visibly indicated. The unit must
be manually reset after a trip condition before testing can be resumed.
The unit is supplied in a compact, portable case with a permanently
connected 2 metre long HV output lead.
The KV30-40 is part of a range of high voltage test systems available
from Test and Measurement Hire Limited.
