HIGH VOLTAGE AC TEST SYSTEMS KV30-40D MK2

The KV30-40D mk2 series 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 10kV (KV10-120), 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 and current are metered by large, accurate true RMS digital meters. The meters are backlit and have a digit height of 19mm.

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.

A pre-selectable test timer is provided for timed tests of 5, 10, 15, 20, 30 seconds, 1, 2, 3 or 5 minutes. An alarm sounds when the test time has ended.

The units feature automatic mains voltage selection and an external 24Vdc interlock circuit for connection of emergency off switches aned enclosure interlocks.

The unit is supplied in a compact, portable case with a permanently connected 2 metre long HV output lead. An ES30 earthing stick is also supplied as standard.

KV30-40D mk2 Specification

Supply Requirements

115V/230V±10% auto-selecting

50/60Hz 1ph 1200VA max

Output

The output of the KV30-40D mk2 is supplied via a permanently connected partially screened high voltage cable.  This stows in the lid for transit along with the ES30 earthing stick

The output of the KV30-40D mk2 is rated at 40mA on a duty cycle of 5 minutes on/15 minutes off or 20mA continuously. These ratings are based on an ambient temperature of 25°C.

Metering

The output voltage and current are metered by large, accurate true RMS digital meters.  The meters are backlit and have a digit height of 19mm.

Test Timer

A pre-selectable test timer is provided for timed tests of 5, 10, 15,

20, 30 seconds, 1, 2, 3 or 5 minutes.  An alarm sounds when the test time has ended.

Overload Protection

Two overload protection circuits are provided on the units.  The first is user selectable, and allows trip currents between 10% and 110% of the rated output to be set.    A trip condition is indicated by an illuminated push button and an audible alarm.   The second trip circuit is a magnetic circuit breaker operating on the primary of the HV transformer.   This operates on large overloads (such as flashovers).

Protection and Safety

In addition to the output protection the input and control supplies are protected by fuses.

All units are designed to meet the requirements of BS EN61010.

An earth terminal is provided on the transformer which must be connected to a low impedance local earth.

An emergency stop will cut all power to the output, when activated.
