T&R KV5-100 HV AC Test System for Testing Insulation Systems
The KV5-100 MK3 Test System is a general purpose, high voltage test instrument designed for testing insulation systems and the measurement of breakdown voltage on electrical plant and components. The unit has an output voltage adjustable from zero to 5kV 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 with a dual-scale marking of 0-3kV and 0-6kV. Load current is metered by a second analogue instrument with 0-10 scale marking. Two current ranges are selectable: 0-10mA and 0-100mA.
The test object and output are protected by an adjustable current trip linked to the current metering range. The trip level may be set to 20-120% of the current metering range on 20% steps.
Breakdown of the test object is both audibly and visibly indicated. The alarm must be manually reset after a trip condition before testing can be resumed.
The KV5-100 MK3 Test System is supplied in a compact and portable case with permanently connected test leads. The test leads are terminated in crocodile clips. The unit is designed to be used in conjunction with an interlocked test enclosure.
