T&R KV5-100 mk3 High Voltage AC Test System

The T&R KV5-100 mk3 high voltage test set is a general purpose 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 of the KV5-100 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 by the T&R KV5-100. The alarm must be manually reset after a trip condition before testing can be resumed. FEATURES Continuously variable output voltage 0-5kVac. Variable trip circuit. 12mA and 20-120mA. Output voltage and current metering. Visual and audible indication of test piece failure. Compact lightweight instrument. Burn feature giving 100mA maximum current on short circuit. Key operated switch preventing unauthorised operation. Complies with the testing requirements of BS1363. T&R KV5-100 mk3 Specifications Output Output Range Variable from 0 to 5 kV AC. Output Rating 50 mA continuous 100 mA for 5 minutes followed by off time of 15 minutes. Metering Ranges 0 - 3 kV 0 - 6 kV. Accuracy +1.5% of FS. Trip Current Range 10 mA 100 mA. Accuracy +3% of FS. Overload Protection Types Electronic overload protection circuit Fuse. Trip Current User-selectable from 2 mA and 120 mA. Trip Condition Indicated by illuminated push button and audible alarm. Burn Circuit Short Circuit Current Limit 100 mA (In Circuit) Approx 2 A (Out of circuit). Output Connections Safety Battery clips Designed to be operated in conjunction with an interlocked test enclosure. Interlock Circuits Type Zero interlock that prevents the output being energised unless the output control is in the zero position. Also includes external interlock connection, allowing the fitting of external emergency off buttons and test enclosure/cage door interlocks.
