KV5-100 Mk4 5kV 100mA – High Voltage AC Test System

T&R Test Equipment is a market leader in the field of protection test equipment. The range includes primary and secondary current injection equipment up 6000A, voltage sources, micro-ohmmeters and high voltage test systems up to 100kV.

 

The KV5-100 Mk4 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 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 instrument is supplied in a compact and portable case with permanently connected test leads. The test leads are terminated in clips. The unit is designed for operation in conjunction with a suitable interlocked test enclosure or high voltage test area.

 

KV5-100 Mk4 Specification

Output
The main output on the unit is variable between 0 and 5kVac. The output is rated at 50mA continuously and 100mA for 5 minutes followed by an off time of 15 minutes.

 

Metering
The output voltage is metered by an analogue instrument with 0-3kV and 0-6kV scaling.

 

 

The output current is metered by a dual range analogue instrument with 0-10mA and 0-100mA ranges. The current trip may be set to 20-120% of the selected range in 20% steps.

 

 

Overload Protection
An electronic overload protection circuit is provided on the KV5-100 Mk4, backed up by a fuse. The trip current is user selectable, and allows values between 2mA and 120mA to be set. A trip condition is indicat-ed by an illuminated push button and an audible alarm.
Burn Circuit
When in circuit, the maximum short circuit current is limited to 100mA. When out of circuit, the maxi-mum short circuit current is approximately 2A.
Output connections
The KV5-100 Mk4 is provided with battery clips for connection to the object under test. The unit is de-signed to be operated in conjunction with an inter-locked test enclosure ensuring safety for the user.
Interlock Circuits
The unit has a zero volt interlock that prevents the output being energised unless the output control is in the zero position. An external interlock connec-tion is also provided, allowing the fitting of external emergency off buttons and test enclosure/cage door interlocks.

Supply Requirements
