The T 99/1 High Voltage Test Unit is a powerful portable device able to generate a DC voltage of up to 40 kV.

The Test Unit 40 kV T 99/1 is used for:

• Testing the disruptive strength of cables, cable fittings, equipment and installations with max. 40 kV
• Locating high-impedance and intermittent cable faults in low and medium voltage systems as per the decay method in conjunction with a time domain reflectometer
• Converting high-impedance and intermittent cable faults into low-resistance faults (burning)
• The shockproof enclosure of all high-voltage parts and the automatic discharging of the test object after shutdown / power failure ensure maximum protection for the operator. The short-circuit proof design and high output current of the T 99/1 40 kV test unit also make it suitable for cable fault location (Decay)

Salient Features of the T 99 / 1:

• Low weight (high voltage cascade embedded in insulating gas (SF6))
• Voltage continuously variable up to 40 kV
• Current measurement in three ranges: 200 A, 2 mA, 20 mA
• 12 V battery and 230 V mains operation
• Built-in discharge unit and automatic discharge after shutdown, power failure or upon pressing the discharge key
• Integrated timer, adjustable from 0 to 60 min.
• Controlled output voltage
• Over-current shutdown
