TT 1
telescope voltage tester for trams up to 1000 V AC / DC 
The warranty period is 3 years.
No. Our telescopic voltage testers are complete testing systems that can be used immediately. The devices include the display unit, the ground connection and a telescopic system to achieve the desired test height.
No. The use of the telescopic voltage testers is very versatile.
In addition to testing overhead lines, the devices can also be used to test overhead lines in the 1k V and 10 kV energy supply range. Furthermore, the voltage testers are used to test capacitors in compensation systems.
The area of application also includes testing busbars in switchgear.
The variable test electrode allows the devices to be optimized for different applications.
No. The safety distances of the devices are such that they can be used safely even when pushed together. This also applies to the 36 kV versions.
Yes. Tietzsch telescopic voltage testers are basically designed as two-pole voltage testers. Therefore, the voltage is always checked between the + electrode and the ground terminal. Testing with just one electrode, as with capacitive measuring systems, is not possible.
The display threshold cannot be set by the user.
We have set the following display threshold for our telescopic voltage testers:
TT 1 = 250V AC/DC
TT 3 = 400V AC/DC
TT 36 = 1200V AC/DC
However, due to the diverse applications and railway systems, other display thresholds are possible at any time for the telescope systems. Please ask us about this.
