GD Tube Tester

This is a specialized machine for testing Pouyet / Krone/ E 10B IPM / GD tube. If GD is not proper then exchange line cards can not be protected from surge voltage. Modulated signal equivalent to lightening signal is internally generated and is applied to GD tube.This will force the gas inside the GD tube to discharge and we get alarm from the unit. Individual section of GD tube like A or B limb can be tested. Similarly we have tester for testing 10 Ch GD tube magazine of Krone and Pouyet type.

• Easy to use operation. Any layman can use it
• Checks Pouyet / Krone / E-10B IPM / GD tube
• Checks individual limb
• Internally generates minimum gas discharge signal without damaging tube
• All types of fuses tested with their respective min signal strength
• For krone type ordinary fuse is also tested
• Very low power requirement. Mains operated
• Compact and light weight
• Direct detection
• Use of high speed circuitry

Insert the IPM/GD Tube into the appropriate socket. Select A or B limb. Apply Low signal by pressing "Low" button. Then for good GD tube gas will not discharge and we will not get any buzzer. Then press "High" button . This time high modulated signal will be applied. We should get buzzer for good tube. Repeat for other types of GD tubes.
