Product Q&A

Q:What is the measurement accuracy of the TTR tester?

The TTR measurement accuracy is 0.1% for ranges 0.8-3000, 0.2% for 3000-10000. Voltage measurement accuracy is 0.05% on the HV side and 0.1% on the LV side.

Q:How long does it take to complete a three-phase test?

The device features fast measurement speed, allowing a three-phase test to be completed within 60 seconds.

Q:Is the device portable and battery-operated?

Yes, it is a handheld device weighing about 3kg. It has a built-in high-capacity rechargeable Lithium-ion battery that supports over 800 continuous measurements on a single charge.

Q:What types of transformers can this tester measure?

It is suitable for Z-type, rectifier, electric furnace, phase-shifting, traction, Scott, and invert-Scott transformers. It can also measure transformers without nameplates and those with non-integral points.

Q:Does the device require external power for testing?

No, the test can be completed without any external power source due to the built-in high-capacity rechargeable battery.
