Utility frequency CT PT analyzer 2000V
The TAC750E primary injection test system replaces several individual testing devices. The CT PT analyzer reduces the costs for training and transport, and cuts down resting time. And it is the ideal test set for substation asset commissioning and maintenance. You can operate the analyzer via the integrated keypad and display screen.
The powerful testing device provides up to 2000V or 200A output. Its compact design makes it easy to transport and ideal for on-site testing.
This full featured product combines all of the metering CT test abilities of the popular TAC750 model with the additional advantage of also being able to perform both protection CT excitation tests as well as PT tests.
Light weight and portable, the CT PT TEST SET is housed in a ruggedized plastic case and is supplied with the necessary test cables and attachment accessories.
It features the following offline test capabilities:
Burden based CT and PT ratio and polarity check.
Excitation measurements of Protection Class CTs.
CT and PT secondary winding resistance.
CT and PT Burden test
CT and PT polarity check
Batch testing of metering CTs
Record download to USB Flash.
No need external booster, it can output 2000V voltage.
Output 200A current for primary injection method.
Draws 5% and 10% error curves.
LCD screen, keypad for operation
PC software for further analysis.
This full featured CT and PT test instrument lowers testing costs by being simple, fool-proof and fast. It’s capabilities allow utility personnel and test technicians to pursue the very important task of testing field based instrument transformers for measurement losses, faults or tampering.

High frequency questions
Why testing CTs?
Testing current transformers helps to detect installation related and in-service related problems, such as:
Installation related :
脴 Transportation damages
脴 Wiring errors
脴 Manufacturing defects
In-service related :
脴 Degradation of accuracy class
脴 Shorted turns
脴 Magnetized core
脴 Burden failures in secondary circuit
脴 Insulation material failure
What items should I test on current transformers?
You need to measure at least these items:
脴 CT ratio
脴 CT burden
脴 CT excitation curve (knee point)
脴 Polarity check
脴 Accuracy limiting factor (ALF) test
> CT winding resistance
脴 CT demagnetization and remanence
脴 CT voltage withstand test up to 2 kVAC
脴 Power/dissipation factor test up to 12kV/15 kV, 300 mA | with CP TD12/15
脴 IEC 61850 Sampled Values testing
