Transformer turn ratio tester(TTR)
The turns ratio or voltage ratio test of the running transformer
can check the correctness of the turns ratio of the transformer,
the condition of the tap changer, whether the transformer is
short-circuited between turns, and whether the transformer can
operate in parallel. The operation is simple and intuitive. It
adopts a three-phase precision inverter power supply, and the test
is fast and accurate. It can test both single-phase and three-phase
simultaneously.
For the three-phase transformation ratio test, the transformation
ratio value, error, and tap position are automatically calculated.
For the three-phase group test, the transformation ratio value,
error, tap position, and group number are automatically calculated.
In addition, it can also measure the angle between phases.
★With Z-type, rectification, grounding, electric furnace, phase
shift, balance, Scott, and reverse Scott variable measurement
functions.
★With reverse connection protection, turn-to-turn short circuit
protection, tap changer failure protection, output full short
circuit protection.
★Modular LCD display, Simple operation according to on-screen
instructions.
★print output, U disk interface, and RS232 interface, which is
convenient for paperless office.
★automatically calculated transformation ratio value, error, tap
position, and group number of three-phase group test
