1. The transformer comprehensive test adopts the integrated
structure design, the appearance is exquisite and unique, all the
instruments are inlaid and highly integrated.
2. The system is an intelligent test circuit with 33kV voltage and
below grade (22kV,11kV, etc), Single and three phase transformer
testing for 2500KVA maximum capacity. One-off wiring system,
complete DC insulation resistance, absorption, winding resistance,
voltage ratio measurement and connection symbol verification and
no-load loss and no-load current, short circuit impedance and load
loss measurement, induced overvoltage withstand test, temperature
rise test, no-load loss and no-load current measurements at 90% and
110% of the rated voltage, short-time over load test (for
oil-immersed transformer), transformer zero-sequence impedance
test. Dielectric loss factor (tanδ) measurement (for oil-immersed
transformer), capacitance measurement of winding to ground and
between windings are completed by an independent test system.
3. Using the intelligent capacitor compensation controller, the
capacitor can be compensated automatically according to the power
factor of the system.
4. Can be docked with backstage intelligently, can be directly used
to scan the code gun and other tools directly read parameters.
5. The transformer test system integrates test wiring, display,
data acquisition, analysis and processing, measurement and control,
storage, printing and protection. The whole test process is
completed automatically. It has the outstanding advantages of high
efficiency and high precision.
6. The transformer test system adopts full computer operation and
displays parameters such as three-phase voltage and current at the
same time. All test data are displayed in real time (locked) on the
screen, which avoids errors caused by parallax, conversion,
calculation and other in the test process. Make the test more
accurate. In particular, it completely solves the difficulty of
operators reading and reading multiple meters and recording
multiple sets of data at the same time, so as to ensure the
accuracy and reliability of test data.
7. The method of automatic storage is adopted for data processing.
All test data are filled into the corresponding database in real
time, so as to avoid manual transcribe and record process and
ensure the truth and reliability of the data.
