ZXCT-H Current Transformer Field Calibrator
Ce Certified Hot Sell Easy Operation High Performance Current
Transformer Field Calibrator Full Automatic
Product introduction
The high-voltage electric energy measurement devices of power
plants and substations, and the electric energy measurement devices
of a large number of users, are related to the interests of power
generation, power transmission, power supply and multiple parties
of users. In order to ensure accurate measurement, the inspection
must be carried out in accordance with SD109 "Inspection
Regulations for Electric Energy Measurement Devices" and DL /
T448-2000 "Technical Management Regulations for Electricity
Measurement Devices".
ZXCT-H current transformer field calibrator was developed based on high-end testing technology, large-scale
electronic circuit design and in compliance with relevant national
regulations. It solves the problems of on-site verification of
current transformer and voltage transformer with high working
intensity and tedious operation. At the same time, the product has
reliable performance and powerful functions.
Features
1. The instrument also has a recursive method to measure the
current transformer error, which is convenient for the on-site
verification of the measurement device.
2. On-site verification of current transformers does not require
standard current transformers, current risers, load boxes, voltage
control boxes and high-current conductors. It uses extremely simple
test wiring and operations to achieve the verification of current
transformers, greatly reducing the work The intensity and working
efficiency are improved, which is convenient for the on-site
verification of transformers.
3. The instrument has a standard voltage transformer equivalent to
the same transformation ratio of the measured current transformer.
Its accuracy can reach 0.05 level, and the transformation ratio and
no-load error of the measured current transformer can be accurately
measured. Then combine the test results of impedance and admittance
to calculate the error of the transformer.
4. Adopt different frequency power supply test close to power
frequency to prevent on-site power frequency electromagnetic
radiation and series interference.
5. Wide measuring range, can reach 5A / 5A ~ 25000A / 5A or 5A / 1A
~ 6300A / 1A.
6. With the function of current transformer transformation ratio
and secondary winding internal resistance test.
7. Adopt 800 × 600 high-resolution large-screen color liquid
crystal display, with humanized interface and operation design, and
use the touch screen to assist the operation, making the operation
more convenient and fast.
8. Using precise software algorithms, the accuracy of measurement
data is further improved.
9. It has the intelligence to judge the external wiring status, and
prompts the wiring error, transformation ratio, polarity error,
etc.
10. Automatically round the test data and judge whether it is out
of tolerance. The out-of-tolerance data is displayed in orange and
the out-of-tolerance is displayed at the lower right corner of the
window.
11. Directly issue on-site verification conclusions, qualified or
out of tolerance.
12. Large-scale memory can store up to 1000 field test data.
13. Use RS232 or USB interface to connect computer to print data
certificate.
14. The engineering plastic mold chassis is used to prevent shock
and pressure to ensure the safety of on-site operators and
equipment.

Note: The current transformer with a secondary current of 1A can be
converted to 31500A / 1A by the method of equal-ampere turns
measurement. Other test methods for the current transformer ratios
that do not appear in the table are as follows:
Use the equal ampere-turn method to test the current transformer,
for example: you need to test the 1000A / 5A transformer, please
pass the test wire of the instrument through the two turns of the
current transformer, and then test A current input is only 500A.
This test method does not affect the validity of the transformer
test data.
Similarly, other transformation ratios use the following processing
methods:
| Rated once (A) | Number of turns | Instrument primary current (A) |
| 80 | 2 | 40 |
| 120 | 2 | 60 |
| 8000 | 2 | 4000 |
