Transformer CT Current Transformer Testing Equipment On - Site
Calibrator
Introduction
The device is developed with high-end testing technology,
large-scale electronic circuit design and accord with national
related protocol . It has solved the problem of big working
intensity, trivial operation when on site test current transformer,
voltage transformer. Meanwhile the product has a reliable
performance, and powerful functions.
Features
1. Recursive method to measure current transformer error
2. Test without standard current transformer, Load Box, adjustable
control box and primary cable. Using extreme simple wire connection
and operation to test,
3. Accuracy 0.05S, measure accurately the turn ratio and load
error, Then combined with the impedance and admittance test results
to deduce the transformer error.
4. Variable frequency power supply with frequency close to power
frequency, which can prevent power frequency electromagnetic
radiation and series interference.
5. Wide Measurement range: 5A/5A~25000A/5A or 5A/1A~5000A/1A.
6. Current transformer turn ratio, secondary winding resistance
test function.
7. With 800×600 high resolution and large screen LCD, humanized
interface
8. Precise software algorithm further improved the measuring
accuracy
9. Intelligently judge the external connection status, give tips of
errors
10. Auto error rounding function, ultra poor data will be displayed
in orange color and in the lower right corner of the window
11. Issue directly field verification conclusion ( pass or super
poor)
12. Storage capacity up to 1000 items of field test results.
13. RS232 or USB interface to connect computer and print data
certificate.
14. With engineer plastic mold box, shock-proof
