Reliable 1000A Primary Injection High Current Tester Unit

Product Description

Product Description

In general, field testing and calibration of solid state trip units can be performed by either the primary current injection method or the secondary current injection method. Current injection testing is often associated with high current and high voltage power distribution systems in substations or large industrial installations. By injecting a predetermined current into the circuit breaker, it is possible to determine if the relay will trip at that current, and if so, how long the current needs to flow before tripping is initiated. Primary current injection testing is an invaluable aid in fault finding.

 

Weshine invented Primary Current Injection Test Set (high current generator), which integrates the advantages of similar products at home and abroad, adopts numerical control technology, and has strong anti-interference ability. The self-coupling voltage regulator and the converter made of high permeability iron core have the advantages of large output power, small size and light weight. Mainly used for primary busbar protection and transformation ratio of various current transformers and other testing projects, is widely used in electric power, railway, petrochemical, metallurgy and mining enterprises in scientific research, production and electrical test sites.

TYPICAL APPLICATION
1. Beautiful and elegant PVC panel
2. Directly display the test values of primary current and secondary current, which is convenient for test observation and recording.
3. High measurement accuracy 0.3 class
4. High power, small size, strong load capacity
5. Small size and light weight, the volume is only 30% to 70% of similar products, and it is very convenient to carry.
6. Voltage and current six-and-a-half-digit liquid crystal display, higher display accuracy, more accurate experimental results (the only one in China)
7. 128*64 dot matrix liquid crystal display, the display data is more intuitive and the reading is faster (the only one in China)
8. Instrument display locking function, especially for more accurate and faster readings in transformer ratio experiments (the only one in China)
9. 232 communication function, the experimental results can be uploaded directly or stored in a U disk instead of manual recording (the only one in China)
10. Polarity measurement, automatic measurement of transformer polarity, no need for separate experiments (the only one in China)
11. Added self-locking function (the only one in China)
12. Automatic ratio detection function
