DST-100KV : 100kV เครื่องทดสอบน้ำมันหม้อแปลง, Standard IEC 156, ASTM, มีปริ้นท์เตอร์ในตัว

In all power and distribution transformers, switchgears, load changers, cables and circuit breakers etc., transformer oil or other insulating oils are very important ingredient and used insulation liquid should have a very high dielectric strength. To test the dielectric strength of insulation liquid, we developed DST transformer oil tester (oil dielectric strength tester), which is completely self-contained, compact and portable set. The transformer dielectric oil tester set has been specially designed for testing the dielectric breakdown voltage strength of insulating liquids, a very high voltage is passed through it. The failure of the dielectric strength is shown by a spark across two electrodes. The apparatus to carry out this test is manufactured by us in various voltage ranges and models, as per IEC-156 and ASTM.

Features:

▪ As per specification of standard of IEC 156, ASTM D 877 and ASTM D 1816
▪ Automatic self-test with HV output voltage testing variation of 0-80KV or 0-100KV
▪ Built-in measurement of the temperature of the insulating liquid.
▪ LCD display to rest test results and built-in printer to print out of test results automatically.
▪ Capability of storing100 experimental results, displaying the current temperature. 
▪ At a constant speed controlled by single chip microcomputer.
▪ The Insulating Oil Tester is easy to operate, small size, light weight.
