ZJY Insulating Oil Dielectric Strength (BDV)Tester

ZJY Insulating Oil Dielectric Strength (BDV)Tester

  • category:Breakdown Voltage Tester

  • inquiry
detail

Application:

ZJY automatic oil tester is developed especially for measurement of insulating oil's breakdown voltage, it is unique in the market due to its functionality and the excellent user benefits in comparison to costs.The ZJY oil tester provides delivers clear and reliable measurement results. It is no longer necessary to send samples to the laboratory. Environmental and transport influence on the samples are minimized. Due to its design, the tester is particularly handy, easy to operate and especially excellent to use under tough ambient conditions. By proper programming, ZJY has got functions of auto boosting, step down, stirring, display and print out.


The breakdown voltage test with
ZJY is used to evaluate the degree of impurity in insulating liquids due to foreign particles and water. It meets current regulations and is economically useful to protect electrical systems such as transformers and switches, as well as, medical and security systems from damage and breakdowns. The main reason for such damage is the poor condition of the insulating oil.

Features:

1.Designed as the requirement of international standard IEC156 testing of insulation oil dielectric strength.
2.Fully automatic measurement of the dielectric strength of insulating oil up to 80kv/100kv.
3.Ergonomic operating unit with oil-proof membrane keyboard, easy to read LCD display, and integrated printer.
4.High quality test vessels mcl. transport safety compatible with previous model.
5.High precision of testing and high capacity of anti-jamming,99 groups storage testing data is convenient to reading and print
6.Clear and reliable results through the latest measurement technology.Excellent design for high efficiency and usability

7.Transparent cover on test cup with door and audible buzzer.

8.Test cell is made from transparent high impact glass or acrylic sheet due the flash is observed.
9.Easy to operate, small size, light weight which operated in the open air very conveniently and convenient for maintenance

10.System time can go on running under power off.(the system time just for reference can not be the standard of timing)
