insulation Oil Dielectric Strength
Tester type: CHK-507
Product profile
Standard GB / T 507-2002, DL429.9-91. Used to test the degree of physical contamination of insulating oil by water and other suspended substances by placing the oil in a special equipment, subjected to the action of a uniform AC electric field at a certain speed until the oil is broken down, Can be widely used in petroleum, chemical, metallurgy, electricity, transportation, commodity inspection and scientific research and other departments.
Functional characteristics
- The instrument is controlled by single-chip microcomputer with large capacity, and it works stably and reliably
- The instrument has a wide range of watchdog circuit to eliminate the phenomenon of crash;
- The instrument program has two kinds of national standard methods and custom operation of GB1986 and GB2002, which can adapt to many kinds of choices of different users.
- The oil cup of the instrument adopts the special glass casting once to prevent the occurrence of interference such as oil leakage.
- The unique sampling design of the high voltage end of the instrument allows the test value to enter the A / D converter directly, thus avoiding the error caused by the analog circuit and making the measurement results more accurate.
- The instrument has the functions of overcurrent, overvoltage, short circuit and so on. It also has strong anti-interference ability and good electromagnetic compatibility.
- Portable structure, easy to move, indoor and outdoor use is very convenient.
