YH-507B automatic insulation oil dielectric strength tester

Instrument features

The instrument adopts large capacity single chip microcomputer control, stable and reliable operation;

The instrument has a wide range watchdog circuit to eliminate the phenomenon of crash;

A variety of operation options, the instrument program has GB507-1986, GB507-2002 two national standard methods, industry standard DL/429, international standard IEC156 and custom operation, can adapt to a variety of users' choices;

The instrument oil cup is cast in one piece of special glass, which eliminates the occurrence of interference such as oil leakage;

The unique high voltage sampling design of the instrument allows the test value to directly enter the A/D converter, avoiding the error caused in the analog circuit, so that the measurement results are more accurate;

The instrument has overcurrent, overvoltage, short circuit and other protection functions, and has a strong anti-interference ability, good electromagnetic compatibility;

Portable structure, easy to move, indoor and outdoor use is very convenient.
