YJJ-601 Insulation Oil Tester

General introduction

YJJ-601A (80KV) & YJJ-601B (100KV) is new developed according to the national standard GB507-2002 and IEC60156 (IEC156) Insulating Oil Dielectric Strength Testing Method .LCD screen can display test procedure and test result. All the human interaction operations complete by the rotating mouse .It is very easy for customers to measure the breakdown voltage. It can print the test result.  The instrument is easy to operate and it has beautiful appearance, high measurement accuracy, strong anti-interference ability, it is safe and reliable.



1.The instrument is controlled by large-capacity single-chip microcomputer, and it’s stable and reliable;

2.Built-in wide range of watchdog circuits to avoid the phenomenon of crashes;

3.Various operation options, the instrument program has two national standard methods and custom operation of GB507-1986 and GB507-2002,

4.Oil cup is cast in one time with special glass to prevent the occurrence of interference such as oil leakage;

5.The unique high-voltage sampling design allows the test value to directly enter the A/D converter, avoiding the error caused in the analog circuit and making the measurement result more accurate;

6.The instrument has functions such as overcurrent, overvoltage and short circuit protection, strong anti-interference ability and good electromagnetic compatibility;

7. Portable structure, easy to move, easy to use indoors and outdoors.
