Performance Features
◆In power systems, factories, mines, and enterprises, there are a large number of electrical equipment. Their internal insulation is mostly oil-filled insulation. The dielectric strength test of insulating oil is a routine test that must be performed. This instrument is a special instrument for insulating oil withstand voltage testing.
◆The instrument has three specifications: L9801 single oil cup, L9803 three oil cups, and L9806 six oil cups, and is designed with portable and desktop architectures for users to choose, suitable for both indoor and outdoor use.
◆Internally, it adopts a large-capacity single-chip microcomputer with dual CPU control, which can automatically complete a series of operations such as boosting, holding, reducing voltage, stirring, static placement, cup changing, display calculation, printing, etc., and performs oil circulation withstand voltage tests in the range of 0-80kV.
◆Multiple national standard selections: The instrument program is equipped with two national standards, 1986 and 2002, and custom settings, which can adapt to various choices of different users.
◆The instrument is equipped with a wide-range watchdog circuit to eliminate the phenomenon of system crash.

◆The oil cup of the instrument is made of composite material by one-time pouring, eliminating the phenomena of oil leakage and fragility.
◆The unique high-voltage end sampling design allows the test value to directly enter the A/D converter, avoiding errors caused in analog circuits, making the measurement results more accurate.
◆Built-in function generator, with small distortion of power frequency sine wave and stable frequency, avoiding the influence of grid harmonics on test results when directly using grid power as the booster power supply.
◆The instrument has overcurrent, overvoltage, short-circuit protection and other functions, and has strong anti-interference ability and good electromagnetic compatibility.
◆Large-screen LCD display, Chinese menu operation interface, panel-type high-speed printer,
