Performance Features
◆In power systems, factories, mines, and enterprises, there are a large number of electrical equipment. Their internal insulation is mostly oil-immersed insulation. The dielectric strength test of insulating oil is a routine test item 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 microcontroller with dual CPU control, which can automatically complete a series of operations such as boosting, holding, reducing voltage, stirring, static settling, cup changing, display calculation, printing, etc., and performs oil circulation withstand voltage tests within the range of 0-80kV.
◆Multiple national standard selections: The instrument program is equipped with two national standards, 1986 and 2002, as well as custom settings, to adapt to various user choices.
◆The instrument has a built-in wide-range watchdog circuit to eliminate the phenomenon of system crashes.

◆The instrument's oil cup is made of composite material and cast in one piece, eliminating oil leakage and fragility.
◆The instrument's 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: The power frequency sine wave has low distortion and stable frequency, avoiding the influence of grid harmonics on test results when directly using the grid power as the booster power supply.
◆The instrument has built-in overcurrent, overvoltage, short-circuit protection functions, and has strong anti-interference ability and good electromagnetic compatibility.
◆Large-screen LCD display, Chinese menu operation interface, panel-type high-speed printer, enabling good human-
