Performance Features
◆In power systems, factories, and enterprises, there are a large number of electrical equipment. Their internal insulation is mostly oil-immersed type. The dielectric strength test of insulating oil is a routine test item that must be performed. This instrument is a dedicated device for insulating oil withstand voltage testing.
◆The instrument is available in three specifications: L9801 single oil cup, L9803 three oil cups, and L9806 six oil cups, and is designed with portable and desktop architectures for user selection, 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 voltage rise, hold, voltage drop, stirring, static placement, cup changing, display calculation, and printing, and performs oil circulation withstand voltage tests within the range of 0-80kV.
◆Multiple national standard options: The instrument program includes two national standards, 1986 and 2002, as well as custom settings, to accommodate various user choices.
◆The instrument is equipped with a wide-range watchdog circuit to eliminate the phenomenon of system crashes.

◆The instrument's oil cup is made of composite material 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 in the analog circuit and 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 the grid power as the transformer power supply.
◆The instrument has internal overcurrent, overvoltage, and short-circuit protection functions, and has strong anti-interference capability and good electromagnetic compatibility.
◆Large-screen LCD display, Chinese menu operation interface, panel-type high-speed printer, enabling good human
