Overview
The L9803 insulation oil dielectric strength tester (three cups) adopts a large capacity microcontroller and dual CPU control for stable and reliable operation. Built in function generator, with minimal distortion of the power frequency sine wave and stable frequency, avoiding the impact of power grid harmonics on test results when directly using the power grid as a booster power supply
Product Details
L9803 Insulation Oil Dielectric Strength Tester (Three Cups)
Overview
Designed and manufactured according to GB/T5564-2007 "Measurement of relative permittivity, dielectric loss factor, and DC resistivity of liquid insulation materials". Used for measuring the dielectric loss factor and DC resistivity of liquid insulation media such as insulating oil. Integrated structure. Internally integrated with main components such as dielectric loss oil cup, temperature controller, temperature sensor, dielectric loss testing bridge, AC test power supply, standard capacitor, high resistance meter, DC high voltage source, etc.
1、 Instrument features:
1. The instrument adopts a large capacity microcontroller and dual CPU control for stable and reliable operation.
2. The instrument is equipped with a wide range watchdog circuit to prevent system crashes.
3. Multiple national standards selection, the instrument program has two national standards of 1986 and 2002 and custom settings, which can adapt to various choices of different users.

Product Usage and Characteristics
The stirring is automatic magnetic stirring, eliminating the unsafe factors of manual stirring; The number of runs, mixing and settling time can be changed at any time; After the oil sample is punctured, there will be an audio alert, and the audio arrangement has a certain regularity. By listening, you can also know how many times it has been run. If you do not need the audio alert, you can turn it off; The voltage regulation system adopts a variable speed mode, with slow boost and fast return to zero; Diversified operating modes; The perpetual calendar displays the time; Long term storage of measurement data. Suitable for testing the dielectric strength of various insulating oils. Its main performance features are: equipped with automatic detection function, such as automatically entering the reset state and executing the regulator to return to zero when turned on. Adopting a miniature TPU-A panel printer for automatic printing output. According to user needs, the number of tests, stirring, settling time, and sound and light control reminders can be changed for continuous printing and non printing. This instrument adopts fully automatic magnetic oscillator stirring to eliminate unevenness and bubbles in the oil sample.
