Automatic Oil Dielectric Tester is designed to assess the dielectric strength of insulating oils. The oil tester is fully automated and utilizes industrial Single-Chip Microcontroller (SCM) technology for precise control and seamless integration with its circuitry. With a capacity of 2.0 KVA, it can store up to 99 records of oil samples for later review and printing and provides valuable information about the quality and condition of the oil. It is essential for quality control in the production of insulating oils and for regular maintenance and condition assessment of high-voltage electrical equipment. They are used in industries such as power generation, transmission, and distribution, as well as in transformer manufacturing.
