THREE-TERMINAL TEST CELLThe test cell YAPI-3 is used in the automatic tester TANGENT-3M for measuring dielectric dissipation factor (tan δ) of insulating oil.
YAPI-3 fully complies with the requirements of the international standard IEC 60247 with regards to three-terminal test cells for precision measurement of insulating oil dissipation factor.
All body components of the cell are made to high precision and smoothly polished for ease of cleaning.
The error in reproducing the electrical capacity of YAPI-3 after disassembly-assembly does not exceed 3%.
The cell electrodes are made of high-quality corrosion-resistant stainless steel.
The electrodes are reliably isolated from the external environment with an insulating disk made of low porosity PTFE.
