Portable OLT-series testers are used for determining the dielectric strength of mineral and synthetic insulating oils. Our testers measure the oil breakdown voltage (BDV) in a fully automatic mode and feature a built-in printer for printing out test results. The testers are also equipped with the means of mixing and measuring the temperature of the oil sample, which ensures compliance with the requirements of the majority of the national and international oil testing standards. Proprietary software also allows to create custom user standards with a high degree of flexibility. OLT testers provide high accuracy and stability of the obtained breakdown voltage values, and feature a comprehensive operator protection during high-voltage tests.
To simplify the procedure of calibration and adjustment of the OLT-series oil testers, we have developed a special C-series reference voltage measurement cell with a bright LED display. The cells C-80 and C-100 have an infrared port for wireless connection with a PC, which allows the operator to remain at a safe distance from the high voltage source while using the proprietary KEP Suite software for quick and efficient adjustment of the cell itself.
