Portable OLT-series testers are used for determining the dielectric strength of mineral and synthetic insulating oils. Our testers determine 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 stirring and determining the temperature of the oil sample which ensures compliance with the requirements of the majority of the national and international oil testing standards. Proprietary KEP Suite software 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 are equipped with an infrared port for wireless connection to a PC. This allows an operator to remain at a safe distance from a high voltage source while using the proprietary KEP Suite software aids quick and efficient adjustment of the cell itself.
