Megger OTS60PB

The Megger range of automatic oil testers offer fully automatic testing with many advanced features. The design allows the operator to simply prepare an oil test vessel, load it with the sample oil, place it in the chamber and initiate the test sequence. The test set then carries out, the series of tests as specified in a large number of oil testing specifications. These define the sequence of tests including the stand and stir times, rate of voltage rise and number of tests resulting in a calculation of the average value of the oil breakdown strength. Withstand or proof testing can
also be selected. This test subjects the oil to a preselected voltage for 1 minute to check for a breakdown.

The OTS60PB is a fully automatic, battery powered, portable oil test set. The test voltage is electronically controlled to the maximum of 60 kV. Designed for on site testing, the instrument is supplied in a rugged carrying case with a handle for ease of transportation. An internal rechargeable battery gives a large number of tests before recharging. A clear display shows a menu of test options and guides the operator through the set up programme, illustrates the correct test electrodes and gap to use, shows the progress of each test and gives the results of the test sequence. The result can be set to give either a numerical average (with standard deviation where specified) or a pass/fail message. The display can be set to read in
English, French, German, Italian, Spanish and Portuguese. An optional printer kit enables hard copies of results to be produced. Accessories, such as the battery charger, spare vessels, spare electrodes and a spacing gauge are located in an attached compartment. Stirring is carried out by a motor driven paddle stirrer. The OTSAF/2 range are laboratory instruments with many
advanced features. Three versions are available with maximum test voltages of 60 kV, 80 kV and 100 kV. They offer fully automatic operation plus the benefit of a built in printer to produce a hard copy of the test results and the ability to program up to five user defined tests for individual applications. The withstand test can be set to operate at any test voltage and with an initial stand time. The dot matrix liquid crystal display can also be set to read in one of six languages. An oil test vessel, configured
to suit the IEC156 test specification, is supplied with the instrument. A large, backlit, liquid crystal display shows test menus, set up screens and results. The resolution of the high voltage output is displayed to 0,1 kV. Results can be printed on the internal dot matrix printer or transferred via the RS232 interface to an external printer or PC. Printouts are automatically time and date stamped. Standard stirring with the OTSAF/2 is achieved by a magnetic stirrer bar. Additional vessels are available optionally, including one suitable for testing to the ASTM D1816 specification. This calls for stirring to be carried out by a motor driven impeller. Each test can be selected with either magnetic stirring, propeller stirring or no stirring. The VCM100 is a calibration meter suitable for verifying the calibration of oil test sets. The meter will enable the
