The Megger OTS80PB is an automatic portable insulating oil dielectric breakdown voltage test set designed to determine the ability of transformer and other insulating liquids to withstand electrical stress before breakdown occurs. The supplied photograph clearly shows the Megger OTS80PB identification, transparent shielded test chamber, electrode assembly, colour display, navigation keypad, TEST button, and integrated printer section.

The OTS80PB is an 80 kV oil test set intended for both field and laboratory testing. It automatically performs programmed dielectric breakdown tests after the operator places the prepared oil sample into the test vessel and selects the appropriate test standard. Megger states that the OTS PB series is designed for testing mineral, ester, and silicone insulating liquids, with international test standards pre-loaded for automated operation.

The photographed instrument display shows IEC 60156-95 as the selected test standard and indicates Mineral Ester as the displayed oil type. The OTS80PB uses a precision test vessel with adjustable electrodes and a transparent, electrically shielded chamber cover, allowing the operator to observe the test while maintaining the required safety protection.

Applications

The Megger OTS80PB is primarily used for dielectric breakdown testing of transformer insulating oil and other electrical insulating liquids. A breakdown-voltage measurement helps identify contamination such as moisture, dirt, conductive particles, and other impurities that can reduce the insulating performance of an oil sample.

The instrument is suitable for transformer maintenance departments, electrical utilities, transformer manufacturers, service companies, power-generation facilities, laboratories, and field-testing teams. Its portable construction and optional battery operation make it suitable for on-site testing as well as controlled laboratory environments.

Technical Specifications

Megger documentation specifies the OTS80PB as an 80 kV portable oil test set with a 400 mL standard vessel, 150 mL optional vessel, 0.1 kV voltage resolution, ±1% ±2-digit voltage accuracy, 320 × 240 QVGA display, and approximately 520 × 380 × 250 mm dimensions.

Benefits of Refurbished Laboratory Equipment

Purchasing refurbished laboratory and electrical testing equipment can provide utilities, transformer service companies, laboratories, and industrial organizations with access to specialized testing systems at a lower cost than purchasing new equipment. A refurbished Megger OTS80PB can be particularly useful for organizations that need reliable insulating-oil breakdown testing capabilities for transformer maintenance and diagnostic programs.

Refurbished equipment can also be valuable for field-testing operations because the OTS80PB was designed as a portable oil testing system. Depending on the configuration, battery operation, printer, test vessel, electrode set, cables, and carrying accessories may be available separately or included with the instrument.

Additional Information

The supplied photograph clearly identifies the instrument as a Megger OTS80PB. The display shown in the photograph indicates an IEC 60156-95 test sequence and displays oil-type information. The exact installed battery configuration, printer configuration, electrode set, test vessel, and accessories should be confirmed before purchase.

The OTS80PB generates hazardous high voltage during operation. The test chamber incorporates a safety interlock and electrically shielded cover, and Megger documentation specifies safety requirements for operation. Testing should only be performed by appropriately trained personnel following the manufacturer's operating and safety procedures.
