Megger OTS80AF 80kV Auto Portable Oil Test Set
Reliable results with OTS
When performing oil testing the reliability of the results is absolutely essential! The correct diagnosis of oil condition can prevent a catastrophic failure of equipment, and can help maintain operational safety, prevent fires and maintain reliability.
Megger OTS Ensures Reliability
Megger OTS is able to quickly and precisely adjust the electrode gap and this plays a big part with reliability and accuracy. The accurate and smooth gap gauges with black anodised coating are smooth so preventing any wear on the electrode. The coating will also show if the gauge is warn. The electrodes can also be locked into position preventing movement through handling or accidental adjustments.
The Megger OTS also includes a new transformer design which limits the dissipated power within the arc, again improving reliability.
The transformer also detects direct output breakdown detection, in terms of both current and voltage, improving accuracy and also ensuring a high-speed disconnection time. This also offers compliance with both ASTM and IEC requirements.
Low dissipated power and fast breakdown is particularly important for testing silicone oil - Many old oil test sets cannot meet the less than 1 millisecond requirement for silicone oil; the OTS range exceeds this requirement achieving less than 10 microseconds.
The Megger OTS also has optional voltage check meters VCM100D and VCM80D - These ensure confidence in results by verifying output voltage between full calibration.
Finally the units have a built-in automatic temperature measurement with a sensor contacting an area under the vessel with a thin wall for maximum heat transfer.
The measurement is constantly displayed to ensure the sample is at the required temperature before committing to perform a test remember a sample should only be tested once an IEC require that the oil sample be tested at a temperature between 15 and 25 °C. At ASTM between 20 and 30 °C - The temperature needs to be recorded with the test results of course so when it comes to accuracy you really do get reliable results with OTS!

Megger’s automatic laboratory oil test sets perform accurate breakdown voltage tests on mineral, ester and silicon insulating liquids. Moulded test vessels give repeatable results with lock in precision electrode gap setting adjustment wheels. The transparent, shielded lid and large test chamber enable easy access to the test vessel.
What‘s the difference with the OTS AF models?
These 60 kV, 80 kV and 100 kV models have much a larger test chamber for even easier access and cleaning, particularly useful in a lab environment. They are fitted with a 12 key alpha-numeric keypad to facilitate entry of test ID, file names, notes etc. Alpha characters are entered by repetitive pressing on a key. The AF models also have the ability to use a USB barcode reader to scan oil sample barcode labels, ideal for better integration with a LIM system.
