OTS PB and OTS AF insulating oil test sets - Beijing Kanggaote Instruments and Equipment

Product introduction

The OTS PB and OTS AF insulating oil test sets are a range of automatic oil test sets that perform accurate breakdown and withstand voltage tests on mineral, ester, and silicone insulating liquids. All models have precision, shatter-proof test vessels that are easy to clean and provide repeatable results, whether they are used in the field or laboratory. They also have a transparent, shielded lid and a large test chamber, giving you easy access to the test vessel and allowing you see what is happening within the test chamber.

OTS PB models
These 60 kV and 80 kV oil test sets are the smallest and the lightest on the market with weight ranging from 16.8 kg to 20.8 kg depending on the model configuration. These units can be mains powered or battery operated for additional flexibility in portable applications and all PBs are fitted with NiMH batteries and are also supplied with an internal12 V DC charger and vehicle adaptor cable as standard. The transport case and carry bag are optional accessories. The carry bag has pouches for electrode accessory pack, leads, quick user guide, paper roll etc.

OTS AF models
These 60 kV, 80 kV, and 100 kV models have a much larger test chamber for even easier access and cleaning, particularly useful in a lab environment. They are fitted with a 12-key alphanumeric 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 within a laboratory.

▪ Monitoring and maintenance of oil quality is essential in ensuring the reliable operation of oil filled electrical equipment. Codes of practice have been established in many countries that include several different types of test on insulating oils.
▪ One of the fundamental tests of oil quality is the breakdown voltage test, which is a measure of the oil’s ability to withstand electric stress. A low breakdown voltage can indicate the presence of contaminants such as water or conducting particles.
▪ In addition to the breakdown test, the withstand test is a measure of the oils ability to withstand a constant electrical stress. Failure to achieve this also indicates
contaminants.
▪ Care should be taken to ensure the process of sampling oil and subsequent testing does not in any way contaminate it with foreign objects. Cleaning vessels between oil tests should be a rinse with the next sample, never clean with fibrous materials. To ensure an accurate reading set gap carefully and lock adjusting wheels.
