IEEE C57.106-2015 pdf free.IEEE Guide for Acceptance and Maintenance of Insulating Mineral Oil in Electrical Equipment.
New mineral insulating oils as supplied must have properties so that new oils meet the standard specification of’ ASTM D3487 and Table I of this guide when received, prior to any processing. When mineral insulating oil specified to conform to ASTM D3487 is rcccivcd. it should be tested to verify conformance with ASTM D3487. Tcsting of the oil for full conformance of all property requirements of ASTM D3487 is only justified under circumstances determined by the purchaser. It is recommended that the purchaser requirc the supplier to provide a certified set of tests for the oil that demonstrate that the oil, as shipped. met or exceeded the property requirements of ASTM D3487. For those circumstances where a full set of tests according to ASTM D3487 are not justified, it is recommended that, at a minimum, the tests shown in Table 1 of this guide be considered. The purchaser of the oil should conduct tests suflicient to satisfy concerns regarding conditions of shipment that might result in nonconformance to ASTM 1)3487 property requirements. Table I lists several of the more important tests with values that should help in the decision regarding acceptance of the new mineral insulating oil.
Insulating liquid is ordinarily shipped in four types of containers: drums, totes, tank trailers, and rail cars. Rail cars are usually under the control of the supplier and dedicated to insulating oil shipment. Highway trailers arc used to transport many different chemical products as well as insulating oil: these trailers are therefore subject to chemical contamination. Special cleaning and drying procedures may be necessary. If problems are encountered, check the history of the shipping containers to sec that they have been cared for properly. It is recommended that the purchaser require the delivery of mineral oil in containers that are properly cleaned to guarantee delivery of oil conforming to ASTM D34X7.IEEE C57.106 pdf free download.
