DESCRIPTION:
Dissolved water removal from insulating oil is now possible without the need for heat and vacuum oil processing systems. Specifically developed for dehydrating oil to be used in transformers,patented SD series cartridges can help utilities reduce expenses and increase efficiency when processing oil.
SPECIAL CONSIDERATIONS:
1.SD series cartridges are not designed for particulate removal. Prefiltering through Velcon 1 / 2 micron elements
2.is recommended if particle contamination is suspected.SD series cartridges are not recommended for cost
3.effective removal of free water in insulating oil. If free water is suspected, the oil should be prefiltered using
4.Velcon SD elements.
APPLICATIONS:
SD series cartridges are designed for oil processing situations where dissolved water in insulating oil is a concern, and its removal is desirable. Examples of these situations follow:
• New distribution and EHV transformers are typically oil-filled under vacuum. If the insulating oil has a high total
water content, it is also processed through a heat and vacuum system. SD series cartridges can be used instead of heat and vacuum to dry the oil.
• Repaired transformers are often oil filled under vacuum.
Flowing the oil through SD series cartridges eliminates the need to vacuum process the oil.
• Insulating oil in storage tanks, and tankers of oil that have accumulated a high level of dissolved water can be
recirculated and dried to less than 10 ppm total water using SD series cartridges.
• Use SD series cartridges for processing oil in other high voltage apparatus that is sensitive to dissolved water.
• Use SD series cartridges to help meet processing specifications where dissolved water sensitive dielectric
breakdown voltage test ASTM D-1816 is used,or required.
