My installation has several buildings that have ungrounded delta 480 volt 3-Phase systems. Has anyone had any experience in converting the ungrounded delta system to a corner grounded? Is it safe to do it? How is the best way to accomplish it?
I have an application for a rechargeable battery. My question is, which is the better technology--the rechargeable Lithium or the Nickel Metal Hydride? Is one or the other preferable for rechargeability? for current density? for discharge voltage characteristics?
Thanks
