Dr. Dalal specializes in condition assessment techniques for electrical equipment. In his Doctorate’s work at Arizona State University, he performed extensive research on identifying and quantifying degradation parameters of underground XLPE insulated distribution cables. This resulted in development of a new accelerating procedure for underground XLPE insulated cables for specific atmospheric conditions and an aging model, which uses feedback from actual field experience to gauge the future performance of the underground distribution cables.
At Exponent Dr. Dalal has performed safety evaluation of Li-ion rechargeable battery packs on handheld and notebook computers, portable audio devices, and other portable systems. Dr. Dalal has also investigated safety and reliability of computer power supply.
Prior to joining Arizona State University, Dr. Dalal worked as a Design Executive with L&T-Sargent & Lundy Ltd., where he performed engineering calculations using relevant IEEE standards. Dr. Dalal designed and successfully implemented a complete synchronization scheme for a power plant. He has also developed schematics for control and relay panels for unique remote synchronizing functions.
