    The grounding of AC and DC drive systems should detect and clear ground faults both on the source and load side of the converters. Most drive systems are separately derived through a stepdown transformer, which serves as a drive isolation as well as rectifier transformer. Isolation transformers on individual or group drive systems, downstream of main substation transformers are also common. An out... View full abstract»

    Most organizations have been, or will soon be, affected by downsizing. The 1995 AMA Survey of 1003 organizations reported that one in four organizations have plans to eliminate jobs before the end of 1996 (the highest future index in the survey's 8-year history). This survey also compares the leading reasons given for downsizing. This paper presents recommendations for the management of the person... View full abstract»
