To be useful, the data (oscillography, demand, breaker duty, power quality, etc.) must be retrieved from the HIF detector in the field. With the current lack of standards for substation communications, this is no small problem. The utility must assess the technology available and choose the system that best fits its current and future needs. That system may range from a simple modem for communication with a single HIF detector, to a telephone controller directing calls to various modem connected devices including a HIF detector, or to a Local Area Network (LAN) within the substation tying various devices on different software platforms to a single outside communication port. The utility must acquire and train personnel capable of operating the system and analyzing the data.
