Abstract
The operation of a geothermal well power-generationsystem is monitored by sensor, communication, and performance monitoring equipment normally associated integrally with the operating power generation system. Sensors detect magnitudes of well water temperature, of water pressure below and above the pump, and of other parameters of interest deep in the well. This data is transmitted by multiplex communication via a novel two-wire line telemetric system to receiver and utilization means at the earth's surface. Power for excitation of deep well monitor units is supplied from the earth's surface also by the two-wire telemetric system. A configuration involving a mechanically separable transformer disposed serially within the two-wire line aids installation of the monitor system and its removal in the rare event that it is required to remove the entire pump from its operating deep well site.
