For an electrical system a sensor and associated circuits are provided for on-line monitoring of the state of the high-voltage insulation in the electrical system. In this arrangement, both the power frequency signal and of the radio frequency signals associated with partial discharge activity may be monitored and transmitted from the sensor to remote monitoring instrumentation. The sensor is disposed in a stand-off insulator which also may act to support the high voltage conductor system.

A normally ungrounded power system for a oil well is provided which includes a power transformer above ground and a pump motor below ground. There is provided a signal system which includes a below ground sensor system and an above ground signal conditioning and monitoring unit where the sensor system utilizes the main power lines for carrying the sensor signals. A connectable high resistance grounding scheme is provided to the aforementioned floating system, so that in the event of a arcing ground fault or similar occurrence the system may be immediately grounded, thus compensating for the effects of the arcing ground fault and providing personnel safety and electrical equipment protection. When the high resistance grounding system is not utilized the aforementioned signals from the sensors are easily carried by the power conductors.

A network system includes a network bus structured to power plural network loads. A generator is structured to provide forward power flow to the network bus. A generator protector relay cooperates with the generator. Plural network protectors correspond to plural power source feeders, which are structured to provide forward power flow through corresponding network protectors to the network bus. Each network protector includes a network protector relay having an interface communicating power flow information to a communication network. A controller cooperates with the generator protector relay and includes an interface receiving the power flow information from the communication network and a processor determining whether there is forward power flow through the network protectors to the network bus. The processor enables the generator protector relay responsive to the forward power flow and reduces output from the generator responsive to the forward power flow being less than a predetermined amount.
