Abstract
A surge protective device includes an overvoltage protection circuit and a control module coupled to the overvoltage protection circuit that is configured to monitor at least one performance characteristic of the overvoltage protection circuit and is further configured to communicate the at least one performance characteristic to a destination external to the surge protective device.
Claims26
A surge protective device (SPD), comprising:
- an overvoltage protection circuit;
- and
- a control module coupled to the overvoltage protection circuit that is configured to monitor at least one performance characteristic of the overvoltage protection circuit and is further configured to communicate the at least one performance characteristic to a destination external to the surge protective device;
- wherein the at least one performance characteristic of the overvoltage protection circuit comprises an impedance of a galvanic loop formed between one power line of a three-phase power line configuration originating at an electrical power transformer site and a neutral line or a protective earth terminal, the galvanic loop including the control module therein.
An SPD management system, comprising:
- a processor;
- and
- a memory coupled to the processor and comprising computer readable program code embodied in the memory that is executable by the processor to perform operations comprising:
- establishing a communication connection with an SPD, the SPD comprising an overvoltage protection circuit and a control module;
- associating a geolocation with the SPD;
- and
- receiving information corresponding to at least one performance characteristic for the overvoltage protection circuit from the control module.
A surge protective device (SPD) comprising:
- a gas discharge tube (GDT) including an anode and a cathode;
- and
- a current transformer (CT) sensor;
- wherein at least a portion of the CT sensor surrounds the GDT at as location between the anode and the cathode.
A surge protective device (SPD), comprising:
- an overvoltage protection circuit;
- and
- a control module coupled to the overvoltage protection circuit that is configured to monitor at least one performance characteristic of the overvoltage protection circuit and is further configured to analyze the at least one performance characteristic to generate an analyzed output and to communicate the analyzed output to a destination external to the surge protective device;
- wherein the SPD is a first SPD and the destination is a second SPD;
- and
- wherein the control module is further configured to communicate the analyzed output to the second SPD.
