A current sensor is provided for non-invasively measuring electrical current in an electrical conductor. The current sensor includes a housing having a Hall effect device and circuitry for transmitting a signal indicative of the current flowing through the electrical conductor. The current sensor includes a base having a surface for supporting an electrical conductor. A magnetic shielding member is coupled to the surface to shield the Hall effect device from stray or external magnetic fields. A compliant member is coupled to the magnetic shielding member opposite the surface. The compliant member compresses to allow the current sensor to accommodate a large variety of electrical conductor sizes. The compliant member further acts to bias the electrical conductor against the Hall effect device.

Current measuring device

A system for collecting data and monitoring the operation of electrical circuits, such as branch circuits at a substation is provided. The system collects data from a plurality of sensors coupled to a plurality of electrical equipment associated with a circuit. The data from the sensors is collected and used to identify signatures in the data to ascertain potential issues in the electrical protective circuit. The data is further analyzed to determine signatures of abnormal operating conditions. The signatures are compared to reference signatures to identify the abnormal conditions and corrective action is initiated.

Protective relay monitoring system and method of comparing behavior patterns

A system for collecting data and monitoring the operation of electrical circuits, such as branch circuits at a substation is provided. The system collects data from a plurality of sensors coupled to a plurality of electrical equipment associated with a circuit. The data from the sensors is collected and used to determine the activation of the electrical equipment, such as a protective relay for example. The data is further transformed to allow assessment of the circuit's performance against desired parameters.

System for monitoring and assessing electrical circuits and method of operation

A current sensor is provided for non-invasively measuring electrical current in an electrical conductor. The current sensor includes a housing having a Hall effect sensor and circuitry for transmitting a signal indicative of the current flowing through the electrical conductor. The current sensor further includes a clamp that allows an operator to easily and repeatedly install and remove the current sensor from electrical conductors. The current sensor may also include a mu-metal device for shielding the Hall effect sensor for stray magnetic fields generated by adjacent electrical conductors.
