Method of Assessing Proper Operation of Voltage Control Device

A method of assessing from a location the operation of a first device from among a number of first devices that are electrically connected with an electrical feeder and that are operable to control the voltage on the electrical feeder, the electrical feeder additional having a number of second devices electrically connected therewith which generate varying amounts of electrical power that is contributed at least in part to the electrical feeder, the method comprising:

• detecting at a first time a number of properties of the electrical power at a number of locations on the electrical feeder, the number of properties comprising at least one of a voltage magnitude, a voltage phase angle, a current magnitude, and a current phase angle;
• issuing from the location at a second time subsequent to the first time an instruction to make a change in an operational parameter of the first device;
• detecting at a third time subsequent to the second time another number of properties of the electrical power at a number of locations on the electrical feeder, the another number of properties comprising at least one of a voltage magnitude, a voltage phase angle, a current magnitude, and a current phase angle;
• employing at least a portion of the number of properties and at least a portion of the another number of properties to determine a resultant effect on the electrical feeder between the first and third times;
• determining an expected effect upon the electrical feeder by at least one second device at the third time based at least in part upon a data set that is in existence prior to the third time;
• filtering the expected effect from the resultant effect and determining, based at least in part thereon, a net effect on the electrical feeder of the change in the operational parameter the first device;
• and
• determining, based at least in part upon a comparison between the net effect and a baseline effect for the first device, whether at the third time the first device is functioning properly.
