Abstract

A portable, handheld unit detects and measures the electrical and magnetic fields radiating from a building, such as a commercial or residential property. The unit senses the phase of the electrical supply to the building and compares the determined phase with a reference phase received over a mobile communications network. The instantaneous phase and the global positioning satellite (GPS) location are accounted for. Direct contact with the electrical supply is not necessary. Access to the building is unnecessary.

Abstract Title: A handheld unit remotely determines the phase of the electricity supply to a property (57) A portable, handheld unit detects and measures the electrical and magnetic fields radiating from a building, such as a commercial or residential property. The unit senses the phase of the electrical supply to the building and compares the determined phase with a reference phase received over a mobile communications network. The instantaneous phase and the global positioning satellite (GPS) location are accounted for. Direct contact with the electrical supply is not necessary. Access to the building is unnecessary.

DESCRIPTION
Phase Identification Unit (PIU) - Ref: 400323
This invention relates to a unit that determines the electrical Phase of a connected electrical supply to a single phase connected property, without entering the property or installing any equipment in a Low Voltage (LV) Substation.
Background
The Electricity Distribution Network Organisations (DNOs) and other organisations/people, require accurate records of the electrical phase of a single phase supply to both residential and commercial properties. Currently the DNOs have either unconfirmed records or no records at all. Equipment already exists that can be used to identify the Phase but these systems require measurements to be made within the properties by the connection of electrical equipment to the electricity meter and compared to measurements made by equipment installed at the LV Substation. The connectivity of equipment within the properties presents the DNOs with a large logistical problem in terms of arranging suitable appointments with the property owners, to gain access to the properties.
Statement of Invention
The use of the PIU eliminates this problem as the determination of the phase is made from outside the property (see Figure 1 - PIU Context), by detecting, measuring and processing the radiated Electric and Magnetic fields emanating from the property.
The measured instantaneous phase is then compared to the instantaneous phase of a system reference that is communicated to the unit over the available mobile communication network.
Both the PIU and the reference are synchronised together through the use of a timing signal received by both the PIU and the system reference.
The PIU can also be used to identify the phase of electrical circuits distributed throughout a property with a three phase electrical supply.
Advantages
1. The PIU makes the phase determination without accessing the property
2. The PIU makes the phase determination without installing equipment within the substation
3. The PIU also provides GPS location information at the point of measurement.
