Ground-Fault Monitoring Method

Patent Number: PH-1-2020-050558

Patent Title: Ground-Fault Monitoring Method

Description

The Ground-Fault Monitoring Method relates to the field of electrical safety and fault monitoring, specifically, to a method of monitoring single-phase ground faults.

​Innovative Features and Benefits:

This technology is a method of monitoring line to ground faults in any establishments characterized by a single-phase electrical wiring system. A ground fault is an unwanted contact between an energized conductor and ground that may result in any danger such as fire, electric shock, or any threats. This Ground-Fault Monitoring Method includes monitoring ground fault in a plurality of parallel branch circuits and having wifi-based technology for real-time monitoring. The existing sensors were installed between the main electrical panel and branch circuit. The purpose of installing the monitoring system in the said location was to include the electrical wiring branch circuit in the monitoring activities. Unlike the existing technology which integrated the monitoring activities in the electrical outlets, the Ground-Fault Monitoring Method offers a better monitoring system by installing the ground-fault monitoring system between the main electrical panel and branch circuit and integrated wifi-based technology to notify the residents of the building whenever a ground fault occurs.

Business Development Opportunity:

The emerging technology of SMART establishments has been prominent in the last years. The Ground-Fault Monitoring Method will provide security in terms of alleviating the problems caused by electrical wiring systems. Aside from the safety that this innovation can extend to any establishment, it can also monitor the status of the electrical system at any period of time. The commercialization of this technology is very promising considering that it will be very useful to any establishments utilizing electricity.

Applications:

This technology aims to provide a method for monitoring single-phase line to ground fault in an establishment, including:

• installing the current sensing devices in each branch circuit between the panel board and the branch circuit;
• connecting each current sensing device to a microcontroller;
• connecting the microcontroller to a transmitter device; and
• configuring a receiver device to receive and display the information from the transmitter device.
