Method and apparatus to generate an alert based on health of an earthing system

An earthing system comprising:

• one or more earth pits that provide a discharge path for a communication system (116);
• wherein the one or more earth pits is positioned inside an earth grid or is located outside and disconnected from the earth grid;
• one or more apparatuses, wherein an apparatus (100) is coupled to an earth pit to generate an alert based on a health of the earth pit, the apparatus comprising:
• a single electrode arrangement comprising:
• a single electrode (102) buried in the earth pit and configured to measure a resistance of the earth pit by one or more sensors at predefined time intervals;
• wherein the one or more sensors (106a-106b) are mounted on the single electrode;
• and
• an electronic module (104) communicatively coupled between the single electrode (102) and the communication system (116), and configured to:
• receive the value of the resistance of the earth pit from the one or more sensors (106a-106b) via one or more communication means;
• compare the value of the resistance with a threshold value;
• communicate the value of the resistance of the earth pit to the communication system (116);
• and
• generate an alert when the value of the resistance of the earth pit exceeds the threshold value, wherein the alert indicates occurrence of an earth fault or a discharge within the earth pit;
• and wherein the single electrode (102) is connected via the one or more communication means to the electronic module (104).

A method (400) for generating an alert based on a health of an earthing system, the method comprising:

• measuring (402), by a single electrode buried in an earth pit, a resistance of an earth pit associated with the earthing system, at predefined time intervals;
• recording (404), by an electronic module, a value of the resistance, wherein the electronic module is communicatively coupled to the single electrode;
• wherein the resistance is indicative of one of a normal working condition and a faulty condition of the earth pit;
• generating (406) the alert, by the electronic module, when the value of the resistance of the earth pit exceeds a threshold value;
• and
• communicating (408), by the electronic module, the value of the resistance of the earth pit and the alert to a communication system.
