Online Earth Resistance Monitoring System a Product is an outcome of inspiration called Make in India, an offering, to fulfill the objective of the program (to facilitate investment, foster innovation, enhance skill development, protect intellectual property and build best in class manufacturing infrastructure in the country thereby helping the economic growth of India by utilizing the existing Indian talent base, creating additional employment opportunities and saving /earning of foreign currency) in every possible aspect by Online Earth Resistance Monitoring System is a State of the Art Device or monitoring the health of your critical Earthing System online which not only monitors the real time earth resistance value & logs data for future data analysis but also raises an alarms, sends messages whenever it detects any failure or deviation beyond set maximum threshold resistance value of the individual earth terminal, grid or of the network. All the information from the site is sent to the server using an advanced safe & secured communication method.
The performance of grounding grid is affected by various factors such as unqualified jointing while building, electromotive force of grounding current, soil erosion and theft of grounding rods. Thus, monitoring and diagnosing the conditions of grounding grid has been an active research field for many years. However, almost all techniques implemented or proposed for grounding monitoring are of “offline” types where special instruments are installed for grounding condition check on a regular or on as-needed basis. These existing methods can generally be categorized into two types: measurement of grounding impedance and detection of grounding integrity.
With the objective to let the user free from all above restraints & to empower him to know the status in real time and log the data for future analysis without any quality comprise, we developed this online resistance monitoring system using a non contact resistance detector. The device measures the ground resistance at a desired resettable interval (1 minutes to 30 minutes) and communicates to the user in login screen in numeric & graphic form, through SMS and allows upper / lower threshold resistance value setting using SMS & SERVER.
The Non-Contact Grounding Resistance Online Detector’s fundamental is measuring return circuit resistance. firstly Sensor sends out a drive pulse signal in to be measured ground return circuit, then measured ground return circuit responses a pulse electromotive force E, under the influence of electromotive force E there will generate current I in the be measured ground return circuit. Sensor measures E and I, and immediately gets resistance of be measured ground return circuit through the formula: R=E/I.
