Introduction
Construction of surge arrester
Lighting Arrester consists of two arc gaps and a non-linear register in terms of structural demonstration.Lighting arresters are kept with one end load and the other end earthing.
What is Lighting Arrester Non Linear Resistance is usually temperature dependent.That is, when the temperature rises, the resistance decreases and when the temperature decreases, the resistance increases.
When there is a surge on the line, the temperature in the line increases and the resistance of the non-linear resistance of the lighting arrester decreases.Utilizing this property of non-linear resistance, the lighting arrester can bring the surge into itself and ground it.
Other normal times when the voltage is limited with line voltage the line temperature is low . It means surge arrester only works when surge comes in line.
Surge can come in line all the time. This surge arrester is kept in regular maintenance to protect other devices from damage.
But sometimes surge arresters can damage other devices on the surge line due to lack of maintenance for some reason. The surge arrester diagnose device is used for this maintenance problem and Protect other device from surge.
Surge arrester also use as a diagnose device continuous monitoring and recording the data amount of surge comes in line and predicting the surge arrester damage internal part automatically alert to operator for maintenance.
Let's talk a little more about this device.
Advanced Automation of surge arrester
Now a day surge arrester is used for diagnostic systems and is performed automatically by the Internet of Things(IOT). Device Internet of Things (IOT) monitors the data from surge arresters.
It can detect surge temperature, line voltage , leakage current , humidity and predict the data if any abnormality in surge arrester then send an alert signal through IOT network to the control room.
Control room informs the maintenance team. Speciality of IOT based diagnostic device for surge arrester is the whole system does not need any external power supply and signal send are received via wireless connectivity.
If any abnormality in this diagnostic device for surge arrester this signal is also reported to the operator. Which makes this device much more reliable.
This device is highly used in air insulated substation and gas insulated substation.
Other important features are that the system is able to record past data , enables wireless connectivity across a wide area, easy to install and send data and receive secure network protocol.
This device is capable of calculating the lifeline of a surge arrester.This type of device is capable of communicating with the substation automatically. And timely maintenance saves a lot of damage as a result with real time analysis.
Conclusion
Economically this device is efficient and also quite efficient in terms of operation. In the future, such devices could give a new direction to the electrical system.
