Best Paper Award at ICE4CT 2022

I have presented my research paper entitled "Neural Network based Transmission Line Fault Classifier and Locator using Sequence Values" at 4th International Conference on Emerging Electrical Energy, Electronics and Computing Technologies 2022. May paper has been selected as one of Best Paper for the conference. 

Successfully Organized the 3rd International Conference on Science, Engineering, and Technology (ICSET2023)

 Alhamdulillah..

We have successfully organized the 3rd International Conference on Science, Engineering, and Technology (ICSET2023) which was held at Raia Hotel, Kuala Terengganu, Terengganu, Malaysia from 22nd to 23rd June 2023. For this conference, I acted as the secretary. The accepted and presented papers will be submitted to AIP Conference Proceedings or Scopus indexed journals. The conference has been conducted in hybrid mode which combine the physical and online presentations. In this conference, I also presented a research paper.

Basic Components Of A Protection System

There are several basic components of a protection system as listed below:

CT (current transformer) 

• Convert the primary current to secondary current and transmit the secondary current to protective relay.

VT (voltage transformer)

• Convert the primary voltage to secondary voltage and transmit the secondary voltage to protective relay.

Protective relay 

• Detect and locate the fault and send a trip signal to the circuit breaker.
• When a fault occurred, the relay will operate by closing the relay contact to complete the trip circuit.

Battery / DC system

• To supply the power for the relay and also to the trip circuit.

Trip coil

• As the trip coil of the circuit breaker energized, the CB operating mechanism actuated and will make the CB to open and isolate the fault. 

Attended PECON 2018

Assalamualaikum.. 

I had presented a paper at IEEE International Conference on Power and Energy (PECON 2018) which was held at Kuala Lumpur from 3-4th December 2018.

My paper titled "Wide-Area Fault Location for Power Transmission Network using Reactance Based Method". Hopefully, I could send a paper for 2019 at the same conference.

Attended ICEESE 2018

Assalamualaikum.. 

I had presented a paper at 4th International Conference on Electrical, Electronics and System Engineering (ICEESE 2018) which was held at Kuala Lumpur from 8-9th November 2018.

My paper titled "Auto-Reclose Relay Simulation for Research & Education". Hopefully, I could send a paper for 2019.

Manuscripts Accepted for Conference

Alhamdulillah.. 

Both of my manuscripts been accepted to be presented at different conferences and both will be published in IEEEXplore database.

Fault Resistance of the Fault Arc

Source: Jianping Wang, ABB, 2013-06-14 KTH

Arc which developed at the transmission line during fault occurrence can be due to an object very near to the line or due to lightning which make the fault current to jump to the transmission tower (earth). This arc representing an equivalent value of fault resistance, Rf. This Rf value is depends on the arc length and fault current. The longer the arc length, the higher the Rf while the higher the fault current the lower the fault resistance as shown by the equation in the figure above. 

The value of Rf can affects the accuracy of fault locating device and also the protection relay which uses the impedance based method (such as distance relay). For impedance based method relay, Rf can affects the accuracy of the relay in determining the tripping signal decision especially for fault near to the setting of zone reach.
