Gangguan pada Gardu Induk Ancol, terjadi karena benang layangan yang mengakibatkan hubung singkat Fasa T terhadap ground SUTT Ancol-Angke. ini malfungsi sistem proteksi GIS Priok Timur bay Ancol . diketahui dengan mengnalisa relai GI dan sehingga besarnya arus gangguan, terpasang yaitu micom P543. Dari hasil perhitungan dapat dilihat gangguan sirkit Ancol- Angke sebesar 92kA juga Timur- 17kA. S...

Directional and non directional overcurrent protection are well established methods of providing either primary or backup protection on distribution networks. Compared to unit protection which only protects a specific piece of equipment, such as a transformer or feeder, overcurrent protection has the advantage of being able to provide protection to large sections of network. To do this the over...

Overload on transformer has been a principal cause of overheating in its windings, reduction efficiency, lowering lifespan and sometimes leads to burn. This can be attributed large quantity current drawn by the loads circumstances. In this paper, design topology capable providing sustainable protection from overload is presented. The designed system detects when being loaded able protect isolat...

Indonesian Navy (TNI AL) is the main component for Maritime Security and Defence. Because of that, TNI AL needs Indonesian Warship (KRI) to covered Maritime area. The main requirement from KRI is fulfilled by demand. To pock of fuel demand from KRI at Naval Base, it needs a new pipeline of fuel distribution network system. The pipeline network system used for maximum lifetime must be protected ...

Differential protection is a popular method to protect aircraft generators against winding faults. Traditional relay-based systems have a limited capability to distinguish between differential current resulting from a winding fault, and the one resulting from measurement noise or current saturation, resulting in false alarms and unnecessary equipment shutdown. Modern aircraft generators are mon...

We demonstrated a 10GHz low phase noise differential Colpitts Voltage-Controlled Oscillator (VCO) utilizing TSMC 0.18 m μ 1P6M CMOS process with transformer coupling technology. The transformer coupling approach not only reduces the phase noise but also improves the power consumption owing to the number of active devices can be reduced. The total power consumption of this VCO is 20 mW and there...

When a transformer is energized the phenomenon of magnetizing inrush current occurs and causes a pseudo tripping signal to the differential relay which leads to the problem of mal operation or false tripping of the relay. In order to avoid this false tripping of the differential relay and for safe operation of the transformer the distinction of inrush current with internal fault current is very...
