This paper accomplished a system of high-rise building’s fire monitoring system based on CAN bus. It is applied in avoiding the harm of leakage current , over current and short circuit, and protecting electric power distribution circuits and electrical equipment, thus to prevent the occurrence of electrical fire. The monitoring system can detect phase current signal and the leakage current signal, and can display real-time and alarm. It also can proceed network service and complete the distributed remote control and fault diagnosis. Practice shows that the system the characteristics of high precision, safe and reliable, low rate of false positives, easy operation and maintenance, etc .It can satisfy the demand of large high-rise building electrical fire.

In the smart power grids construction and for the needs of the power distribution reliability，and for the overhaul and maintenance of the power equipment, it is important for all the operation equipment condition being under monitoring. All equipment has its own characteristics. These characteristics give the customizing messages for monitoring the equipment condition. For the overhead lines insulators, its leakage current mainly mirror insulating property and can give out the insulating strength degrading in time. So trying to monitor the insulators leakage current is significant for Electrical safety. In this paper, the polluted insulator leakage current generating mechanism and characteristics in the operating voltage be analyzed, the actual use of the leakage current on-line monitoring methods and equipment be compared. Based on MSP430 single chip, one facility insulator leakage current online monitoring device is developed. This on-line monitoring device make up of leakage current signal acquisition unit, periodically the leakage current signal into the signal processing unit, the microcontroller to process data effectively, and given the alarm in case of problems, and the data stored by the host computer communication module and communication. By preliminary testing on the good and polluted insulator, the test data reflect the polluted insulator leakage current changed condition, and can find out fault insulators nicely.

Short circuit causing over current problem and can might causing interference of the equipment performance such as distribution transformers also causing widespread disruption occurred. In resolving such interference is required as protection system on the distribution system. Seeing all above is needed coordination between the supporting component of the protection system which is consisted of Over Current Relay (OCR) and Ground Fault Relay (GFR). The research was conducted at PT. PLN (Persero) South Bali Area Network, INDONESIA on recloser in the feeder line of Penebel. OCR setting between the Relay feeder of Penebel, Recloser Celagi, Recloser Bakisan, and Recloser Benana still less selective, with time value coordination between average security was still less than 0,2 second. Then OCR setting and GFR relay feeder of Penebel, Recloser Celagi, Recloser Bakisan, and Recloser Benana was recommended for re-setting in order to minimize disruption and electric power distribution system to be reliable.

Distance Setting

The substation is one of the components in the electric power distribution system which plays a very important role because it is the connection between electricity services to customers. In the electric power distribution system, there are disturbances that often occur, one of which is a short circuit. For that, the way to overcome this is using the Distance Relay protection system, OCR / GFR and DEF. The purpose of writing this research is to determine the value of setting relay distance, setting Over Current Rele and Directional Earth Fault relay in order to secure the 70 kV transmission network connected to GI Banaran, which is then simulated using DigSILENT 15.1 software on the Pare line by calculating symmetrical and asymmetrical disturbances. including 3-phase disturbance on February 1, 2018. The simulation results show that the 3-phase disturbance occurs at Zone 1 relay distance of the Banaran Bay Pare substation with a trip time of 0.02 seconds with a fault impedance of 0.083 ohms below the relay impedance value of 0.887 ohms. The coordination between the distance relay on the side of the Banaran Bay Pare substation has worked well because there is no error reading the relay when it will cut off the disturbance.
