Secure Network System Protection Equipment Network of electricity usually comprised of large central plants, network transmission (main and network) and the distribution network. Electric power network consists of many different types of equipment and the physical characteristics and are separated by energy breaker (PMT) as shown in the figure: Technology and Engineering

Secure Network System Figure System network of electric energy Technology and Engineering

Secure Network System Protection system consists of equipment CT, PT, PMT, Power dc / ac, protection relay, the teleprotection that integrated in a series of wiring. Besides, the supporting equipment required for easy operation and evaluation, such as recorder system, the scada system and relay indication (announciator) In one simple example the protection system for network as indicated in Figure below.  Technology and Engineering

Secure Network System Technology and Engineering

Protection System requirement Protection System must need requirement as follows:  - Sensitive when able to feel little interference of any kind. - Reliable when the work will be required (dependability) and will not work when not needed (security). - Selective when capable separate of network that is the subject only - Quick when able to work as soon as possible. Technology and Engineering

Interference of system Interference of system is a interference that occurred in the electric power system (the primary) as the generator, transformer, SUTT, SKTT and others. Interference of system can be as permanent interference and temporary interference.  Technology and Engineering

Permanent interference Interference of system Permanent interference Temporary interference is lost interference by itself when PMT open, such as a strike of lightning that caused a flash over the insulator SUTT. In the circumstances this PMT can immediately re-entered, either manually or automatically with Auto Recloser. Technology and Engineering

Permanent interference Gangguan Sistem Permanent interference Permanent interference is interference does not lost by itself, while repair necessary to the recovery, such as wire SUTT dropouts. Interference of system can be controllable (in the control of O & M) and uncontrollable (outside the control of O & M). Technology and Engineering

Interference of Non System PMT opened is not always due to the occurrence of interference on the system, the PMT can only opened by a relay which working itself or a control cable that injured because of interference and other. Interference such as is not called for interference on the system, hereinafter referred to as non-system interference (secondary side). Type of non-system interference, among others: - damage relay component, - control cable short connected, - interference / induction on control cable. tang cable / knotty Technology and Engineering

Components of Protection Protection system of Electric power generally 1. Current meter component Voltage meter component information obtained from the system, such as currents, voltages between the two. Information obtained from the electric power system will be used to compare with the scale threshold-limit (threshold setting) on the protection equipment. When the scale of the system exceeds the setting threshold-limit protection equipment, the protection system will work to secure conditions. Technology and Engineering

Components of Protection Here's a picture of the systematic from component of electric protection: Technology and Engineering

Electrical Power System Protection Gambar Elemen proteksi sistem tenaga listrik Termination time interruption is the total time needed protection equipment to open it energy breaker also called fault clearing time. Technology and Engineering

Electrical Power System Protection Termination time interruption is one of the most important factors in determining a protection scheme. This is because an equipment protection must be coordinated with the time that other protective equipment so that only the most protective equipment is close to the interference of any work (principle of selectivity). Technology and Engineering

Instrument Transformer a. Current Transformer (CT) / (Trafo Arus) Current Transformer (CT) is a device that functions reduce electricity flows into a large flow with a smaller size. CT is used, because it does not flow measurement may be performed directly on the cash flow burden or interference, this is due to flow is very large and very high voltage. Marked by characteristic CT Current Transformer Ratio (CTR) which is a comparison between the current missed by the primary flow with a miss by the secondary.  Technology and Engineering

Instrument Transformer b. Potential Transformer (Trafo Tegangan) Potential Transformer is electrical equipment a function of lowering the high voltage into a lower voltage in accordance with the relay setting. Transformer also has a number comparison coil / voltage primary and secondary indicates that class.  Technology and Engineering

Relay / Rele Relay / Rele come from telegraph technique, in which a coil-energize by weak currents, and this interesting armature coil to close contacts. Relay is the heart from the Electrical Power system protection, and has developed into a complex equipment. Relay divided into two groups: Technology and Engineering

Comparator: Rele / Relay Detect and measure abnormal condition, and open / close contact (trip). Technology and Engineering

Auxiliary relays: Rele / Relay Designed for use in the Auxiliary circuit controlled by the rele komparator, and open / close contacts another (which generally have current strong) Technology and Engineering

Circuit Breaker (CB) Circuit Breaker (CB) is one of the power breaker equipment useful and decide to connect a series of conditions in the electric load is connected to directly and securely, both in normal conditions and when there is interference. Based on media electrical breaker / fire extinguisher interest, there are four types of CB as follows:  1. Air Circuit Breaker (ACB), using media such as air. 2. Vacuum Circuit Breaker (VCB), using media such as vacuum. 3. Gas Circuit Breaker (GCB), using media such as gas SF6. 4. Oil Circuit Breaker (OCB), using media such as oil. Technology and Engineering

DC System Power Supply DC System Power Supply is a power supply reserve that consists of a Battery Charger, as the equipment that change AC to DC voltage, and Battery, as a reserve power storage. As equipment protection, DC Power Supply System is the equipment which is vital because if an interruption occurs and the contact has been connected, the DC Power Supply System will work cause to open the CB. Charger is the main source of DC power supply, because the charger is a tool to change the AC power into DC power (rectifier).  Technology and Engineering
