LV Capacitor Banks MSC Series LV Capacitor SCS Series Capacitor Banks with Harmonic Filter Product Code (MSC xxxx) Nominal Power (kvar) Nominal Voltage (V) Dimension (mm) MSC 8.33k-48 8,33 480 340 x 70 x 220 MSC 16.66k-48 16,66 480 340 x 70 x 220 MSC 33.3k-48 33,3 480 340 x 70 x 220 MSC 33.3k-96 33,3 960 340 x 70 x 220 MSC Series Low Voltage Power Capacitors consist of metallized polypropylene film bobbins which are placed in metal casing with different connection techniques such as series and parallel. MCS capacitors have high mechanical and electrical resistance thanks to the metallized polypropylene film and the elements production technique which uses thermosetting resin and occurs in a vacuumed and dry environment. Bobbins are also coated with resin in a vacuumed and dry environment; resin inhibits air and humidity during expansion or sweating. Elements consist of series and parallel groups in casing. MSC Series Power Capacitors are manufactured according to thermal, electrical and mechanical parameters and their designs are produced according to the thermal cooling due to the element temperature change in casing. The elements metal box is filled with inorganic and fire proof granules which do not prevent thermal cooling and extinguish flames in case of possible defect. The production of MSC capacitors doesn t use any harmful gas and materials and is in accordance with international standards and requirements which enables the capacitors to be recyclable at the end of their lifetime. External discharge resistors are used as standard in MSC capacitors and provide voltage reduction between the capacitor terminals when power failure occurs. MSC capacitors have perfect current and voltage withstands which extends their lifecycle. They can be used in all kind of compensation and filtering applications with high performance and safety. They have been known for their stability and high capacity for many years thanks to the high quality metallized self-healing polypropylene film and internal fuse. Thanks to their low dielectric losses, the MSC capacitors provide compensation and filter needs of facilities and they keep active power losses at minimum levels. Basic features of SCS Series compensation systems are: Capacitors are switched on and off with static switching which contains thyristor diode packets instead of contactors. During switching (ON/OFF) there are no transient situations such as over current and voltage transient. Thanks to the millisecond response time in low voltage, real time reactive power compensation can take place. The system contains harmonic filter reactors which enable it to work without any effect of the harmonic loadings and inrush. Any potential serial and parallel resonance can be eliminated through harmonic filtering. The system can be used at 50Hz and 60Hz across all kind of facilities and processes. The power factor is continuously kept at level 1 which delivers excellent results. They provide long life with physical strength and withstand values of 20% over voltage and 50% over current. The compensation system is manufactured and tested in accordance with IEC standards. These systems are economic and practical because they offer easy installation, manpower and time saving, no additional material, high level protection against touching, electrical and physical strength. They also provide increase of power and revision. Basic structure of SCS Series compensation system consists of C7s type modular compensation rack units which have state switch and harmonic filter. The modular compensation units are mounted consecutively and confirm either in racks or a withdrawable form. Using the modular rack format allows the operator to add and modify the steps in case the facility becomes bigger or smaller during the process and requires step changes; that was the power increase can be completed easily and is not delayed with the operation capacity change. Wire Connections Metal Enclosure Discharge Resistor Power Cables Capacitor Banks with Contactor 30-60 seconds delay due to the capacitor s discharge. Capacitor Banks with Thyristor 20-40 ms delay without discharge waiting time. Suitable for power required in real time compensation. In-house Metallized Polypropylene Film Plastic Case Fuse Link Thermo-Setting Resin Distortion of Over Current and Transient Voltage Noise Level Inrush current and transient voltage distortion can occur during switching. During mechanical switching, noise can occasionally occur due to arcs and over current. Number of Switching Limited Unlimited No risk of inrush current and transient voltage distortion due to the system soft and impulse-free structure. This system works without mechanical switching which ensures a noise-free and continuous operation of the capacitor steps. Capacitor Element Inert & Non-Toxic Granules Holes For Fixation Application Areas Facilities with low and slow load changes due to the total loading. Facilities with rapidly varying load as well as facilities which require fast compensation systems. 6 7

HV Capacitor Banks Our enclosed capacitor banks are used for power factor correction, voltage balance, harmonics suppression and are specifically designed to maximise network capacity in industrial applications and electrical distribution networks. Types of Banks 1.Fixed Capacitor Banks These banks are connected in continuous mode directly to the loads and provide a fixed quantity of reactive power at all times. They can be permanently connected to the loads or can be switched by means of devices located in customer s switchgear. 2.Fixed Capacitor Banks with Switching Device These banks are similar to the previous type but in addition, they are fitted with a switching device (contactor or circuit breaker), that allows them to be connected and disconnected from the network at any time. 3.Automatic Capacitor Banks These banks consist of different steps each of which is composed of capacitor units, reactors and switching devices, all mounted in a common enclosure. They can improve the power factor by providing the required amount of reactive power under varying load conditions. In addition, The operation, control and monitoring of the different steps are carried out by a microprocessor based controller based on the need for reactive power. Product Features Modular, compact and robust design optimized for future expansion of the system and for easy transport, storage and installation. Galvanized steel enclosure available for indoor and outdoor installation with different ventilations systems. Protection class ranges from IP30 to IP54. Design and testing compliance with the requirements of the latest edition of relevant standards and the specific technical requirements set by the customers. Use of simplified design and proven components ensures high reliability and low maintenance costs. Optimised to give a low environmental load by using recyclable materials. The banks are supplied as fully assembled units, factory tested and ready for connection Banks Configuration Capacitor Banks are usually formed by an incoming cubicle where the main circuit breaker, earthing switch and control and protection relays are placed. There are one or more step cubicles where capacitors, reactors, fuses and switching devices are located. Banks can be manufactured with various options and configurations to meet virtually all customer needs. Protection Devices for Typical Systems Capacitor units Internal or HV-HRC fuses Discharging resistors or quick discharge transformers. Unbalance current protection Over-current and earth-fault protection Over and under-voltage protection Internal temperature protection Earthing switches and protection locks Switching Devices Vacuum or SF6 contactors and circuit breakers. Reactors Capacitor Banks can be applied with air core or iron core damping or de-tuned (low pass) filter reactors, depending on the harmonic level of the network and the number of steps needed.
