3 Selecting the reactive energy compensation system I Reactive energy compensation at low voltage can use one of two systems : fixed system automatic system The choice depends on the following criterion: QC ST 15 % fixed system > 15 % automatic system ST (kva) QC power rating of the H.V./L.V. transformer power rating of the capacitor bank Example 1: QC = 80 kvar ST = 800 kva QC ST = 10 % fixed system Example 2: QC = 160 kvar ST = 800 kva QC ST = 20 % automatic system For more detailed information please consult our GENERAL INFORMATION brochure. 3

4 II Selecting the capacitor type Reactive energy compensation means that the capacitor must be adapted to the intrinsic characteristics of the corresponding mains network (voltage, frequency, cos ϕ, etc.). However, the increasing presence of harmonics in the mains supply means that the capacitor must also be adapted to the degree of interference and the final performance desired by the customer. Depending on the degree of interference or harmonics, four types of capacitor are available: standard type H type SAH type (anti-harmonic reactors) FH type (harmonic filters) Degree of interference SH ST 15 % 15 to 25 % > 25 % standard H SAH FH SH (kva) is the weighted total power of the harmonic generators present at the transformer secondary. ST (kva) is the power rating of the H.V./L.V. transformer 4

6 Fixed system III ALPIVAR general information ALPIVAR : the vacuum technology capacitor DESIGN Alpivar patented capacitors are totally dry units with no impregnation or insulation liquid. They are designed by assembling individual single-phase coils, coupled in a delta arrangement to obtain a three-phase unit. The coils are produced from two films of polypropylene with zinc plating on one side: The metal plating forms the electrode The polypropylene film forms the insulator. All coils are then coated under vacuum into self-extinguishing thermoset polyurethane resin which forms the casing, providing mechanical and electrical protections. ALPES TECHNOLOGIES unique vacuum potting technique ensures that Alpivar capacitors have excellent resistance over time and much longer service life than conventional units. Vacuum potting ensures that no air or humidity remains close to the coils after coating. This design provides excellent resistance to overvoltages and partial discharges. Furthermore, the unit complies fully with environmental protection requirements (no PCB). No insulation or impregnation liquid is used in the Alpivar capacitor. PRESENTATION Monobloc or modular, Alpivar capacitors meet all user requirements. The modular version in particular can be quickly and easily assembled to produce units with various power ratings, enabling integrators and distributors to make significant savings on storage costs. Monobloc INSTALLATION The compact format simplifies installation and significantly reduces or rack costs. The casing is particularly resistant to all solvents and atmospheric agents (rain, sun, salty air, etc.). Alpivar capacitors are thus particularly suitable for installations: outdoors (on poles) in a corrosive atmosphere CONNECTION the terminal blocks are easily accessible on the top of the unit, making Alpivar capacitors particularly easy to connect the use of socket-type terminals enables cable and eye connections to be made directly to the unit s various ranges. Alpivar capacitors are double-insulated or class 2 units, which do not need earthing. Modular 6

7 Fixed system electrical characteristics III INTERNAL PROTECTION self-healing dielectric: this is a result of the characteristics of the metal deposit which forms the electrode and the nature of the insulating support (polypropylene film). This special manufacturing technique avoids blowing the capacitor due to overvoltages. The dielectric is perforated when overvoltage occurs, causing discharges which vaporise the metal around the short circuit and instantaneously restore electrical insulation electrical fuse: one per coil Over prossure disconnecting device: if an electrical fault cannot be overcome by the self-healing dielectric or the electrical fuse, gas is emitted, deforming a membrane and taking the defective coil out of the circuit. These three protection mechanisms, associated with the under vacuum coated coils (technique patented by ALPES TECHNOLOGIES), form a highly advanced unit. DISCHARGE RESISTORS The discharge resistors enable the unit to be discharged in compliance with applicable standards. They are fitted externally on the connection terminals to enable visual inspection. LOSS FACTOR Alpivar capacitors have a loss factor of less than 0,1 x This leads to a total wattage consumption of less than 0.3 W per kvar including the discharge resistors. CAPACITANCE Tolerance on the capacitance value: ± 5% Our manufacturing process, which avoids any air inclusions in the coils, ensures that the capacitance remains exceptionally stable throughout the service life of the Alpivar capacitor.

20 Automatic system VII ALPISTATIC ALPES TECHNOLOGIES, one of the leaders in reactive energy compensation and harmonic filtering, offers a new automatic capacitor bank concept : ALPISTATIC ALPISTATIC is a low voltage real-time reactive power compensation unit using solid state switches. To face increasingly sophisticated industrial processes including large numbers of devices sensitive to voltage variations (PLCs, industrial computers, etc.) or having ultra-fast cycles (robots, welding machines, variable speed drives, etc.), ALPES TECHNOLOGIES developed ALPISTATIC. ALPISTATIC is a soft, fast reactive energy compensation system suitable for this new generation of receiving devices. ALPISTATIC has three main advantages compared with conventional systems using electromechanical switching : no transient currents when capacitors are triggered which might cause voltage troughs. no transient excess voltages or triggering of capacitors due to difficulties in cutting off the electrical arc. very short response time: 40 milliseconds. ALPISTATIC is primarily designed for : compensation for the power factor (cos ϕ) of main low voltage switchboards consumers wishing to reduce their total electricity consumption independent energy generators to optimise units (generator units, etc.). ALPISTATIC is particularly suitable for providing compensation for receivers : which do not accept transient currents or voltage (PLCs, computer equipment,...) with ultra-fast cycles (welding machines, lifts, robots, variable speed drives,...) with pulsating torques (roll mills, compressors, reciprocating saws,...) which generate flicker (devices with extremely inductive loads, arc furnaces, welding machines,...) 20

21 Automatic system main characteristics compared VII SENSITIVE DATA ALPISTATIC CONVENTIONAL Presence of electromechanical contactors No Yes Wear of moving parts No Yes Contact bounce phenomenon No Possible Contact fatigue None High Transient excess currents No Yes (may exceed 200 In) when stages are triggered or released Transient under-voltages None Yes (up to 100%) Compatibility Excellent Average (PLCs, computer equipment, etc.) Compatibility Excellent Poor (welding machines, generators, etc.) Trigger and release response time 40 milliseconds approx. 30 seconds Number of operations Unlimited Limited (electromechanical contactor) Sound level during operation None Low (electromechanical contactor) Reduced flicker Yes (for highly inductive loads) No Creation of harmonics No No 21

22 Automatic system VII Network voltage and current when coupling and uncoupling a capacitor stage Conventional switching using electromechanical contactors Coupling a stage Uncoupling a stage during switching, the following may occur : transient overcurrents exceeding 200 In significant transient over and under-voltages These disturbances may lead to malfunctions on control equipment (PLCs, industrial computers,...). Soft switching using ALPISTATIC solid state contactors Coupling a stage Uncoupling a stage soft switching using Alpistatic solid state contactors prevents network disturbance the reaction speed (40 milliseconds) ensures that power is controlled immediately 22

23 Automatic system VII ALPISTATIC COMPOSITION AND CHARACTERISTICS ALPISTATIC includes: a capacitor bank split into several steps depending on the compensator power rating one three-pole solid state contactor per step (cutting all three phases) fan-cooled heat sink on each solid state contactor one anti-harmonic reactor per step, protecting the solid state contactor and preventing harmonics one set of three HRC fuses per stage a control system for the solid state contactors, including : a reactive energy controller for automatic control - with automatic / manual operation - front panel display showing the number of stages operating - front panel display of cos ϕ. - front panel display of many other electrical parameters (harmonics,...) microprocessor instrumentation and control board using solid state contactors : - triggers and releases contactors within 40 milliseconds - avoids any transient voltages and currents when steps are triggered or released.
