Capacitor Bank For Power Factor Correction
Manufacturers and Exporters of Safety transformer like Capacitor Bank (for power-factor correction).
Air Core Reactor
Air core reactors provide a linear/constant response of inductance versus current due the use of non-ferromagnetic material at the core of the reactors. The unique design also helps reduce the losses in the reactors as well as the noise level to help protect any noise sensitive equipments. Estel’s air core reactor can be used in various applications such as current-limiting reactor, harmonic filter reactor, damping reactor or motor starting reactors. Standards- Estel’s air core reactors
Motor Starting Reactor
Motor starting reactor helps limit the inrush current and the starting torque during the starting up of a large 3 phase motor. By doing so, the starting voltage of the motor can also be reduced, making it more efficient. Generally, motors are started with 70 % of voltage and the rest of the voltage, that is normally about 30 %, is dropped across the motor starting reactor. After 15 - 20 seconds, the reactor is switched off by contactors in the system. Standards- Estel’s motor starting react
Line Load Reactor
Line/load reactors play an important role in your power system. It absorbs many of the power line disturbance, which in returns help protect many of your sensitive equipments. Estel’s Line/Load reactors is also a reliable filtering solution which can help reduce the harmonic currents, generated by inverters and drives, in your system. Standards- Estel’s line/load reactors are designed and tested according to IEC60076-6.
Tuned Filter Reactor
Tuned filter reactors are generally used to eliminate specific orders of harmonics, generally the 5th and the 7th order, that are caused by non-linear loads connected to your power system. Eliminating these harmonic currents will help solve issues such as the overheating of transformers and interference in the transmission system. In general, tuned filter reactors are used when the Total Harmonic Distortion (THD) is required to be less than 3%. Standards- Estel’s tuned filter reactors are d
Detuned Filter Reactor
Detuned filter reactors are usually used in series with capacitor banks in order to improve the power factor in your system. The reactors also help to protect your system and capacitor banks from over current during switching on or overloading of capacitor banks due to harmonic resonance. Standards- Estel’s detuned filter reactors are designed and tested according to IEC60076-6.
Potential Transformer PT
Potential transformers are used to measure current and voltage circulating in electrical power systems. They are designed to control circuitry of high voltages by making use of a highly accurate transformation ratio between magnitude and phase. Potential transformers can also be used to step down the system voltage to a safe value which can be fed to low ratings meters and relays. Standards- Estel’s potential transformers are designed and tested according to IEC60044-1, IEC60044-2 or as s
Phase Shifting Transformer
Phase shifting transformer is used to control active power by regulating the voltage phase angle difference between two nodes of the systems, which in returns help improve the AC network efficiency. Not only that Estel’s phase shifting transformers help improve the efficiency, it also ensure reliable and efficient power flow in overloaded transmission line. Standards- Estel’s phase shifting transformers are designed and tested according to IEC60076 or as specified by customers.
Scott V V Transformer
Scott transformer is used to transformed three-phase electric power to two-phase electric power or vice-versa. The purpose of this is to either. 1) give a supply to an existing two phase system from a three phase supply or 2) supply two phase furnace transformer from a three phase source. The Scott transformer also helps to evenly distribute a balanced load between the phases of the source. Standards- Estel’s Scott and V-V transformers are designed and tested according to IEC
Motor Starting Transformer
Motor-starting transformer’s primary function is to limit inrush current and starting torque in AC motors under starting or locked rotor conditions. This eliminates the problems associated with line voltage drop, resulting from high inrush currents. Standards- Estel’s motor-starting transformers are designed and tested according to IEC60076-1 or as specified by customers.
Cast Resin Transformer
Cast-resin transformers mainly consist of core and windings. The winding of this type of transformer is not immersed in insulating oil, but is encased in epoxy resin that helps protect the transformer from dust and corrosive atmospheres. Because no oil is used, cast-resin transformers are generally simpler to install and require no fire-proof vault for indoor installations. Standards- Estel’s cast-resin transformers are designed and tested according to IEC60076 or as specified by custome
