Surge Protection Capacitors TRANSQUELL Surge capacitors are designed for protection of rotating electrical machines (large electrical motors generators etc) connected to systems which are subject to voltage and switching surges. The magnitude of lightning and switching surges are often controlled by lightning arresters but this form of protection may not be sufficient to protect the turn to turn insulation of rotating machines from steep fronted voltage waves. It is therefore essential to connect a capacitor between line and earth to modify the rate of rise of the surge voltage ensuring the voltage is more evenly distributed across the insulation of the winding. These capacitors are also used in conjunction with HT Bus Ducts i.e. Segregated Phase / Transformer Generator Interconnection Bus ducts. Manufactured to exacting specifications of customers based on application specific designs these capacitors comply rigidly with international standards IEC specifications and to ISS : 11548 1986.

Steep fronted waves (lightning or switching) on transmission as well as distribution networks, can cause inter turn insulation failure of rotary machines and transformers. Surge Capacitors provide surge protection to high voltage motors, transformers and generators by limiting the voltage rise. Hence Surge Capacitors are used as protective devices for protection of power system equipments. Surge Capacitors are designed taking into consideration its application to operate under severe stringent power system conditions. Connecting surge Capacitors between line and ground at the motor / transformer / generator terminals in shunt, prevent the equipments from damage due to voltage surges. For a more comprehensive protection scheme, Surge Capacitors may be used in conjunction with surge arrester. This surge pack modifies both the wave shape and magnitude.

We are manufacturing and supplying a comprehensive range of capacitors. These power capacitors are used for various applications like, power electronics and electronic circuits.

transquell surge capacitors are designed for protection of rotating electrical machines (large electrical motors generators etc) connected to systems which are subject to voltage and switching surges. The magnitude of lightning and switching surges are often controlled by lightning arresters but this form of protection may not be sufficient to protect the turn to turn insulation of rotating machines from steep fronted voltage waves. It is therefore essential to connect a capacitor between line and earth to modify the rate of rise of the surge voltage ensuring the voltage is more evenly distributed across the insulation of the winding.

In practice, due to limitations in size and cost, rotating machines are not insulated to the same impulse levels as oil insulated apparatus of same voltage class. These machines when connected to system are subjected to surge voltage hazards. The major insulation of any machine is stressed by magnitude of the surge voltage to ground and is protected by a lightning arrester. The minor insulation of any machine is stressed by the rate of rise of Surge voltage, which can be limited by Surge Protection Capacitor.

Agri Boost capacitors from Havells are MPP (metalized polypropylene) capacitors that have been used for PFC applications for more than 7 years. The power range varies from 1.0 to 15.0 KVAr. The Agri Boost capacitor is used for power factor correction. With a compact design, they are the most reliable and manufactured by India's leading electrical goods manufacturers with utmost focus on quality.

Electrical equipments are continuously subjected to abnormal voltage due to internal and external reasons. These may occur on account of lightening, switching operations, system faults and other abnormal conditions. Surge capacitors are capable of bringing down the steepness of over voltage transients that may appear across the transformers, motors and other AC line connected equipments. Unless the transients are swamped effectively, they may cause catastrophic failure of these devices. By reducing the slope of incoming surge, conventional arresters fitted in conjunction with surge capacitors, the level get truncated before operating across the insulation of a device. Surge capacitors are designed to withstand and absorb damped or oscillatory line disturbances without affecting the main frequency performance at the point of common coupling. Surge Capacitors are manufactured as per relevant IEC specifications / IS-11548/1986.

SHARDA surge protection capacitors are of special type capacitors. Its application is of specialized nature i.e. in case of abnormal condition. These capacitors are designed for protection of large rotating machines such as motors generators. At the time of over voltage during electric storms produces surges to electrical equipment s connected to system. The voltage stress between turns of multi turn coil sets a limitation and surge voltage causes breakdown of turn to turn insulation resulting in short circuited turns. The surge capacitors restrict the applied surge to a point remote from the point of connection to the equipment to the system.
