We are Manufacturer, Supplier, Exporter of Surge Capacitors / RC Surge Suppressors, from Pune, Maharashtra, India.
Every electrical installation has power transformers, dry type transformers and HV motors. There is common phenomenon of insulation failure due to switching transients due to vacuum circuit breakers and other switchgears. Multiple switching and re-striking (re-ignitions) of vacuum breakers huge losses are incurred due to insulation failure.
Surge capacitors are used in parallel with HV motors and transformers, eliminates the current chopping, voltage escalation, repetitive pre-ignition and virtual current chopping. Re-striking causing high frequency oscillating current through the breaker will be reduced from hundreds of kHz to few kHz by adding surge capacitor in circuit.
Advantage
Major advantages of Surge capacitor and RC (Resistor and Capacitor series combination) Surge suppressors are,
- Elimination of inter-turn insulation failure
- Extends the life of equipment insulation
- Elimination of multiple re-striking and pre-striking transients associated with vacuum breakers and other switchgears
- Protection of arc furnace transformer due to multiple switching of breakers
Surge capacitors / RC Surge suppressors are designed with latest technology and manufactured in clean environment as per international cleanliness standards. The specialty of our Surge capacitors is low loss, low inductance, high surge current handling capacity, longer life, environment friendly, leakfree termination and highly reliable quality in addition to compliance to international standards. Capacitor dielectric is bi-axially oriented hazy film (BOPP), electrode is pure aluminium foil having purity 99% and above and oil is NPCB (All film or APP dielectric).
When surge capacitors are connected with external non inductive resistor in series with capacitor, it will become a RC or CR surge suppressor. The surge suppressors are to be connected at very close possible distance from the equipment to be protected. Also Surge arrester is used in conjunction with CR surge suppressor to reduce front steepness of impulse which is advantageous to protect HT motor windings.
Applications
We manufacture surge capacitors / RC surge suppressors as per customer's requirements and specifications. Surge capacitors are used for following applications,
- High frequency transient over voltage surge suppression
- Protection of HT motors, transformers, switchgears and generators from steep wave-front, short rise time, high magnitude spikes, surges and other transient voltages due to switching, lightening
- Surface mining (iron ore, copper, coal, other)
- Chemical industry
- Induction and Arc furnace
