SPECIAL PURPOSE CAPACITORS

SPECIAL PURPOSE CAPACITORS

These are special type of capacitors made of heavy edge Zn-Al Alloy metallised polypropylene film for handling higher currents and ensuring higher insulation properties, with very low dissipation factor.

These capacitors have an advantage of compact size, easy handling coupled with inbuilt safety mechanism, which disconnects the capacitor in the event of any abnormal conditions like over voltage or over currents.

For CVT
Capacitor is used as a component in the tuned LC circuit of constant voltage power source. These are designed for continuous duty cycle operation or as per the customer’s specific requirements.
The output from capacitors are used in the AC input stage as filters which also gives additional advantage as a power factor correction to the unit. All these capacitors are designed to take care of harmonics upto total of 5% THD (Total Harmonic Distortion). If it exceeds this limit, it would be necessary to use harmonics fillers in order to filter out unwanted frequencies, which can cause heating effect due to high current drawn by the capacitor.

NOTE: Selection of suitable capacitors plays a very crucial role in the life expectancy of the capacitors. Hence it is absolutely necessary to use proper capacitor value with voltage/current rating matching the specific application.

NOTE: Capacitors are housed in aluminum cylindrical can and provided with bottom studs for easy mounting.Capacitors above 10 MFD value can be provided with screw type terminal for handling higher currents and also for better mechanical fitment with cable lugs.

NOTE: Proper selection of the capacitance value will enhance the performance and life expectancy of the capacitor in the tuned circuit.
