Motors etc .
FRAKO POWER CAPACITOR
POWER CAPACITORS ARE SENSITIVE TO :
HARMONICS LIKE 5th,7th,11th,13th etc..
RESONANCE
SWITCHING SURGES
- INRUSH CURRENT
- TRANSIENT RESTRIKING VOLTAGE
- RECLOSING TIME ALLOWING DISCHARGE
OVER VOLTAGE
HIGH PERFORMANCE POWER FACTOR CORRECTION CAPACITORS
Complies to International Standards VDE 0560 Part 46, 47; EN 60831-1 and –2 & IEC 831-1 and –2
CURRENT WITHSTAND CAPABILITY
OVER CURRENT WITHSTAND CAPACITY
TO ACHIEVE LONGER EFFECTIVE LIFE IN A CAPACITOR, ITS OVER-CURRENT WITHSTANDING
CAPABILITY SHOULD BE HIGHER.
FRAKO CAPACITORS
STANDARD CAPACITORS
2 TIMES THE RATED CURRENT PERMANENTLY
1.3 TIMES THE RATED CURRENT PERMANENTLY
350 TIMES THE RATED CURRENT
130 TIMES THE RATED CURRENT
FOR SHORTER DURATION
FOR SHORTER DURATION
THE HIGHER OVER CURRENT WITHSTANDING CAPABILITY BY FRAKO, CAPACITORS ENSURES IT TO
WITHSTAND HIGHER CURRENT FLOW DUE TO : LOW VOLTAGE, OVERLOAD CURRENT, HARMONIC
CURRENT, SURGES, SPIKES ETC.
WHEN THE CURRENT WITHSTANDING CAPABILITY IS HIGHER THE LIFE OF THE CAPACITOR IS LONGER
WITHOUT ANY DERATION.
FRAKO ACHIEVES THIS HIGHER OVERCURRENT WITHSTANDING CAPABILITY THROUGH ITS UNIQUE
COIL DESIGN AND PURITY OF THE MATERIALS BEING USED.
TEMPERATURE WITHSTAND CAPABILITY
TEMPERATURE OF THE CAPACITOR DURING OPERATION ALONG WITH THE VOLTAGE HAS GREATEST
INFLUENCE ON THE LIFE OF THE CAPACITOR. HENCE THE CAPACITOR NEEDS TO WITHSTAND HIGHER
TEMPERATURE :
FRAKO CAPACITORS
- 40 DEG C TO +75 DEG C
STANDARD CAPACITORS
- 25 DEG C
TO
+ 50 DEG C
THIS IS ACHIEVED BY FRAKO DUE TO ITS UNIQUE COIL DESIGN AND THE FORMULA OF THE DRY
MINERAL FILLER.
HIGHER OVER CURRENT & HIGH TEMPERATURE WITHSTANDING CAPABILITIES ENSURE LONGEST LIFE
OF FRAKO, SINCE THE HEAT CREATED BY ATMOSPHERE, LOAD CONDITIONS AND OVER CURRENT ARE
THE DETERIORATORS OF THE INSULATION AND KVAR RATING.
HARMONIC WITHSTAND CAPABILITY
HARMONICS GENERATED BY THE NON-LINEAR LOADS IN THE NETWORK DISTRIBUTION OVERLOADS
THE CAPACITOR LEADING TO VERY HIGH VOLTAGE AND HIGH CIRCULATING CURRENTS
FRAKO CAPACITORS ARE THE ONLY CAPACITOR HAVING SPECIFIC GUARANTEED HARMONIC
WITHSTAND LIMITS :
5th Harmonics
–
5.0%
7th Harmonics
–
4.0%
11th Harmonics
–
3.0%
13th Harmonics
–
2.1%
STANDARD CAPACITORS DO NOT CARRY THIS HARMONIC WITHSTAND CAPABILITY.
SAFETY FEATURES
AUTOMATIC DISCONNECTION OF CAPACITORS BY INTERNAL OVER-PRESSURE
DISCONNECTOR TO AVOID EXPLOSION. THE OIL TYPE CAPACITORS WILL EXPLODE
WITHOUT THESE PRESSURE DISCONNECTORS.
CAPACITORS ARE PROVIDED WITH SPRING LOAD PATENTED TERMINALS WHICH
ENSURES PROPER CONNECTION DURING THE LIFE OF THE CAPACITORS.
THE SPRING ARE DESIGNED TO ACT AS ADDITIONAL INDUCTOR TO SUPPRESS THE
INRUSH CURRENTS.
THE DRY TYPE CONSTRUCTION IN VACCUM SEALED ENCLOSURE ENSURES HIGHER
DIELECTRIC STRENGTH, THEREBY INCREASING THE HUMAN SAFETY.
THE CONNECTION JOINTS ARE WELDED IN ROBOATIC ACTION TO AVOID ANY LOOSE
CONNECTION AND IMPROPER JOINTS.
SALIENT & UNIQUE FEATURES
PATENTED TERMINALS
FRAKO’s Power Capacitor Terminals are patented internationally. These terminals are of spring
loaded type. Internally fixed stainless steel alloy spring ensures tight fitting of the wires and cables
for ever. It avoids the possibility of loose connection of cables at the terminals which creates
sparks and erosion. A regular capacitor terminal with stud and bolted with spring washer loosens
itself over a period due to the expansion and contraction created by the electric heat. FRAKO
Capacitor’s spring also acts as an Inductor to suppress the in-rush current which the capacitor will
experience during switching ON.
DRY MINERAL FILLER
FRAKO Power Capacitors are impregnated with dry mineral filler. The chemical formula of this dry
mineral filler is unique, developed by FRAKO. Due to this special dry mineral filler, the high
temperature withstanding capacity of FRAKO Capacitors from –40C to +75C are achieved.
MANUFACTURING PROCESS
FRAKO has developed a proprietory manufacturing and finishing process for the capacitor coils,
with which it could achieve a high over current withstanding capacity, twice its rated current
permanently and 350 times its rated current for shorter durations. The purity of material being
used, added to the manufacturing and finishing process of the capacitor coils ensures this, prime,
over current withstanding capacity.
