High Voltage Surge Capacitors up to 50 Kv.

Surge capacitors are designed taking into consideration its application to operate under severe stringent system conditions.
Lightning arrestor takes no current from the line during normal operation. When a surge occurs, the arrestor turns on to provide a discharge path. When the surge is gone, the arrestor turns off. The arrestor will handle unlimited amount of current, although amounts exceeding 100 Kilo amps will generally damage the arrestor.
The main advantage of a capacitor is that there is no time delay in turning on as it always conducts. The disadvantage is that the amount of current it can handle is limited to a few amps, depending on the surge voltage. For this reason, an arrestor should always be installed with a capacitor to protect it from intense surges.
Surge capacitors offer the user high transient voltage withstand, long design life, low dielectric loss and rugged construction.
Steep fronted waves (lightning or switching) can cause inter turn insulation failure of rotary machines and transformers. These capacitors provide premium surge protection to high voltage motors, transformers and generators.
Connecting surge capacitors line to ground at the motor terminals prevents this damage. 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.
These capacitors are virtually maintenance free, needing only occasional cleaning of bushings and paint surface and ensuring adequate tightening of electrical connections.
Surge Capacitors are never protected with any type of fuse or any protection as it self is a protective device.
 
Scope
Single Phase capacitors units from 1.1 kV up to maximum 40 kV, 50 or 60 Hz. for indoor or outdoor use.
• with dead casing, open terminal (2 bushings).
• with live casing, open terminal (1 bushing).
The standard microfarad ranges from 0.1 to 0.5
 
Safety Regulations: Quality management system ISO 9001
 
 
Temperature Range
Capacitors are designed for operation between -40°C to +55°C.
 
Dielectric Loss
Dielectric losses in fresh. condition are approx. 0.00005 which reduces after 500 operating hours to a stable state of approx.O.00003.
The dielectric losses, depending on capacitor design, shall be added to losses caused by:
• internal discharge resistors (if fitted).
• internal connections
 
Manufacturing and Quality Control

Imported bi-axially oriented double hazy Polypropylene film and 99.9% pure aluminum foil are used as dielectric and electrode. The wrinkle-free winding of the elements is carried in a Class 100 environment on a Semi-Automatic winding machine with edge and end folding of the aluminum foil. This is to eliminate overvoltage stress at the edges of the buried area of the foil.

Each wound element is tested for DC Overvoltage withstand and adequacy of margins between AI foils and pin holes.
Numbers of elements are interconnected in series-parallel to achieve the desired capacitance and designed voltage rating of the Capacitor.
