HIGH INRUSH CURRENT WITHSTAD
CAPABILITY IS CRUCIAL |
| |
Capacitors used for power factor correction undergo a lot of switching operations. The high inrush currents that go along with this must be handled without degrading useful life. The pulse strength of this technology comes in particular from the enlarged, sensitive contact area (improved metalspraying). The breakthrough came with a Siemens patent called the wavy cut, plus heavy edge film design. PhaseCap HO capacitors can easily handle inrush currents of up to 200 times rated current. |

|
|
AND WHERE IT IS CRUCIAL
Parallel connection of capacitors.
Non-detuned capacitors.
Capacitor banks using standard contactors.
Restoration after voltage interruptions and brownouts. |

PHASECAP ® HD AC CAPACITORS - [ EXTENDED USEFUL LIFE 130,000 OPERATING HOURS]
After a long drying phase in a high vacuum to eliminate moisture from the active element, the capacitor is impregnated. The case is filled with inert gas and sealed. Then routine test are performed for gas leakage. This production process helps to avoid oxidation and partial discharges (corona effect), promoting capacitance stability over an extremely long period, an essential in filter circuit applications. The Compact Phasecap HD capacitor is a self healing.
Metalized polypropylene film capacitor. The current-carrying metal layer (electrode) is vapour-deposited onto one side of film. |
|
|
|
|
| |
COMPACT DESIGN - LOW HEIGHT, WEIGHT
AND VOLUME
The entire capacitor is composed of three single-phase element stacks. The electrodes are
connected by metal spraying the face ends of the winding elements. The capacitor elements
are delta connected. The winding elements are housed in a cylindrical aluminum case and
hermetically sealed by a press-rolled metal lid. |

|
|
|
|
|
| |
TRIPLE SAFETY SYSTEM
Dry technology: - instead of a liquid impregnating agent, the capacitor is filled with gas. So
there is no risk of fire caused by spurting or leaking oil. Dry design is a must for ecologically
sensitive applications and insurance follow-up.
Self-healing:- the capacitor repairs itself after overload.
Overpressure disconnector: - this prevents the capacitor from bursting at the end of its useful
life or through electrical or thermal overload. |

|
|
|
| |
INNOVATIVE RELIABLE SIGUP-CONNECTION
TECHNOLOGY |
| |
SIGUT terminals ensure reliable and straightforward connection, even in a parallel capacitor circuit, with benefits like Simplified parallel connection of input ends in series.
Protection against electric shock hazard (IP20 to VDE 0106 part 100). Additional connection of discharge resistors for extra reliability and safety. Clamping device to prevent loosening of screws. Cable cross-sections up to 35 mm². |
