ESTAprop/ESTAdry Power Factor Correction
Capacitors Low Voltage
CAPACITORS IN RECTANGULAR STEEL CASING
APPLICATION
ESTAprop PhMKP-type capacitors in rectangular steel
casing have been designed for Power Factor Correction in
low voltage plants. Loads as motors and transformers
consume real power as well as reactive power. Generators,
supply cables, and other electrical distribution equipment
should be relieved from reactive power.
ESTAprop capacitors may be used for:
• areas with dust and moisture, which require a high degree
of protection
• free standing, fixed individual-PFC (e.g. motors, lighting,
transformers)
• free standing, fixed central-PFC (e.g. group of loads)
• harmonic trap (e.g. UPS, frequency drives, converter)
DESIGN
The ESTAprop MKP capacitor in steel casing consists of a
number of three-phase tubular can type capacitors (see
PhMKP... Cylindrical Aluminum). The individual aluminum
cans are wired together and mounted onto a steel frame. The
steel frame together with the cans is housed in a common
sheet steel casing. The supply cable may be connected at
three or six threaded studs, on top of the capacitor. A
threaded stud M10 for grounding is available. Easy mounting
will be ensured by 4 drillings, at the bottom of the container.
This design ensures highest safety by:
• self healing technology
• over pressure tear-off fuse
• robust steel container
• massive connection studs
