ESTAprop/ESTAdry Power Factor Correction
Capacitors Low Voltage
DW-TYPE FILTER CAPACITORS/IMPREGNATED OR DRY/RESIN-FILLED DESIGN
APPLICATION
ESTAprop DW-type capacitors in rectangular steel casing
have been designed for high current filter circuit applications
in low voltage plants. Loads such as frequency drives,
converters, and other nonlinear loads create harmonics. The
purpose of tuned and detuned filters is the protection of
electrical equipment and reduction of harmonics. DW-type
capacitors have an excellent current-carrying capability and
may be built for high voltages as well as high loads within one
casing.
DW-type capacitors may be used for:
• fixed detuned Power Factor Correction Equipment
• automatic detuned Power Factor Correction Equipment
• tuned filter circuits
DESIGN
The DW-type capacitor is based on MKP-technology. The
active element consists of metallized polypropylene film with
self-healing properties. The current-carrying metal layer is
vaporised onto one side of the polypropylene film. The front
surface of tubular winding elements are joined by means of
the metal spray method (Schooping). A number of elements
will be connected together to get the required capacitance.
The entire winding package will be incorporated within a
welded stainless steel casing.
The casing is fitted with hermetically sealed bushings M12,
for connection of the supply cable.
A threaded stud M10 for grounding is provided. Easy
mounting will be ensured by 4 drillings, Ø 9.8 mm, at the
bottom of the container, or by side-brackets.
This design ensures the highest safety by self-healing
technology as well as by an over pressure monitoring device.
In case of an internal failure, an over pressure may occur and
operate a potential-free contact, which will (connected to a
switching device like a contactor) disconnect the capacitor
from the suppy and thus protect the capacitor from bursting.

The protection of DW-type capacitors is provided by an OVER PRESSURE MONITORING DEVICE, which must be
connected to a contactor or breaker to switch off the unit in case of internal over pressure.
All oil-impregnated part types can also be produced in a PhMKPg dry version. Dimensions and ratings are unchanged.

The total output within one casing may be divided into two outputs and six bushings. Using such an "S"-type terminal arrangement
may be of cost advantage when two outputs are required, but neither of them is large enough to fill up the capacitor casing.
