■ Including temperature switches
■ Temperature range up to +60℃
Harmonic filter reactors
Type SKD
Application
Used in conjunction with FASE type Power Factor Correction Capacitors , harmonic filter reactors (blocking reactors) make it possible to install detuned versions of fixed capacitor banks and power factor correction systems. This enables users installing distribution boards to construct customized systems themselves.
power loss
3.5—6W/kvar (depending on version and level of harmonics)
Temperature Range
-10 to +60℃
Design
Low-loss,three-phase assembly complete with mounting brackets,connecting cables and thermal trip.
Ingress Protection
IP00 to IEC 60529 for mounting within an enclosure
Series Resonance Frequency
Version Series Detuning For networks with
Resonance factor utility company AF
Frequency remote control1)
P14 134 Hz p=14% >6Hz
P7 189Hz p=7% >228Hz
Utility company specification with the above must be taken account.
Please refer also to be design notes given in Manual of power
Factor Correction.(other series resonance frequencies on request)
Mounting
The reactor must be mounted in a suitable enclosure ensuring an ambient temperature within the specified range.
Connections
The coil line-side (U1, V1, W1) and load-side (U2, V2,W2) cables can be connected to the switchgear directly or via terminals. The temperature switch (contacts open at 140℃) must be connected to a trip/alarm circuit in Applicable Standards When installing and connecting power capacitors in Germany, the standards VDE 0100 IEC 60364, VDE 0105 IEC 60050, IEC 60529, VDE 0560 part 46 IEC

Important Note
please use only the correct number of the appropriate power capacitors as stated in the table for each individual harmonic filter reactor .If this requirement is not adhered to, the resulting series resonance frequency can under certain circumstances move into a critical range. Apart form possibly overloading the installed components, the utility company's remote control systems could also be adversely affected.
