4.10 REACTORS / FILTERS
To improve safety during use of the TPD32-EV series of converters (mains noise, disturbance between drives)
and guarantee compliance with the conditions as required under EN 60146-1-1, IEC 146-1-2 and EN 61136-1,
a three-phase mains choke should be installed upstream of the equipment. In the majority of cases, given a rela
-
tive short-circuit voltage of at least 100 kA and a simultaneity factor of 1 (EN 50178, A 6.3.6), the inclusion of
a switching choke (or transformer) with relative voltage drop of UK = 4% guarantees commutation notches at
the common coupling point (CCP) with an amplitude of less than 20%.
4.10.1 AC input choke
According to EN 61800-3 standard (Table B.1), the max. allowable depth of the commutation notches in the
PC is limited to 20%-40% depending on the installation environment. This may be obtained installing suitable
decoupling reactors or transformers.
On the other hand, for a proper operation, the drive shall be connected to an electrical supply line having a re
-
actance with a relative voltage drop of between 2% (min) and 10% (max). The decoupling reactance requires a
specific calculation based on the relative short-circuit power RSC at the connection point and the actual type of
connection (single or multiple drives, separating transformers, etc.). But, as an indication, the following tables
list the decoupling reactance values Ld (mains spool) having a relative voltage drop of 2% or 4%. The value
refers to a drive rated output current, but can be calculated for the motor DC rated current. The line current value
is given by ILN = IdN x 0.82. (On shown calculations a safety margin of +5% has been added). It should also
be noted that drives having such a high relative voltage usually belong to the "second environment".
The calculation formula is:
Ld = (Ukd *
U

) / (

) or Ld = (Ukd *
