Dynamic Power Factor Correction
Thyristor Module TSM-AT
General:
Conventional systems for power factor correction are used to optimize the power factor and
reduce the level of harmonics in the net. The usage of new technologies in modern industry has
negative impacts on electrical power quality of the main supply networks, eg. frequent high load
fluctuations and harmonic oscillation. Excessive currents, increased losses and flickering will not
only influence the supply capacity but will also have a significant impact on the operation of
sensitive electronic devices. The solution for this are dynamic power factor correction systems.
With the TSM-AT module we provide the main component – „electronic switch“ – for dynamic
power factor correction. The TSM-AT is a fast electronically controlled, self-observing
thyristor
switch for capacitive loads up to 100 kVAr, which is capable to switch PFC capacitors within a few
milliseconds as often as required.
Features:
-
Real 3-phase switching
(usage only with single-phase capacitors
L-N)
-
Output up to 120 kVAr at 690 V
-
Usage for PFC-systems with and without
reactors (programmable)
-
Connected load (output) programmable
-
Easy programming for the individual
application
via
multi-lingual
plain
language display
-
Indication of all relevant parameters of
the grid
(voltage, current, temperature...)
-
Alarm output and error message storage
