Elimination of UPS harmonic disturbances
|
> Reduced
THDI
The THDI value indicates the level of harmonic
currents upstream of UPSs. THM offer better performance than all
other harmonic-suppression techniques.
> Increased power factor (PF) and cos
phi
THM can be set to improve the cos phi value.
The power quality obtained ensures optimum operation of theentire
power supply system.

|
> Operating
cost savings
Power consumption (kVA) may be
reduced by up to 20%.This reduction
makes it possible to:
-reduce the size of engine generator
sets and cables;
-enhance the operating reliability of
circuit breakers;
-reduce losses. |
Constant level of performance even at
low UPS loads
THM provides a virtually constant level of performance, whatever
the percent load on the UPS.
With this significant reduction in harmonics, it is possible to
implement all system architectures, in particular parallel-connected
configurations. In such configurations where the UPS does not supply
its total capacity,THM maintains high level of performance, contrary
to the double bridge technique.
Complete compatibility between the UPS
and an engine generator set
An engine generator set installed upstream of the UPS is often the
first equipment to suffer from harmonic disturbances. Due to its
capacity to eliminate harmonics even at low percent loads,THM ensures
optimum operation of engine generator sets.
Flexible and modular
Associated with group of UPSs, THM reduces
the footprint compared to traditional solutions.
Compliance with IEC standards
THM complies with the specifications of IEC guide 61000-3-4. Its
performance exceeds requirements and even anticipates on the requirements
of future standards.
