Noise and noise level
The inductive elements as well as the fans on the TopCon low voltage
system produce a lower or higher noise level dependent on the
operating mode. However, in the immediate vicinity of the cabinet this
noise is under the tolerance limit that would make acoustic protection
equipment necessary.
The usage of acoustic protection equipment or acoustic insulation
measures can, however, be necessary in specific circumstances.
Mechanical damage
Incorrect operation of the systems can result in mechanical damage to
the downstream equipment and systems.
In particular, on the supply of power to drives it is to be ensured that
excessively high speeds cannot result on load shedding.
The monitoring of the maximum speed with intervention in the safety
chain is recommended above all if the system runs unmonitored.
Handling stores containing large amounts of energy
Modern energy storage systems are able to absorb very large amounts
of energy. This situation has the following consequences:
•
The cabling should not just comply with the maximum charging
and discharging currents to be expected, to some extent
significantly higher peak currents are to be expected during
switching processes.
•
Unlike the TopCon low-voltage system, which is fully current-
limited in both quadrants, in the case of stores containing large
amounts of energy a short-circuit or failure can be very serious.
Due to the high currents serious injuries and serious damage can
be caused.
The following, incomplete list indicates some of this damage:
1. Burning of wires and connectors
2. Sparking
3. Fires, insulation fires
4. Arcing, welding
5. Electric shocks
