measurements, but it is recommended to use DC performance ratio
(R
P
, see IEC 61724) calculations to find “hidden” underperforming strings.
•
Detecting worn out surge protective devices: if the remote alert of a Weidmüller
SPD is wired to a digital input of the Transclinic, the Modbus client can detect SPD
cartridges that reached the end of their life.
• Detecting DC switch-disconnectors accidentally left open after a maintenance session
(a switch-disconnector with a dry contact must be used).
• Detecting combiner boxes with internal hot spots: thanks to the temperature
measurement function of the Transclinic, an accidental hot spot (i.e. a loose
connection) inside a combiner box can be remedied before it becomes a fire accident.
• Prioritizing maintenance actions: by combining all the measurements above, the
maintenance staff can better decide what tasks in the DC side have higher priority
due to the lost energy production or the risk level.
DANGER
If the Transclinic is used in a manner not specified by Weidmüller, the
protection provided by the equipment may be impaired.
WARNING
This equipment shall not be used for measurements on mains circuits.
For detailed ratings of the PV-side terminals please check the corresponding
section in this user guide as well as the product specifications in the annex.
Failure to observe this requirement will create an electric shock hazard.
NOTICE
Even though DC-side power and energy measurements can be derived
from the measurements taken with this equipment, the Transclinic is not
intended to be a power meter or an energy meter.
