Surge protectors SURGYS
G51-PV
The Socomec's surge protectors SURGYS
G51-PV are conceived
to assure the protection of photovoltaic networks. They act against
overvoltages due to the lightning. These surge protectors do the
protection in Common Mode (type G51-500PV and G51-600PV) or
both Common and Differential Mode (type G51-800PV and G51-
1000PV). In accordance with relevant standards, the SURGYS
integrate a built-in thermal disconnector.
Choice of surge protection and coordination
Insure consistently - before all implantation - that the choice of this
surge protector is adapted to the following requirements :
•
to actual regulations and standards.
•
to the Socomec recommendations (see our catalogue about
surge protector).
Connection to the network
This surge protector permits to protect a Photovoltaic DC network. It
is set in parallel to the network to be protected, mostly integrated in a
special enclosure near the photovoltaic inverter.
Setting the surge protector
The installation of surge protectors shall only be done by qualified
and respectful people to the Socomec recommendations and in
particular of the present document.
For certain insulation measurements or dielectric tests, the
disconnection of surge protectors can be necessary in order to avoid
to influence measures or to accelerate the ageing of surge
protectors.
•
Surge protectors must be connected between the active
conductors (L+, L-) and the PE
•
The wiring between phases active conductors and equipotential
crossbar must be as shortest as possible (max. 0.5m – please
report to the technical pages of our catalogue).
•
The section of the cable connected to the PE must be minimum
6 mm
2
•
The non-protected cables must not be install in parallel with the
protected cables in order to avoid couplings.
Liability
The surge protector SURGYS
doesn't require a particular
maintenance, nevertheless the periodic verification of their state is
recommended.
In case of exceptional life end of the surge protector, the
disconnection of the surge protector of the network is signalled by a
mechanical indicator. As soon as the mechanical indicator turns to
red, the surge protector cartridge must be replaced (m-G51).
A remote signalling of disconnection is also available: NC contact
11-12 (or NO contact 14-11) = functional surge protector.
