DC Surge Protection Relays for Solar PV Installations

Description

Protect your solar investment with the best DC surge arresters designed for Solar Photo-Voltaic installations
The surge protection relays protect installations and eliminate the effects of power surges.
They offer the highest level of security in low voltage lines, continuous processes, domestic and tertiary facilities, etc.
They are suitable for manufacturers and system integrators of industrial equipment, photovoltaic applications, wind turbines, etc.
Devices connected to the mains are increasingly susceptible to electrical disturbances in the grid. Hence it is essential to provide adequate protection to avoid major economic and material losses.
The most visible and destructive power surges are often caused by atmospheric discharges (lightning strikes). However, the main sources of surges are within the facility installation itself, for the following reasons:
·
Performance of circuit breakers and fuses.
·
Connection and disconnection of inductive loads.
·
Switching of motorsand machines.
·
Electrostatic discharge.
·
Capacitor’s power factor correction.
·
Energy transfers in generator sets.
BENEFITS
·
Compact equipment for wind power installations.
·
High discharge capacity via zinc oxide varistors and gas dischargers.
·
With thermal separation device.
·
Visual indication of a fault in the equipment.
·
Remote signaling of protection status.
·
Plug-in protection modules which facilitate maintenance.
