The surge protector device is a device that limits the surge current and repeats the same as specified. This is a cost-effective solution that helps prevent downtime, improve the system and data reliability, and eliminate equipment damage through transients and surges.
Surge Protective Device Applications:
They work in power distribution, control cabinets, electronic motor controllers, equipment monitoring, metering, medical equipment, backup power, etc.
When it comes to home appliances, you can use surge protector devices in communication circuits, cable TV feeds, security systems, alarm systems, stereo equipment and other appliances in the kitchen or household as well.
People use it in hospitals, schools, water treatment plants and also telecommunication facilities.
They help avoid utility switching and the switching of electric motors.
In addition, they help in connecting computer devices to a single source of power.
Before the introduction of search protection devices, people utilize coils, motors, resistors, etc., to protect the equipment from any surge. However, when the new devices came into the market, new technology for this purpose also arose. Two devices that are the surge protector and the surge arrester, later came into existence. They protect the wires, transformers, and various equipment from lightning. Also, they are responsible for maintaining the voltage below the insulation level. They both work in the same way with minor differences.
Surge Protective Device for the DC side of Photovoltaic systems: The characteristics of photovoltaic systems differ a lot from traditional DC sources. PV sources have a non-linear characteristic which leads to long-term persistence when it comes to ignited arcs. Hence, PV current requires larger switches, fuses, and requires a disconnector for the SPD. This disconnector is then adapted in a unique nature to cope with the PV currents.
DC SPD surge protective device, protect against lightning surge voltages in solar system (photovoltaic power supply system).These units must be installed in parallel on the DC networks to be protected and provide common and different modes protection.
