Solar PV System Needs Surge Protection

Surge protection devices help keep systems running smoothly and profitably. Solar arrays are just like electronic devices that we use. These are prone to surges in voltage that can harm its components, reducing its purpose to convert energy.

Power surge significantly happens when more voltage comes through wires into devices. Some reasons include electrical overload, faulty wirings, lightning strikes and restoration of electricity after an outage. A harmful incident can occur, and in the worst case scenario, may lead to burning of the establishment. 

Solar arrays are electronic devices that are also prone to damage from surges. Solar panels are prone to lightning due to its large surface area and placement in exposed locations. These are mostly mounted in open spaces.

If the solar panels are struck directly, severe damage happens. Lightning burns holes in the equipment and even causes explosions. Loss of a PV module will only mean a loss of a string. But loss of inverter is a loss of the power generation for a large section of the plant. The effects of lightning and other overvoltage are not always apparent. These events not only affect and destroy major modules and inverters, but also monitoring systems and tracker controls.

A surge protector prevents damage to electronics by diverting the overvoltage from the power line into a grounding wire. Random and unexpected failure of solar arrays due to surges could slow down financial return. Installing surge protection device networks throughout the solar array’s DC and AC distribution protects the system from critical surges.

SPDs have its certain limitations too. For example, SPD can not prevent damages from direct lightning strikes. Adding lightning protection device can be taken to further protect the system specifically from lightning.

Lightning Protection System for Diamed Enterprise

Diamed Enterprise Lightning Protection System

May 11, 2022 – PowerPro successfully designed, supplied, and installed a Cirprotec Lightning Protection System for Diamed Enterprise located in Santa Fe Subdivision, Batong Malake, Los Baños, Laguna. The package includes a Nimbus® 15 ESE Lightning Protection Rod, providing a protection radius of at least 51M. It guarantees overall building protection from lightning strikes. Diamed, a biomedical institute, needs the security from external electrical hazards like lightning strikes. LPS preserves the condition of their equipment resulting in quality and accurate results to its customers and stakeholders. 

A CDR-401 discharge counter from Cirprotec was also installed. It features a clip-on mounting system which enables ease of installation to either flat tapes or the down conductors of the system. Unlike other discharge counters available, Cirprotec’s CDR-401 are more portable and easy to transfer without requiring any destructive work. It is also IP67 rated, making it totally protected against dust and immersion.

A grounding system completes this package to safely discharge any lightning charge that has been caught by the LPS. This includes down conductors where the lightning charges will travel to the ground, a grounding rod which will discharge the electric charge caught, and a ground inspection pit for the ease of inspection and maintenance of the ground discharge system.

With Cirprotec LPS, Diamed Enterprise is guaranteed safe from lightning damage to both their structure, electrical system, and their plugged-in delicate devices. The enterprise invested wisely in Cirprotec Lightning Protection System, making sure that the business runs smoothly and  is secure from external electrical hazards. Safety and security surely make Diamed Enterprise perform the most advanced researches and provide cutting-edge technology.

Cirprotec Nimbus – Your Advantage in Protection

According to the NFPA, lightning strikes cause $451 million dollars in property damage each year. This number says a lot about how destructive and obviously frequent lightning strikes occur. It totally affects buildings which can either be residential or commercial. Businesses have more stakes in their daily and minutely operations. Hence, a destructive lightning strike can do more damage than just the physical structure. It may also adversely influence the business processes and profitability. This gives light to the importance of a Lightning Protection System.

Usually, businesses are situated in business  districts with high rise buildings, towering together and closer to the clouds. It makes these structures more prone to lightning strikes that aims to get discharged into the ground. Cirprotec Nimbus® ESE (Early Streamer Emission) Lightning Rods provide protection on structures that are prone to such. It conducts the strike’s electricity and directs it through a designated passageway consisting of wires to the ground. These wires are designed to transport the lightning charge away from the building, avoiding physical damage and short circuit on the electrical structure.  

Equipped with ESE technology, Cirprotec Nimbus® series gives an advantage in protection and lower overall cost since fewer rods are needed due to the device’s radius (approximately 120m) protection coverage.

PowerPro Installs Mersen Surge Protection Devices for Philippine Carabao Center

PowerPro Installs Mersen Surge Protection Devices for Philippine Carabao Center

The Philippine Carabao Center, an attached agency of Department of Agriculture whose responsibilities include the carabao development program implementation and livestock R&D, gets #PowerPROtected with surge protection devices.

PowerPro Philippines supplied and installed Mersen STPT12-12K275V-3P surge protection devices to protect all the loads and valuable equipment inside the PCC structure such as transformers, air-conditioning system, and computers. The facility is located in CLSU Compound, Science City of Muñoz, Nueva Ecija, and the installation was done in January 2021.

Mersen Surge-Trap® Pluggable STPT12 12.5kA is the series of combined Type 1+2/Class I+II devices for discharging lightning currents and protecting against voltage surges, in accordance with EN/IEC 61643-11.

The device is suitable as the first step of protection in incoming power supply panels and areas with exposure to the atmosphere, where installations are usually provided with an external lightning protection system.
