FAQ

1.What are the different types of Dc surge protectors?
There are two main types of DC surge protectors: 

• DC surge arresters: These are used to protect against high-energy surges, such as those caused by lightning strikes.
• DC surge filters: These are used to protect against low-energy surges, such as those caused by switching transients.
•  
• 2. How to Properly Configure SPDs in Dc Systems?
• Surge protective devices (SPDs) are used to protect electrical equipment from damage caused by voltage surges. In DC systems, SPDs are especially important because DC systems are more susceptible to voltage surges than AC systems.
  There are a few key things to keep in mind when configuring SPDs in DC systems:
  Select the right type of SPD. There are two main types of SPDs: surge arresters and surge filters. Surge arresters are designed to protect against high-energy surges, such as those caused by lightning strikes. Surge filters are designed to protect against low-energy surges, such as those caused by switching transients.
   Size the SPD correctly. The size of the SPD will depend on the amount of surge energy it needs to be able to withstand.
  Install the SPD properly. The SPD must be installed in a location where it will be protected from the elements and where it will have a good ground connection.
  Here are some additional tips for configuring SPDs in DC systems:
  Use SPDs with a high enough voltage rating for the DC system.
  Use SPDs with a low enough let-through voltage to protect the sensitive equipment.
  Use SPDs with a fast enough response time to protect against fast-rising surges.
  Use SPDs with a long enough life expectancy to provide years of protection.
  By following these tips, you can help to ensure that your DC system is properly protected from voltage surges.

3. Where should DC surge protectors be installed?

DC surge protectors should be installed in all areas where sensitive equipment is present. This includes areas such as:
Data centers
Telecommunications facilities
Industrial control systems
Medical facilities

4. What are the benefits of using Dc surge protectors?

DC surge protectors offer a number of benefits, including:

• Protection against damage to sensitive equipment
• Increased uptime for critical systems
• Reduced maintenance costs
• Improved safety for personnel
•  

5. What are the three classes of Dc surge protectors?

DC surge protectors are classified into three classes based on their ability to withstand different levels of surge energy. The three classes are:

Class I: These surge protectors are designed to withstand the highest level of surge energy, such as those caused by lightning strikes. They are typically used in critical applications, such as data centers and telecommunications facilities.

Class II: These surge protectors are designed to withstand medium levels of surge energy, such as those caused by switching transients. They are typically used in commercial and industrial applications.

Class III: These surge protectors are designed to withstand low levels of surge energy, such as those caused by everyday use. They are typically used in residential applications.
 

Here are some additional things to consider when choosing a DC surge protector:

• The type of surge protector: There are two main types of DC surge protectors: surge arresters and surge filters. Surge arresters are used to protect against high-energy surges, while surge filters are used to protect against low-energy surges.
• The size of the surge protector: The size of the surge protector will depend on the amount of surge energy it needs to be able to withstand.
• The features of the surge protector: Some surge protectors come with additional features, such as status indicators and remote monitoring capabilities.

When choosing a DC surge protector, it is important to consider your specific needs and requirements.

6. Steps to Ensure Equipment is Not Damaged by Voltage surges

Voltage surges can cause significant damage to electrical equipment. By taking the following steps, you can help to protect your equipment from damage:

1. Ensure that your system and SPDs have a good, low-impedance ground connection.

A good ground connection is essential for the proper functioning of SPDs. Without a good ground connection, the SPD will not be able to effectively dissipate the energy from a voltage surge.

2. Match the SPD to the input of the power conversion equipment you are protecting by making sure the "Uc" voltage in the SPD datasheet is equal to or slightly higher than the maximum continuous voltage on the protected conductor or the maximum rated voltage of the connected power equipment.

If the "Uc" rating of the SPD is much higher than the maximum rated voltage of the connected power equipment, it will not be able to effectively prevent voltage surges. The SPD will protect the device or equipment by activating at a voltage that is much higher than the maximum continuous operating voltage "Uc" and will not cause interference at voltages below "Uc".

3. ONCCY recommends protecting at least the PV module input of the inverter and, if using the public grid, the AC input should also be protected.

This is because the PV modules and the AC input are both susceptible to voltage surges. By protecting both of these inputs, you can help to ensure that your entire system is protected from damage.

4. If used for PV module loops, make sure the SPD is rated for the DC voltage, and if used for AC input, make sure the SPD is rated for the AC voltage.

It is important to use an SPD that is rated for the correct voltage. Using an SPD that is not rated for the correct voltage can damage the SPD and void the warranty.

By following these steps, you can help to protect your electrical equipment from damage caused by voltage surges.

7. Are Surge Protectors and Lightning Arresters the Same Thing?

No, surge protectors and lightning arresters are not the same thing.

Surge protectors are designed to protect electronic devices from damage caused by power surges. Power surges can be caused by a variety of factors, including lightning strikes, switching transients, and ground faults. Surge protectors work by diverting excess energy away from sensitive equipment. They do this by using a variety of components, such as varistors, metal oxide varistors (MOVs), and thyristors.

Lightning arresters are designed to protect buildings and other structures from damage caused by lightning strikes. Lightning arresters work by providing a path for lightning to travel to the ground safely. They are typically installed on the roof of a building or on a nearby structure.

Here is a table summarizing the key differences between surge protectors and lightning arresters:

Feature	Surge Protector	Lightning Arrester
Purpose	Protects electronic devices from power surges	Protects buildings and structures from lightning strikes
Location	Installed near sensitive electronic equipment	Installed on the roof of a building or on a nearby structure
Technology	Uses varistors, MOVs, and thyristors to divert excess energy	Provides a path for lightning to travel to the ground safely

It is important to use both surge protectors and lightning arresters to protect your property and equipment from damage. Surge protectors should be installed near sensitive electronic equipment, while lightning arresters should be installed on the roof of a building or on a nearby structure.

Here are some additional tips for protecting your property and equipment from lightning strikes:

• Keep trees and shrubs trimmed away from your home.
• Install a lightning rod on your roof.
• Unplug electronic devices during thunderstorms.
• Avoid using electronic devices during thunderstorms.

By following these tips, you can help to protect your property and equipment from damage caused by lightning strikes.
