Basics of SPD that I haven't heard yet

Do you know the damage caused by the power of lightning? Lightning can destroy appliances and start fires. This time, Hakusan Inc. a specialized manufacturer, will explain in an easy-to-understand manner about the device "SPD (Surge Protective Device)" that prevents such damage from lightning.

What are SPDs?

SPD is an abbreviation for "surge protective device", and is a device that protects electrical equipment from lightning surges (rapid voltage fluctuations caused by lightning). They are often used in homes, offices, factories, etc. and play an especially important role during the thunder season.

how do you work

SPD has a mechanism to release excess voltage before lightning surge reaches electrical equipment.

Specifically, SPDs have built-in special elements called "varistors" and "lightning arresters" that limit excessive voltage and shunt it to the ground, etc., to protect electrical equipment.

By the way, varistors and lightning arresters normally do not conduct electricity, and they conduct electricity only when a high voltage is applied.

SPD type

There are three main types of SPDs.

1. Compatible voltage: Choose a voltage that is suitable for the electrical equipment in your home or office.
2. Surge withstand: How much current you can handle is important. It is important to choose one that can handle the appropriate surge resistance.
3. Limiting Voltage: See how small you can keep the lightning surge voltage.

SPD installation method

Installation of SPD requires electrical work, so please ask a professional for Class I and Class II.

Advantages of installing SPD

Installing an SPD has the following advantages:

1. Extending the life of electrical equipment: Protecting electrical equipment from lightning surges makes it less likely to break.
2. Improved safety: Accidents such as fire and electric shock can be prevented.
3. Economical: You can reduce costs and power wastage due to electrical equipment failure.

summary

Now you should have a basic understanding of SPD. Install an SPD to stay safe and secure during the thunderstorm season (especially June to August). It is important to choose the SPD that suits your situation and install it correctly. If you want to know more about SPD, please feel free to contact us, a professional manufacturer.
