OBO – Surge protection

OBO – Surge protection, what is OBO surge protection device?

Surge Protection Devices or SPDs are lightning protection devices created to protect electrical equipment when voltage suddenly increases.

Surge arresters and surge suppressors are used in this system with high efficiency.

What is Surge Lightning?
Surge lightning is when lightning strikes a certain location, within a radius of 2km from the lightning strike location, all metal objects, electrical wires, and data transmission lines will experience electromagnetic induction leading to damage.

What is OBO Surge Protection Device?
Surge Protection

Surge protectors are devices that limit the spread of transient overvoltages on power lines by safely diverting this dangerous current elsewhere.

They contain at least one nonlinear component. Single-port SPDs are connected in parallel or two-port SPDs are connected in series.

Understanding Surge Protection Systems
Surge protection systems are designed to limit sudden overloads arising from the atmosphere and transmit current (waveform) to the ground. SPDs help limit the amplitude of this overload voltage to a certain value that does not cause damage to electrical installations and electrical switching equipment as well as control devices.

Surge protectors eliminate overvoltages in the event of:

In normal mode, between phase neutral or ground.
In split mode, between phase and neutral.
In the event of an overvoltage exceeding the operating threshold, the surge protector will:

Conduct energy to ground in normal mode.
Distribute energy to other conductors in split mode.
Classification of OBO Surge Protection System
– Surge protection, surge protection devices are divided into 3 types, specifically as follows:

SPD Type 1
Type 1 surge protection device is recommended for use in specific cases such as factories, buildings, industrial plants, etc. that are protected by lightning protection systems or direct lightning protection grid cages.

This device protects the electrical system. Type 1 SPD is capable of discharging the reverse current caused by lightning surges that travel back from the earth conductor to the electrical system conductor.

Type 1 surge protection devices are characterized by 10/350µs waveform currents.

SPD Type 2
Surge protection device type 2 is the primary protection system for all low voltage electrical equipment. It is installed in each electrical panel to prevent overvoltages from spreading in the electrical system and protect the loads.

OBO – Surge protector, type 2 surge protector is characterized by 8/20µs waveform current.

Type 3 SPDs
Type 3 surge protectors have low discharge capacity. Therefore, they must be installed as a supplement to Type 2 SPDs and in the vicinity of sensitive loads.

Electrical Equipment Fanpage is updating… Type 2 surge protection is characterized by a combination of voltage waves (1.2/50µs) and current waves (8/20µs).
