SURYA POWER INDUSTRIES -SPI GUARD ESE LIGHTNING ARRESTER

• This model anticipates lightning strikes within its protection radius by means of an internal ion production system. The technical characteristics include a length of 63 cm, an external diameter of 187mm, a weight of 4.20 kg, and a construction made of stainless steel. With a maximum current withstand of 200kA, it has been tested and certified to comply with the NFC 17-102/201 etc.

An ESE Lightning Arrester refers to an Early Streamer Emission (ESE) Lightning Arrester, which is a type of lightning protection system designed to capture lightning strikes more effectively than conventional lightning rods.

 What is an ESE Lightning Arrester?

An ESE Lightning Arrester is a device installed at the highest point of a structure to intercept lightning strikes and safely conduct the electrical discharge to the ground. It is designed to initiate the upward leader earlier than other objects around, increasing the protected area.

 How It Works

1. Charge Accumulation: During a thunderstorm, the arrester accumulates ambient electric charge.
2. Early Streamer Emission: When the field strength reaches a certain threshold, the ESE device emits an upward streamer earlier than other nearby objects.
3. Interception: This early emission attracts the lightning strike to the ESE terminal.
4. Discharge Path: The lightning current is safely conducted to the ground via a down conductor and earthing system.

 Benefits of ESE Arrester

• Greater Coverage: Provides protection to a larger radius compared to conventional rods.
• Efficient Protection: Triggers earlier, increasing the likelihood of intercepting a strike.
• Low Maintenance: Typically robust and requires minimal upkeep.
• Standards Compliant: Usually adheres to standards like NFC 17-102 or UNE 21186.

 Protection Radius

The radius depends on:

• Height of the ESE above the structure
• Level of protection (I, II, III, or IV)
• The ?T (time advance) of the ESE terminal (e.g., 15 µs, 30 µs, 45 µs, 60 µs)
