What is the Relationship Between Raycap and Iskra Zascite?

German Raycap company acquired the Slovenian Giant manufacturer Iskra Zascite company in 2016 and incorporated it. Thus, an organization with the World’s widest range of protection products was created.

What is the Concept of Equipotential?

All grounds in facilities must be equipotential. Equipotential difference is the most serious reason that will cause fault currents to damage the facility. Lightning protection grounding must also be included in the equipotential system.

What are the Types of Grounding?

Functional grounding, Operational Grounding, Protection Grounding, Foundation Grounding basically constitute the types of grounding. Grounding types such as lightning protection systems are included in the concept of Functional grounding.

How Should Lightning Protection Grounding Be Done?

Lightning protection grounding should be done in the opposite direction of the facility, in a way that the impulse is divided into parts, and should be reduced to the order of 5 ohms.

What is the Rolling Sphere Method?

It is the calculation of the integrated protection of different lightning air terminals within the scope of a system. It is the system where lightning is depicted as a sphere and moved away from the building with air terminals. It is the system most frequently applied by Yılkomer.

What is the Protection Angle Method?

It is the calculation of the protection of a single air terminal. Basically, it is providing protection in the form of a cone.

What is the Catenary Wire Method?

It is a single protection conductor providing a cone-shaped protection area.

What is the Difference Between Lightning Rod and Faraday Cage?

Lightning rod systems are active systems, Faraday system consists of passive systems. Lightning rod system consists of a single head, Faraday system consists of the combined operation of many system equipment.

What is the most accurate method for Grounding Measurement?

Loop Impedance (Stakeless Measurement) is the method where we reach the most accurate result.

What is the most correct lightning protection method in Solar Power Plants?

Systems designed with Rolling Sphere Method and passive air terminals are the most correct method.

What is DC Surge Arrester?

These are products protecting DC systems starting from 5V up to 1000V. In solar systems, 1000V PV Surge Arresters and 12, 24, 48v power output protections are the most popular ones.

What is 100kA protection level?

It is the protection value against lightning impulse where the Iimp value is 100kA.

What is TYPE 1+2+3 LV Surge Arrester?

What is 4-way Lightning Protection?

It is a system consisting of LV Surge Arrester, External Lightning Protection, Grounding, and Equipotential system concepts.

What is Foundation Grounding?
