What happen when you use 6.6kV instead of 11kV surge arrester?
The 6.6KV device will conduct before the 11KV device, quite possibly even in normal operation. Don't use it this way!
How does lighting arrester working?
A lightning arrester (or lightning rod) works by providing a low resistance path to earth. This directs a lightning strike down the side of a building instead of it spreading through the electrical system.
What is surge divertor?
Surge diverters are normally located on the terminal pole of an overhead line system, and are intended to protect terminal equipment (e.g. transformers, cables, etc.) from sudden surges in voltage. Each of the line conductors is normally connected to earth, via the surge diverter. Under normal circumstances, the internal resistance of the surge diverter is high enough to insulate the line conductor from earth. However, if a voltage surge occurs due, for example, to a lightning strike, then the resistance of the surge diverter will collapse, 'diverting' the surge to earth.
What is surge capacitor and how it will works?
A surge capacitor is used to mitigate (minimize) voltage surges. Capacitor impedance can be modeled as 1/jwC, j = i = imaginary value used in vectors, w is the frequency, and C is the capacitance. A fairly small capacitor on the input to a power supplying circuit will have a large impedance, and so will impact the circuit operation very little due to the low power frequency. Surges are high frequency. When a surge occurs, the capacitor impedance appears much smaller to the high frequency surge, effectively shunting the surge energy to ground; this minimizes the surge with respect to the protected circuitry.
What are five types of surge arrester?
There five types of surge arrester: 1. Rod gap arrester 2. Horn gap arrester 3. Protector tube or expulsion type 4. Thyrite lighting arrester 5. Gapless arrester or metal oxide arrester
What will you do if the surge arrester is damaged?
Replace it.
How can you rate surge arrester?
check NEC
Where be the surge arrester be placed?
Before the object on the positive and after on negetive
What is the effect of surge arrester on increase the voltage in medium voltage circuits?
What is the effect of surge arrested on increase the voltage in medium voltage circuits?
What is MCOV rating for lightning arrester?
The MCOV (Maximum Continuous Operating Voltage) rating for a lightning arrester is the maximum voltage that the arrester can continuously withstand without failing. It is important to select a lightning arrester with an appropriate MCOV rating to ensure that it can effectively protect against overvoltage events without being damaged.

How the voltage arrester works?
The voltage arrester works by conducting when there is enough voltage to turn it on. Often, an arrester on a primary distribution circuit has a spark gap to ground, so that lightning strikes are limited in voltage, protecting the circuit. Other types of arresters, such as MOV's, can be used in surge protectors.
What is difference between surge absorber and surge suppressor?
There is likely no difference. Neither is accepted terminology for a surge suppressive device (SPD). If these products have been tested by safety organizations such as CSA (Canada) or UL (US) or tested to international surge standards (IEEE, IEC), then they should bare the correct terminology, otherwise, they are not tested to provide protection to equipment during a surge. Surge Absorber acts as a load that utilizes the high current until it exhausts. but the surge suppressor diverts the high current into ground without reaching the sensitive parts of the circuit. Surge absorber degrades faster than a surge suppressor.

The 6.6KV device will conduct before the 11KV device, quite possibly even in normal operation. Don't use it this way!
How do you change a lightning arrester to iridium?
To change a lightning arrester to iridium, you would need to replace the existing lightning arrester component with one made from iridium material. This may involve removing the old lightning arrester and installing a new one that is designed with iridium. It is crucial to ensure that the replacement arrester is compatible with the existing system and meets the necessary safety standards. Consulting a professional electrician or engineer for guidance is recommended.
