Frequently Asked Questions
Q
What is the primary function of the 10 kV zinc oxide arrester (model 17/50)?
Its primary function is to protect electrical equipment from overvoltage damage caused by lightning strikes, switching operations, and power system anomalies. It achieves this by rapidly conducting excess voltage energy away from connected equipment, maintaining system safety and reliability.
Q
What types of overvoltage can this arrester protect against?
This arrester is designed to handle three main types of overvoltage: atmospheric overvoltage (such as those caused by lightning strikes), operating overvoltage generated during switching operations, and power frequency transient overvoltage resulting from power system operational anomalies.
Q
Why is zinc oxide used as the core material in this arrester?
Zinc oxide resistor sheets are used because of their outstanding nonlinear volt-ampere characteristics. Under normal operating conditions, they allow only microampere-level current to pass, causing minimal interference to connected equipment. During overvoltage events, they instantly conduct thousands of amperes, providing rapid and reliable protection.
Q
In which industries or environments is the 10 kV zinc oxide arrester most commonly used?
This arrester is widely used across power systems (substations, distribution networks, transmission lines), railway electrification systems, communication networks, industrial and mining enterprises, and high-rise commercial or residential buildings — anywhere a 10 kV electrical system requires reliable overvoltage protection.
Q
What electrical equipment can this arrester protect?
The arrester is capable of protecting a wide range of electrical equipment, including transformers, switches, capacitors, motors, mutual inductors, generators, power cables, communication power supply equipment, and signal transmission equipment within 10 kV electrical systems.
Q
How does the 10 kV zinc oxide arrester contribute to insulation coordination in electrical systems?
By clamping overvoltage levels to within safe limits, the arrester plays a key role in insulation coordination — the process of matching the protective levels of arresters with the insulation strength of connected equipment. This ensures that no component in the system is exposed to voltages beyond its rated insulation capacity, extending equipment lifespan and system stability.
