Product descriptions from the supplier
The NOV type self resetting overvoltage and undervoltage protector is an intelligent distribution protection device, with the core function of monitoring line voltage. When the voltage exceeds the safe range (undervoltage 140V-210V, overvoltage 230V-300V), the power can be automatically cut off within 0.5 seconds; After the voltage returns to normal, it will automatically reconnect after a preset delay (adjustable from 1-600 seconds) without the need for manual intervention throughout the process. Its IP20 protection level meets the installation requirements of conventional distribution boxes.
Advantages of NOV type self resetting overvoltage and undervoltage protector:
1. Accurate protection: With an error range of ± 2%, the protection action is precise and reliable.
2. Quick response: The delay of overvoltage and undervoltage action is only 0.5 seconds, quickly cutting off the dangerous power supply.
3. Flexible self recovery: Adjustable reset time of 1-600 seconds, suitable for different device restart needs.
4. Durable and long-lasting: up to 100000 electrical cycles and 1 million mechanical cycles, with stability.
5. Wide compatibility: Suitable for AC 220V/50-60Hz power grid, with strong applicability.
Product features of NOV type self resetting overvoltage and undervoltage protector:
1. Wide threshold protection:
Undervoltage protection covers 140V to 210V, while overvoltage protection covers 230V to 300V, effectively responding to various voltage abnormal scenarios.
2. High precision monitoring:
± 2% error control, accurate voltage judgment, avoiding misoperation or leakage protection.
3. Quick response mechanism:
After detecting abnormal voltage, it only takes 0.5 seconds to complete the power-off action, reducing the risk of equipment damage.
4. Intelligent reset:
Provide flexible reset delay settings ranging from 1 second to 600 seconds to meet the safe restart interval requirements of various electrical appliances such as air conditioners and refrigerator compressors.
5. Double long-life design:
The electrical components have a breaking life of 100000 times, and the mechanical structure supports up to 1 million operations, ensuring long-term stable operation.
6. Standard protection:
IP20 shell protection effectively prevents large solid foreign objects from entering, suitable for installation in standard distribution box environments.

How Does Oil Loss Affect SF6 Relay Performance?1.SF6 Electrical Equipment and the Common Problem of Oil Leakage in SF6 Density RelaysSF6 electrical equipment is now widely used in power utilities and industrial enterprises, significantly advancing the development of the power industry. The arc-quenching and insulating medium in such equipment is sulfur hexafluoride (SF6) gas, which must not leak. Any leakage compromises the reliable and safe operation of the equipment, making it essential to monitor the SF6 gas density. Currently, mechanicalFelix Spark10/21/2025 -

Grounding Causes of Cable Lines and the Principles of Incident HandlingOur 220 kV substation is located far from the urban center in a remote area, surrounded primarily by industrial zones such as Lanshan, Hebin, and Tasha Industrial Parks. Major high-load consumers in these zones—including silicon carbide, ferroalloy, and calcium carbide plants—account for approximately 83.87% of our bureau’s total load. The substation operates at voltage levels of 220 kV, 110 kV, and 35 kV.The 35 kV low-voltage side mainly supplies feeders to ferroalloy and silicon carbide plantsFelix Spark10/21/2025 -
