Targeted protection of secondary circuits:
Specially used to protect the secondary circuits of voltage transformers in power systems. It can monitor the secondary voltage in real time and respond quickly to overvoltage conditions.
Quick and reliable action:
When the secondary voltage exceeds the set value, it can act quickly to effectively limit the overvoltage amplitude and protect the secondary equipment from the impact of excessive voltage.
Multiple protection modes:
It has multiple protection functions, such as phase-to-phase overvoltage protection, phase-to-ground overvoltage protection, etc., to provide comprehensive protection for the secondary circuit.
Advantages:
Guarantee the safety of secondary equipment:
Effectively prevent the secondary overvoltage caused by lightning strikes, system failures, etc. from damaging secondary equipment such as relay protection devices, measuring instruments, and communication equipment, and ensure the normal operation of secondary equipment.
Maintaining stable operation of the system:
The normal operation of secondary equipment is an important guarantee for the stable operation of the power system. The protector can avoid false operation or refusal to operate caused by secondary equipment failures, and improve the reliability of power system protection.
Easy to install:
Compact structure, easy installation, can be easily connected to the secondary circuit of the voltage transformer, and does not require large-scale transformation of the existing power system.
Application:
It is widely used in the secondary circuit protection of power systems such as substations, power plants, and distribution rooms of various voltage levels. It is an indispensable device to ensure the safe operation of secondary equipment in power systems.
A reliable Secondary Overvoltage Protector is an essential component for safeguarding modern electrical infrastructure against unpredictable voltage spikes. Modern power grids are increasingly complex. Therefore, integrating high-quality surge arresters is critical to maintaining the stability of intelligent electricity monitoring and protection systems. These specialized devices protect switch cabinets, sensitive electrical devices, and control circuits from damaging over-voltage conditions. By instantly mitigating transient surges, they prevent costly equipment failures. This ensures continuous operation across the global power industry.
Our protection devices feature robust technical superiority to meet rigorous global safety standards. We focus on delivering utility-grade reliability. This ensures every unit withstands extreme electrical stress while providing consistent protection for your valuable infrastructure.
To guarantee long-lasting performance, every unit undergoes multiple testing phases within our factory before deployment. This strict quality control process ensures our surge protectors deliver reliable results under extreme conditions. By simulating real-world transient voltage events, we verify that each device reacts instantly. This protects your circuits and minimizes maintenance costs.
Modern electrical setups require components that work together without interference. Our protectors are engineered for flawless integration alongside intelligent switch cabinet control devices and multi-functional power meters. This seamless compatibility ensures your entire monitoring ecosystem remains fully protected. It does so without compromising daily operational efficiency.
These devices are deployed across various industrial environments where operational continuity is non-negotiable. From utility substations to commercial manufacturing facilities, they provide critical defense. They block transient voltage spikes that can disrupt sensitive equipment.
In large-scale utility networks, protecting secondary AC circuits is vital for grid stability. Surge arresters are strategically installed to absorb and dissipate excess energy. This prevents surges from reaching downstream transformers and control systems. This application is crucial for maintaining power supply integrity during severe electrical storms.
Within intelligent switchgear, transient voltage spikes pose a significant threat to microprocessors. A dedicated secondary overvoltage protector safeguards sensitive internal components. These include intelligent temperature and humidity controllers and wireless monitoring systems. By neutralizing surges at the source, we ensure your automated control panels function safely.

| Selection Factor | Description | Importance for Power Systems |
|---|---|---|
| AC Circuit Specifications | Match the protector's voltage rating to the nominal voltage of your secondary circuits. | Prevents premature degradation or failure to trigger during a surge event. |
| Maximum Continuous Operating Voltage (MCOV) | Ensure the MCOV is slightly higher than the system's normal operating voltage. | Guarantees the device remains inactive during standard daily operations. |
| Environmental Conditions | Consider temperature, humidity, and enclosure types like switch cabinets. | Ensures long-term durability and reliable performance in harsh industrial settings. |
| Integration Requirements | Verify compatibility with existing power meters and status indicators. | Maintains seamless operation of intelligent power system products. |
