Features:

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.
