3. Product Main Features

1. Intelligent automatic control

   Equipped with automatic control function, it can detect system voltage and reactive power in real time, automatically switch capacitor banks, and realize closed-loop power factor control without manual intervention.

2. Four Remote Remote Control

   Supports remote signaling, remote metering, remote regulation and control, can be connected to an integrated automation system substations for remote centralized monitoring and operation.

3. Full-length safety protection

   Equipped with a microcomputer protection unit for the capacitor bank, which accurately protects against overvoltage, overvoltage, internal faults and other risks, completely eliminating malignant accidents such as fire and explosions.

4. Flexible scenario adaptation

   Modular design, supports indoor/outdoor installation, fixed compensation/automatic group compensation, adaptable to complex distribution systems with multiple capacitor banks on two bus sections.

5. Harmonic suppression capability

   Can match series reactors with different reactance rates based on the user's on-site harmonic conditions, effectively suppressing the impact of harmonics on capacitor banks and ensuring equipment safety.

6. High-reliability design

   Equipped with a special switch, supports frequent operation and prevents switching bounce; Series reactors can flexibly use dry iron core, iron core, dry-type air core, and other designs to adapt to various installation conditions.

7. Custom delivery

   Can be flexibly assembled according to customer needs and transportation requirements, supporting non-standard capacity, special protection levels, and other customized solutions.
