General Overview:
The document describes an intelligent low voltage power capacitor compensation module designed by Hengyi Electric Group. It aims to reduce line loss, improve power factor, enhance power quality, and save energy. The module is available in capacities of 60 kvar, 120 kvar, and 180 kvar, and features automatic control, measurement functions, and multiple protections.

Specifications:
- Rated working voltage: 380V ± 20%
- Rated frequency: 50Hz
- Ambient temperature: -25℃ to +55℃
- Altitude: ≤2500m
- Relative humidity: 40% ≤50%; 20% ≤90%
- Environmental conditions: No noxious gas, vapor, conductive or explosive dust, or violent mechanical vibration.

Design and Installation:
The module is compact, with simple wiring and flexible installation. It can be mounted inside a power distribution cabinet and operates independently, ensuring high reliability even if one capacitor fails.

Functional Features:
- Automatic control with zero passage switching
- Measurement of voltage, current, reactive power, power factor, and internal temperature
- Protections include overcurrent, overvoltage, undervoltage, overheating, open-phase, and three-phase imbalance.

Advantages:
The module helps in reducing electricity costs by achieving national power factor standards, thus avoiding fines. It also reduces line consumption, active power loss, and voltage drop, improving equipment utilization and power supply quality.

Management and Benefits:
- Three-phase unbalance management to prevent heating and aging of lines and avoid equipment errors.
- Harmonic management to improve power supply quality, reduce equipment heating, and extend service life.
- Field measurements and harmonic illustrations are provided to diagnose issues related to harmonics, low power factor, and phase unbalance.

Ordering Notes:
Users should provide parameters such as rated voltage and capacitance when ordering.
