15 kVar Capacitor Bank - Professional Power Factor Correction Solution

Product Introduction

Looking to improve your power factor and reduce electrical costs? Our 15 kvar capacitor bank offers the perfect solution for your facility's reactive power management needs. This high-performance electrical component is specifically designed to correct power factor issues in low voltage systems ranging from 400V to 690V. When you install our 15 kvar capacitor bank, you're investing in a proven technology that eliminates utility penalties for poor power factor, optimizes transformer capacity, and reduces energy losses throughout your distribution system. Your electrical infrastructure will operate more efficiently while delivering significant cost savings.

Technical Specifications

Main Features and Advantages

Self-Healing Technology

Your capacitor bank features advanced self-healing capability. When voltage breakdown occurs, the metallization instantly vaporizes around the fault point, isolating it within microseconds while maintaining continuous operation.

Built-in Safety Protection

The overpressure disconnector provides mechanical safety that automatically disconnects the capacitor from power supply during internal pressure buildup, preventing case rupture and ensuring operator safety.

Superior Dielectric System

Heavy-edge reinforced MPP film construction handles high current density while maintaining extremely low dielectric losses, ensuring maximum efficiency and longevity.

Discharge Resistors

Integrated discharge resistors safely reduce terminal voltage below 50V within 3 minutes after disconnection, protecting maintenance personnel and preventing equipment damage.

Practical Applications

Industrial Motor Compensation

Your 15 kvar capacitor bank works excellently for direct compensation of 15kW-30kW induction motors in HVAC systems, irrigation pumps, and conveyor belts, reducing reactive current flow and cable heating.

APFC Panel Integration

In automatic power factor correction systems, these units serve as precise switching steps that dynamically adjust to your facility's changing load conditions, preventing over-compensation during low-load periods.

Harmonic Filtering Applications

When paired with detuned reactors, the capacitor bank prevents harmonic resonance in facilities with variable frequency drives and UPS systems while maintaining excellent power factor correction.

How It Works

Your capacitor bank generates leading reactive current that directly counters the lagging inductive current produced by motors and transformers. This reactive power injection brings your power factor closer to unity (1.0), reducing the total apparent power drawn from the utility.

The metallized polypropylene dielectric stores electrical energy in its electric field. When connected across your electrical supply, it provides a low-impedance path for reactive current, effectively reducing the reactive power burden on your distribution system.

FAQ

What cable size do I need for installation?

Use minimum 6mm² or 10mm² copper cable rated for at least 1.43x the nominal current (approximately 31A for 400V units) to handle harmonics and tolerance variations.

Can I use this in high harmonic environments?

If your total harmonic distortion exceeds 5%, choose a higher voltage rated unit (440V or 480V) with appropriate detuned reactors to prevent overheating and resonance.

How do I verify proper operation?

Measure phase current with a clamp meter. A healthy 400V unit should draw approximately 21.6 amps. Significantly lower readings indicate dielectric degradation.

What's the expected lifespan?

Under standard conditions below 55°C ambient temperature, expect 100,000-130,000 operating hours. Higher temperatures or excessive harmonics can reduce this by 50%.

Why is the discharge resistor important?

Safety regulations require voltage reduction to below 50V within 3 minutes after disconnection. This prevents dangerous arcing and protects personnel during maintenance.
