Capacitor compensation acts like a "power assistant" for circuits, improving energy efficiency. In AC systems, inductive loads (e.g., motors, transformers) create "lazy current" (reactive power), wasting energy and increasing costs. Capacitors counteract this by synchronizing voltage and current, reducing waste and extending equipment life.

Key Benefits:

1.Cost Savings: Boost power factor from 0.7 to 0.95, cutting electricity bills by 5–20%.

2.Equipment Protection: Reduce heat generation and line losses.

3.Capacity Expansion: Enable 30% more load capacity on existing circuits.

FAQ: Capacitor Compensation Basics

Q1: How do capacitors compensate?
Capacitors generate "positive energy" (capacitive reactive power) to neutralize the "negative energy" (inductive reactive power) from motors, aligning voltage and current phases.

Q2: Pros and cons of capacitor compensation?

✅ Pros: Flexible installation, low maintenance, cost-effective (0.4% energy loss).
❌ Cons: Limited adjustment precision, overheating risks (>70°C may cause explosions), sensitivity to voltage fluctuations.

Q3: Which compensation method to choose?

Factory floors → Decentralized low-voltage compensation (localized, load-dependent).

Buildings → Centralized low-voltage compensation (automatic control in distribution rooms).

High-voltage users → Centralized high-voltage compensation (10kV substation-level).

Safety & Operation Guidelines:

1.Current/Voltage Limits: Never exceed 1.3× rated current / 1.1× rated voltage.

2.Temperature Control: Housing ≤55°C, internal ≤70°C.

3.Explosion Prevention: Install fast-acting fuses (1.5–2× current rating).

4.Maintenance Checks: Monthly phase current balance (<5% deviation), inspect for bulging/leaks.

5.Power Cycling: Wait 3 minutes after shutdown to restart (prevents residual charge explosions).
