3.Key Features & Advantages

1. Unmatched Electrical Stability

Our 110kV CVT uses high-quality dielectric materials and an optimized capacitor stack design, achieving a 3PT1-level transient response (residual voltage <2%). This ensures compatibility with fast-acting relays during grid faults.

2. Built for Harsh Environments

With dry arc distances exceeding industry norms and anti-pollution coatings (IEC 60815), the CVT operates reliably in coastal or industrial zones prone to salt, dust, or chemical contamination.

3. Precision You Can Trust

Patented damping technology and 0.1-class accuracy terminals allow on-site recalibration, maintaining measurement precision over a 30+ year lifespan.

4. Safety First

Hermetic sealing and SMC vacuum-cast terminals eliminate oil leaks, while ferroresonance suppression guarantees stable operation under varying loads.

4.Real-World Applications

Be used in a wide range of industries.

Industrial Plants

Eliminate power factor penalties in CNC machines and assembly lines while handling surge currents up to 100x rated capacity.

Substation

Stabilizes substation voltage against harmonics and intermittent generation from renewable inverters.

Commercial Buildings

Retrofit aging systems in hospitals or malls with silent (<45dB), flame-retardant capacitors that meet NFPA 70 fire codes.

5.How It Works?

The 110kV Capacitive Voltage Transformer converts high transmission-line voltages to safer, measurable levels using a capacitor divider and electromagnetic circuit. Its modular design includes:

1. High-Voltage Capacitor: Insulated with ultra-low-loss dielectric material.

2. Intermediate Transformer: Ensures precise signal scaling.

3. Damping System: Suppresses ferroresonance and voltage spikes.

6.Manufacturing & Quality Assurance

Every 110kV CVT undergoes 12+ quality checks, including:

Material Testing: X-ray inspection of capacitor elements.

8.FAQs

Q1: How does the CVT handle voltage transients?

A: The damping system limits residual voltage to <2%, meeting 3PT1 requirements for relay compatibility.

Q2: Is recalibration possible without de-energizing?

A: Yes! Our external accuracy terminals allow safe adjustments during live-grid operation.

Q3: What’s the maintenance interval?

A: Hermetic sealing ensures maintenance-free operation for 10+ years. Annual visual inspections are recommended.
