Vacuum Circuit Breaker (VCB)

The 11/22/33KV Vacuum Circuit Breaker (VCB) Panel is designed for transformer protection, ensuring reliability and safety. Manufactured to meet strict industry standards, these panels are known for their superior quality and cost-effectiveness. VCB panels are available from original equipment manufacturers (OEMs) for new installations, repairs, retrofits, and upgrade projects.

How VCB Panels Work

A VCB panel is a type of circuit breaker where the arc quenching occurs in a vacuum environment. This technology is best suited for medium voltage applications. Although it can be used for higher voltages, it is not commercially viable.

Key Features & Materials

• Utilizes CuCr (Copper Chromium) for electrical contacts, ensuring high performance.
• Requires minimal maintenance compared to other relay control panels.
• Ideal for industrial, commercial, and power distribution applications.

Why Choose VCB Technology?

VCB is one of the most trusted and reliable current interruption technologies in medium voltage switchgear. Engineers continue to enhance its efficiency and durability, making it a preferred choice for modern electrical systems.

NGR PANEL

The NGR Panel houses a Neutral Grounding Transformer (NGT) and a Neutral Grounding Resistor (NGR), which are essential for grounding or earthing the neutral current during an unbalanced three-phase generator load. This setup ensures proper generator protection.

Functionality

The Neutral Grounding Transformer (NGT) steps down the voltage of the neutral bus from 6.6 KV, 11 KV, or 15.75 KV to 110V or 220V. This reduced voltage is then connected to a neutral grounding resistor and an earth terminal to bring the neutral bus voltage as close as possible to zero.

Key Features

• Compact & Safe: Designed to optimize space while ensuring safety.
• Economical: Cost-effective solution for grounding needs.
• Easy Maintenance: Vertical bus bars simplify servicing, even in double-front panels.
• Reliable Performance: Fully type-tested bus bar system.
• Space-Saving Design: Compact depth for efficient use of switchgear rooms.
• Improved Accessibility: Wider cable alley for easy termination.

HT Automatic Harmonic Power Factor Correction Panel (HT AHPFC)

Our HT AHPFC Indoor Systems utilize high-quality FRAKO / CPSL capacitors and reactors. As a pioneer in advanced power correction solutions, we provide a complete tuned + detuned HT AHPFC scheme in collaboration with FRAKO Germany.

Designed to reduce losses at HT bus and prevent overcompensation, this panel enhances system stability by injecting reactive power in line with network load requirements. The process operates in auto mode using the advanced EMR 9606 AHPFC Relay.

Key Benefits

• Advanced Technology: Uses FRAKO’s state-of-the-art components for optimized power correction.
• Enhanced System Stability: Injects reactive power in auto mode for improved network load handling.
• Customized Solutions: Designed to meet specific client requirements.

Features

• Fully Automated Operations
• Electrical Power Monitoring & Controlling
• Steady Performance with Minimum Maintenance
• Tuned/Detuned/Tapped Harmonic Filter Reactors
• Tuned to 3rd, 5th, 7th, 11th, or 13th Order Harmonics

Generator Circuit Breaker (GCB) Panel

The Generator Circuit Breaker (GCB) compartment provides on-line isolation in the main power circuit between the generator and generator transformer, utilizing either a vacuum or SF6 draw-out circuit breaker. The metal-enclosed switchgear compartment houses both control and protection system components, ensuring reliable operation.

Powergear has also designed mobile cubicles equipped with line-side and neutral-side bus bars, along with the Generator Circuit Breaker and metering/protection equipment. These mobile GCB cubicles are mounted on a trailer, making them ideal for short-term mobile power plants.

Ring Main Unit (RMU)

A Ring Main Unit (RMU) is a fully sealed, gas-insulated compact switchgear unit. It provides a reliable and efficient solution for medium-voltage power distribution. The primary switching devices can be:

• Switch disconnectors
• Fused switch disconnectors
• Circuit breakers

When equipped with a circuit breaker, the RMU also includes protective relaying, which can range from a basic self-powered type to a more advanced version with communication capabilities.
