Electrical Inductor Load Bank 2.4 kVAR

Product Code : SCL-EAE-12046

The Loading Inductor 2.4KVAR Bank is a variable reactive load bank used for simulating lagging power factor conditions in electrical power systems. Designed for engineering students and laboratory technicians, this apparatus provides adjustable inductive reactance steps to safely analyze alternator regulation, transformer loading, and power factor correction.

Product Description

The Loading Inductor 2.4KVAR Bank by Science Lab Supplies delivers a highly reliable and mathematically precise solution for AC power testing environments. This laboratory testing apparatus features a balanced three-phase array of high-grade copper wire-wound coils wrapped around low-loss laminated silicon steel cores. These internal cores are structurally optimized to eliminate eddy current dissipation and prevent premature magnetic saturation during long-duration experimental procedures.

Enclosed within a heavy-gauge, thoroughly ventilated sheet steel chassis protected by an anti-corrosive powder coating, this workstation provides maximum structural durability under intense institutional use. The intuitive front control interface features heavy-duty toggle switches or rotary step selectors, enabling students to modulate reactive current draw easily without dealing with dangerous unshielded wire setups. This balanced inductive load configuration makes it an essential long-term addition for any technical institute.

Key Features

• Balanced Three-Phase Reactance: Offers symmetrical step loading across all three lines to protect supply circuit equilibrium.
• High-Grade Copper Windings: Utilizes premium insulation class copper coils for localized heat reduction and longer operational life.
• Multi-Step Incremental Selectors: Outfitted with distinct front panel switches for incremental adjustments up to a maximum capacity of 2.4 kVAR.
• Ventilated Casing Architecture: Constructed inside a rugged mild steel frame with safety ventilation slots for natural passive heat dissipation.
• Inductive Transient Suppression: Integrates protective varistor circuitry to absorb high-voltage inductive arcs during load step modifications.
• Insulated Breakout Nodes: Equipped with shrouded 4mm safety sockets to provide absolute user electrical insulation during manual patching.

How to Use the Loading Inductor 2.4KVAR Bank

1. Place the load bank enclosure onto a clear, level, and well-ventilated laboratory floor or workbench space.
2. Confirm that all individual front panel load toggle switches are flipped to their absolute OFF positions prior to attaching any wiring.
3. Wire the incoming three-phase supply lines from your source under test directly to the $L_1$, $L_2$, and $L_3$ safety input sockets, ensuring the neutral terminal is securely grounded.
4. Energize the primary three-phase supply to 415V AC and sequentially turn on the switch steps to introduce inductive current to the system.
5. Track the phase voltage and current indicators using external bench multi-meters to calculate total reactive power consumption using the equation:

$$Q = \sqrt{3} \cdot V_L \cdot I_L \cdot \sin\theta$$

Safety Note: Never disconnect the input patch cords while a load switch step is in the active ON position. Breaking an active inductive loop can generate high-voltage electrical arcing across the terminal nodes.

Care & Maintenance

• Dust Elimination: Periodically inspect the ventilation slots and clean out accumulated dust using dry compressed air or a soft microfiber cloth.
• Insulation Integrity Check: Routinely audit the input terminal sockets for signs of localized heating, discoloration, or loose mechanical joints.
• Storage Environment: Keep the apparatus inside a well-ventilated, dry storage bay free from corrosive moisture or chemical fumes to avoid winding oxidation.

Frequently Asked Questions

• Can this 2.4 kVAR inductor bank be utilized for single-phase loading?

Yes, because the phases are broken out independently on the front terminal panel, you can isolate and utilize a single inducting coil branch for 220V–240V AC single-phase testing applications.

• What is the power factor rating of this inductive apparatus?

The unit functions as a near-pure inductive load bank, maintaining a highly lagging power factor close to zero ($\cos\theta \approx 0.1$) across all switchable steps.

• Is the metal chassis frame grounded to protect users from static leakage?

Yes, the heavy-gauge sheet steel enclosure features a dedicated, low-resistance internal safety grounding line bonded directly to the primary chassis structure.

• What happens if a single phase experiences an overcurrent event?

The load bank is engineered with independent branch circuit protection that trips the affected phase line immediately to safeguard the internal inductor coils.

• Can this unit handle continuous operation during long lab projects?

Yes, because it is engineered with high-temperature Class H insulated copper wires and open-air cooling vents, it reliably manages continuous rated loads during prolonged experiments.
