Loading Inductor 240V AC Three Phase

Product Code : SCL-EAE-12048

The Loading Inductor 240V AC Three Phase is a stationary electrical testing apparatus used for simulating lagging power factor conditions in low-voltage three-phase networks. Designed for engineering students and technical instructors, this model provides a balanced, variable reactive load to safely analyze transformer regulation, alternator excitation, and power network stability.

Product Description

The Loading Inductor 240V AC Three Phase by Science Lab Supplies provides a precise, highly reliable platform for advanced electrical machinery experiments. This apparatus features a balanced three-phase array of copper wire-wound inductors wrapped around low-loss laminated silicon steel cores. The internal magnetic cores are isolated structurally to reduce eddy current losses and prevent magnetic saturation during prolonged testing under full capacity.

Housed in a heavy-gauge, ventilated sheet steel chassis protected by an anti-corrosive powder coating, this workstation ensures maximum durability under intense institutional use. The front panel houses high-durability selectors or toggle switches that permit balanced step-by-step modifications to the inductive current across all phases simultaneously. This configuration makes it an essential long-term addition for technical institutes upgrading their selection of premium scientific laboratory instruments.

Key Features

• Balanced Three-Phase Reactance: Symmetrical step loading across all three lines maintains system phase equilibrium.
• High-Grade Copper Windings: Premium insulation class copper coils wound on low-loss laminated steel cores extend structural lifespan.
• Multi-Step Incremental Control: Robust front panel switches adjust reactive power consumption smoothly without wiring risks.
• Ventilated Metal Casing: Heavy-gauge, anti-corrosive steel frame uses passive convection vents for thermal regulation.
• Transient Surge Protection: Integrated varistors suppress high-voltage inductive arcs during step transitions under load.
• Insulated Shrouded Terminals: Shrouded 4mm safety sockets ensure absolute user insulation during manual patching.

How to Use the Loading Inductor 240V AC Three Phase

1. Place the load bank enclosure on a flat, level, and well-ventilated laboratory workbench surface.
2. Confirm that all front panel load toggle switches are flipped to their absolute OFF positions prior to 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 properly connected.
4. Energize the primary three-phase supply to 240V AC and sequentially turn on the switch steps to introduce inductive current.
5. Monitor phase parameters using external bench meters to calculate total reactive power consumption with the equation:

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

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

Care & Maintenance

• Dust Elimination: Clean out dust accumulation periodically from the ventilation grilles using dry compressed air.
• Insulation Integrity Check: Routinely audit input terminal sockets for signs of localized heating or loose mechanical joints.
• Storage Environment: Store the unit inside a well-ventilated, dry storage bay to prevent winding oxidation.

Frequently Asked Questions

• Can this inductive load bank be configured in a delta layout?

This standard model is pre-wired internally in a star (wye) configuration; custom delta variants can be ordered upon request.

• 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 ($\cos\theta \approx 0.1$).

• Is the metal chassis frame grounded to protect users?

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

• What happens if a phase experiences an overcurrent event?

The load bank integrates independent branch circuit protection that trips the affected phase line immediately to safeguard the coils.

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

Yes, engineered with high-temperature Class H insulated copper wires, it reliably manages continuous rated loads during prolonged experiments.
