Loading Inductor 2.5KVAR Bank
Product Code : SCL-PLE-11829
The StemAids 2.5kVAR Loading Inductor Bank is an industrial-grade reactive load workstation engineered for the empirical study of AC power systems, lagging power factor, and magnetic reactance. Capable of providing up to 2.5 Kilovolt-Ampere Reactive (kVAR) of inductive load, this apparatus allows students to simulate the electrical characteristics of high-power industrial motors and transformers. Manufactured to ISO 9001:2015 standards, it is a critical component for Electrical Engineering laboratories focusing on power quality, circuit resonance, and power factor correction.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Reactive Interface: Facilitates student understanding of Inductive Reactance (XL) and how it opposes AC flow without dissipating "real" power as heat, supporting Power Systems Module 201.
- Power Factor Quantification: Enables the physical study of lagging loads; learners apply the inductor bank to observe how current waveforms "lag" behind voltage waveforms.
- Correction Analysis: Supports the analysis of load compensation; students evaluate how adding a parallel capacitor bank can counteract the 2.5kVAR inductive load to achieve unity power factor.
- Network Evaluation: Allows students to evaluate voltage drop and the increase in apparent power (kVA) when inductive loads are introduced to a distribution system.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant). Due to the high density of the copper and steel, units are secured with internal bracing to prevent mechanical damage to the core or switches during maritime transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a factory test report specifying the precise inductance (L) for each step.
- Durability: Tropicalized design featuring Vacuum Pressure Impregnated (VPI) varnish on all coils to prevent moisture ingress and minimize acoustic noise (humming) in humid environments.
Direct OEM Sourcing Advantages
Procuring the StemAids 2.5kVAR Loading Inductor Bank directly ensures vertical manufacturing control:
- High-Efficiency Core Design: We use premium-grade laminations to minimize hysteresis and eddy current losses, ensuring the load behaves as a nearly pure inductor.
- Precision Step Matching: Direct oversight of the coil-winding process ensures that each toggle switch provides the exact rated VAR at nominal line frequency (50/60Hz).
- Direct Factory Spares Availability: Guaranteed availability of replacement industrial toggle switches, terminal assemblies, and internal fuses to maximize the long-term ROI.
- Manufacturing Control: Direct oversight of dielectric strength and earth-leakage testing ensures the highest level of operator safety during high-current AC experiments.
