Precision 3 kVAR Capacitor Bank

Product Code : SCL-EAE-11176

The Precision 3 kVAR Capacitor Bank is an electrical laboratory apparatus used to apply controlled capacitive reactive loading for AC circuit study, leading power factor demonstration, reactive power observation, and electrical machine training. It is suitable for engineering colleges, polytechnics, ITI/TVET centres, electrical training labs, distributors, and institutional procurement buyers.

Product Description

The Precision 3 kVAR Capacitor Bank from Lab Equipments Ambala is best positioned under Physics Lab / Electrical and Electronics / Electrical Machine Training Apparatus. A dedicated product page with final product code, voltage rating, phase type, current rating, capacitance steps, switching arrangement, enclosure, protection, discharge system, and duty cycle should be confirmed before publishing.

A capacitor bank provides reactive AC loading by using capacitor sections connected in a controlled arrangement. In laboratory use, a 3 kVAR capacitor bank helps students observe leading power factor, phase lead, reactive current, voltage-current relationship, and power-factor correction principles when used with approved AC sources and suitable measuring instruments.

Key Features

• 3 kVAR capacitive rating: product name indicates 3 kVAR reactive-load capacity; final continuous or intermittent duty rating should be confirmed.
• Capacitive load operation: supports AC experiments where current leads voltage because of capacitance.
• Power factor training: useful for demonstrating leading power factor and reactive power behaviour.
• Electrical machine use: suitable for alternator, transformer, and AC source experiments when correctly rated.
• Step or bank-based loading: may include switched capacitor sections; confirm final capacitance configuration before publishing.
• Measurement-compatible setup: can be used with voltmeters, ammeters, wattmeters, power factor meters, and power analyzers.
• Specifications pending: voltage, phase, current, capacitance steps, discharge method, protection, enclosure, and duty cycle must be verified.

How to Use the Precision 3 kVAR Capacitor Bank

1. Place the capacitor bank on a dry, stable, ventilated laboratory bench or floor stand.
2. Confirm voltage rating, phase type, current rating, 3 kVAR load rating, duty cycle, and earthing requirement before connection.
3. Connect the unit to the AC source, alternator, transformer, or trainer according to the approved wiring diagram.
4. Connect suitable instruments such as voltmeter, ammeter, wattmeter, power factor meter, frequency meter, or power analyzer.
5. Set the capacitor load control to the minimum or safest starting position before energising the circuit.
6. Switch on the supply and add capacitive load gradually using the approved switches or steps.
7. Record voltage, current, real power, apparent power, reactive power, power factor, frequency, and phase-lead observations.
8. Switch off the supply, discharge the capacitors according to the manual, and confirm safe voltage before disconnection or storage.

Safety note: Use the Precision 3 kVAR Capacitor Bank only within its confirmed voltage, current, phase, kVAR, and duty ratings. Capacitors can retain charge after power is removed; use trained supervision, proper earthing, insulated leads, approved discharge procedure, protective switching, and verified zero-voltage checks before handling terminals.

Care & Maintenance

• Keep capacitor sections, terminals, switches, vents, indicators, and enclosure surfaces clean and dry.
• Inspect insulation, earthing continuity, terminal tightness, capacitor bulging, leakage, overheating marks, and discharge circuit condition before operation.
• Do not exceed the confirmed kVAR rating, voltage rating, current rating, phase rating, capacitance-step rating, or duty cycle.
• Store the capacitor bank in a dry, dust-controlled area away from moisture, corrosive fumes, heat sources, and mechanical impact.

Frequently Asked Questions

What is a Precision 3 kVAR Capacitor Bank used for?

A Precision 3 kVAR Capacitor Bank is used to apply capacitive reactive load for AC circuit experiments, leading power factor study, power-factor correction demonstrations, and electrical machine training.

Is the 3 kVAR rating confirmed?

The product name states 3 kVAR. The final voltage, phase type, current rating, capacitance steps, duty cycle, and protection details should be confirmed before publishing.

Is this a capacitive load or an inductive load?

This product name indicates a capacitive load. A capacitive load stores energy in an electric field and causes current to lead voltage in an AC circuit.

Can this capacitor bank be used for power factor correction experiments?

Yes. A suitable capacitor bank can demonstrate leading power factor and power-factor correction principles when used with approved meters, AC sources, and compatible inductive-load equipment.

What instruments are used with this capacitor bank?

Common supporting instruments include voltmeter, ammeter, wattmeter, power factor meter, frequency meter, power analyzer, and the AC source or electrical machine under test.

Can students touch the terminals after switching off?

No. Capacitors can retain charge after power is removed. Students should not touch terminals until capacitors are discharged according to the manual and safe voltage is confirmed by trained staff.
