Auto PFI Panel — Power Factor Improvement in Bangladesh

A poor power factor is one of the most common — and most avoidable — causes of high electricity bills in Bangladeshi industry. When your power factor falls below the utility threshold (typically 0.90 for BPDB commercial connections), you are billed for reactive power demand that your equipment draws but does not convert into useful work. Meghna Power's Automatic Power Factor Improvement (Auto PFI) panels continuously monitor your load and switch capacitor banks in and out to maintain a target power factor of 0.95 or higher — automatically, without operator intervention.

Our Auto PFI panels are built around proven automatic power factor relays driving thyristor or contactor-switched capacitor banks sized to your load profile. We design each panel to your specific contract demand and measured reactive power requirement, so you are not paying for more capacitance than you need. The result is a lower maximum demand reading, reduced kVAr charges on your electricity bill, and less heat in your cables, switchgear, and transformer — extending equipment life across your whole installation.

Panels are manufactured in our Narsingdi workshop, housed in powder-coated mild-steel enclosures with IP42 or IP54 protection, and delivered pre-wired and factory-tested. Our team can handle complete installation including CT wiring, commissioning of the power factor relay, and verification of power factor improvement against your recent utility bills.

APPLICATIONS

Textile & Spinning Mills

Large motor loads in weaving and spinning create significant reactive demand. PFI panels bring factory power factor within BPDB billing thresholds.

Cold Storage & Refrigeration

Compressor motors are heavy inductive loads. Automatic step switching keeps PF above 0.95 even as compressor duty cycles vary.

Garment Factories

Mixed loads across cutting, sewing, and finishing floors result in a varying power factor. Auto PFI panels handle this variation in real time.

Commercial Buildings

Shopping centres, office towers, and hotels benefit from PFI where chiller and lift motor loads pull power factor below utility requirements.

Steel & Foundry Plants

Arc furnaces and induction heating create large reactive current spikes. Fast-switching thyristor PFI panels control reactive demand effectively.

Pumping Stations

Water treatment and irrigation pump stations running multiple induction motors benefit from centralised reactive compensation.

FREQUENTLY ASKED QUESTIONS

Q

How much can I save on my electricity bill?

Savings depend on your current power factor and utility tariff. Industries moving from a power factor of 0.75 to 0.98 typically see maximum demand charges fall by 20–30%, with additional savings from reduced I²R losses in their distribution system. We can estimate your specific savings from your last three utility bills.

Q

What is the difference between contactor-switched and thyristor-switched panels?

Contactor switching is lower cost and suitable for most industrial loads. Thyristor (solid-state) switching is faster and transient-free, making it appropriate for loads with rapid power factor fluctuations such as arc furnaces or variable-speed drives.

Q

Will a PFI panel cause problems with my variable frequency drives?

Standard fixed capacitor banks can interact badly with VFDs, but our auto PFI panels are designed with detuning reactors (typically 7% or 14%) when VFDs or other harmonic-generating loads are present. This prevents resonance and capacitor overload.

Q

How long does installation take?

For a standard industrial installation, our team can complete wiring, commissioning, and power factor verification in one working day. Larger multi-panel installations may take 2–3 days. We work around your production schedule where possible.
