Reading the specification
What these numbers mean for your installation
A datasheet tells you what the unit does. This is what each figure changes about how you specify, feed and site it — worked out for the 100 kVAr specifically, not the range in general.
100 kVAr
100 kVAr of switched capacitance. As a working rule, a plant running at 0.85 power factor needs roughly 0.62 kVAr per kW of load to reach 0.99 — so this bank suits a connected load in the region of 161 kW. Send us a month of billing data and we will size it against your actual demand rather than a rule of thumb.
> 0.95
Most Indian DISCOMs levy a penalty below 0.90 and pay an incentive above 0.95. Holding > 0.95 is usually where the payback sits — pushing closer to unity costs disproportionately more capacitance for a smaller tariff gain, and risks leading power factor at light load.
< 5 seconds per step
Capacitors switch in discrete steps at < 5 seconds per step. That is appropriate for the slowly varying reactive demand of general plant. Rapidly cycling loads — welding sets, large press lines — need a thyristor-switched or hybrid bank instead, or the contactors will wear out prematurely.
Sizing Guide
When is 100 kVAr the right choice?
100 kVAr is the most common panel size for medium-to-large factories where the electricity bill consistently shows a power factor between 0.80 and 0.88. A food processing plant running belt conveyors, pumps, and refrigeration compressors, or a pharmaceutical packaging line with several 15–30 kW servo motors, will typically have a reactive demand in the 80–120 kVAr range. This panel's 8-step switching means the controller can fine-tune compensation to within 12.5 kVAr of the target — precise enough to hold PF above 0.95 across the full production shift without overshooting. If your DG set trips on overload during grid outages, improving PF with this panel will often eliminate the issue without buying a larger DG.
Before you order
Where 100 kVAr goes in, and what the site needs
Typical installations
We supply 100 kVAr most often into medium manufacturing units, industrial facilities, commercial complexes and hospitals with backup power, alongside shopping centers and industrial parks. What separates those sites is how the outgoing ways get allocated. Two boards of this rating can look identical on the schedule and behave completely differently depending on whether one feeder carries most of the load or the demand is spread evenly across them.
Site preparation
At 650 kg you need a pallet truck at minimum and a level, load-spreading base. Check the route for ramp gradients — a hydraulic truck carrying 650 kg will not climb much of one. Leave working clearance on the terminal side for cable entry and inspection. Sustained ambient above 45 °C, or an enclosed room without cross-ventilation, requires derating — send us the room conditions and we will confirm the rating still holds where you intend to put it.
Adjacent ratings
If 100 kVAr is not the right size
Sizing rarely lands exactly on a catalogue rating first time. These are the ratings either side of it in the same range — compare the specification before you commit.
