What is the kVAh formula?

A common approximation is kVAh ≈ kWh ÷ PF. Some tariffs bill on kVAh to account for low power factor increasing apparent energy usage.

What does LT panel mean?

LT (Low Tension) panel is the 415V/240V distribution panel used for breakers, feeders, protection and metering in most commercial and industrial buildings.

What is power factor correction (PFC)?

Power factor correction uses capacitor banks (often in an APFC/PFC panel) to reduce reactive power demand, improving PF and lowering kVA demand and penalties.

What is prepaid metering for PG/co-living?

Prepaid metering in PG/hostel/co-living typically means tenant-level sub-metering plus pay-before-use billing (room-wise recharge) with automated settlement and billing transparency.

What is net metering?

Net metering is a policy where rooftop solar export is adjusted against import in billing, based on local DISCOM rules and settlement periods.

kW ↔ kVA (Power factor)

For three‑phase and single‑phase sizing. Uses \(kW = kVA × PF\).

kVA

PF (0–1)

kW (from kVA × PF)

— kW

kVA (from kW ÷ PF)

— kVA

Notes: PF is typically 0.8–0.99 depending on load mix. For capacitive correction (PFC panels), target PF is often 0.95+ to reduce kVA demand and penalties.

kWh → Bill amount (₹)

“Units” in India usually means kWh. This is a quick estimate (excluding fixed charges/taxes).

Energy (kWh / units)

For prepaid / sub‑meter billing (PG, hostel, co‑living), most operators bill “per unit” and may add fixed/common‑area allocation separately.

kWh ↔ kVAh (approx)

Many commercial connections bill on kVAh. Approx: \(kVAh ≈ kWh ÷ PF\).

kVArh (rough)

— kVArh

kVArh is shown as a rough reference using PF → angle conversion; actual billing differs by DISCOM and meter class.

DG fuel efficiency (kWh/L)

Compute “units produced per litre” from measured load \(kW\) and diesel consumption \(L/h\).

Load (kW)

Diesel consumption (L/h)

Units per litre

— kWh/L

Litres per unit

— L/kWh

Tip: capture at multiple loads (25%, 50%, 75%) to see efficiency curve; low-load DG runs are usually inefficient.
