What Does imp/kWh Mean on an Electricity Meter?
Read the pulse constant on your meter, understand what each flash measures, and turn timed pulses into an estimate of average power.

How an Electricity Meter Turns Energy Use into LED Pulses
A practical explanation of voltage and current measurement, energy accumulation, and the pulse constant printed on a digital meter.
Single-Phase vs Three-Phase Electricity Meters
Understand the supply labels, total-energy readings, and why your meter constant matters more than a guessed supply type for pulse calculations.
How to Estimate an Appliance’s Electricity Consumption
Compare baseline and appliance-on readings, account for cycling, and estimate kWh without treating nameplate watts as a measured result.
How Inverters Affect Electricity Meter Readings
Separate backup battery charging, inverter appliance operation, and rooftop solar import/export before interpreting your meter.
Prepaid and Smart Electricity Meters: What Changes?
Understand payment mode, remote readings, displayed energy, and the limits of comparing an app balance with a kWh register.
How to Investigate a Higher Electricity Bill at Home
Check billing periods, compare kWh, and use repeatable measurements to investigate a change without guessing or touching electrical wiring.
How to Calculate an Electricity Bill from Meter Readings
Work out units used, apply your actual tariff, and separate energy charges from the rest of the bill.
