Imp/kWh is short for Impressions per kWh (unit) of electricity which passes through the meter where one 'impression' is a brief flash of an LED. For example, if the LED flashes once every 5.2 seconds on a meter labelled 800 kWh, the power going through the meter at that time will be 3600 / (5.2 * 800) = 0.865 kW.
How do you calculate maximum demand? General Formula to calculate the Maximum Demand is described below: Maximum Demand= Connected Load * Load Factor / Power Factor. Where, Connected Load = Total Connected load in the facility in kW.
what is IMP kWh?Imp/kWh is short for Impressions per kWh (unit) of electricity which passes through the meter where one 'impression' is a brief flash of an LED. The majority of meters are labelled 1000 Imp/kWh which means that the LED will flash 1000 times for each kWh of electricty which passes through.
What is maximum demand in energy meter? MAXIMUM DEMAND METER. Description : Maximum Demand meter is used for monitoring thermal loading in Power Distribution systems, Networks, Machines etc. It indicates maximum loading current over a period. In the Maximum Demand meter the measuring current flows through the bimetal spiral which is temperature sensitive.

How do you calculate a single phase energy meter constant? Determine watt-hours of energy used in the timed period by multiplying the meter constant by the disk revolutions for that period. We will assume the meter constant to be 7.2 (Kh = 7.2). 5. Divide the minutes in the timed period into 60 minutes to determine how many such periods there are in an hour.
