CUSTOMER ACCOUNTS
Consumer Details Other Details
 Account No.
 Consumer No.
 Contract / Connected Load.
 Tariff
 Name of the consumer
 Location address.
Date of installation
Meter No. & Model
No. of Dials
Meter multiply factor
Max Demand Multiplier Factor
Amperes & Volts

6. Fields in the Route sheet which are filled in by Meter Reading Engineer
 Reading date
 Maximum Demand: Demand trend obtained in a month over
successive periods each of 30 min duration.
 Billing Demand: Highest of Max demand recorded in a month
 KWH Reading K-1/ Consumption
 RKVA Reading R-1/ Consumption
 KWH Reading P-1 / Consumption
 RKVA Reading X-1/Consumption
 Sub meter reading / Consumption
 Remarks
 Power Factor: Ratio expressed as a % of Kilowatts Hours to the
Kilovolts ampere hour consumed during the month. In case,
connections where KVA meters do not exist and KVAR meters
are installed, Power Factor shall be the ratio of KWH to square
root of sum of KWH and KVARH.
PF= Case 1 (KWH/KVAH)
PF= Case 2 (KWH)/((KWH)^2+(KVARH)^2)^-1
