Terminology

Voltage – Volts (V) Current – Amps (A) Resistance – Ohms

(R) Power – Watts (W) Ohms Law kW – kilowatt kWh – kilowatt hour Power Factor Load Factor

kVA – kilovolt ampere

rkVA – reactive kilovolt ampere

CDD – Cooling Degree Day

HDD – Heating Degree Day

On-Peak Hours Off-Peak Hours


Power

P (watts) = V (volts) x A (amps)

A (amps) = P (watts) / V (volts)


KW

•W (watt) x 1,000 = KW (kilowatt)

•Demand

•Rate at which energy is used

•W = V x A


KWH

•KW (kilowatt) x Time (hours) = KWH (kilowatt – hour)

•Energy consumed during a period of time


Distribution

Typical voltage: 13.2 kV, 34.5 kV

Overhead vs. Underground

Right of Way/Easements

Tree Trimming Storms Vehicle Accidents Safety


Service Types

Overhead Underground


Metering

Electric Meter, or Watt-hour Meter, an instrument that measures the amount of electric energy used by a consumer.

The meter is calibrated in kilowatt-hours. One kilowatt-hour is the amount of

electric energy required to provide 1,000 watts of power for a period of one hour.

Ten 100-watt light bulbs left on for one hour consume one kilowatt-hour of electric energy.


Analog Meters

Five dials The basic unit of

measure of electric power is the watt.

One thousand watts are called a kilowatt.

If you use one thousand watts of power in one hour you have used a kilowatt-hour (kWh).


Digital Meters

Digital readout Meter automatically

scrolls through several different displays.

Each display remains on screen for three to five seconds.

These displays will show your kilowatt-hour usage, date and time and other network and diagnostic information
