Presentation transcript:

Reading Hydro Meters S1-3-22 Analyze the electrical energy consumption of a household appliance. Include: calculate consumption using Energuide labels, read hydro meter, interpret monthly hydro bill.

Electricity Production… Electrical power is made at hydro generating stations in Northern Manitoba. The seven sisters hydro dam in northern Manitoba (90km northeast of Winnipeg)

Electricity Production… Water flows through the dam, which turns a turbine, which turns a generator and makes electricity…

Electricity Production… The electricity is transmitted through power lines all across Manitoba.

Determining Your Hydro Bill… Anyone who has electricity at their home, has a main wire connected from the house to these hydro lines. Before the electricity can be used in your home, it must pass through a meter.

Determining Your Hydro Bill… When you turn anything on in your house, current flows through the meter, and turns the dials on the meter. The hydro meter measures how much electrical power you consume, and measures the power in kilowatt hours (kWh) Hydro will send someone to read your meter every other month or so. Sometimes they will estimate your power usage, and other times they will ask you to read the meter, and phone in the reading. There are a number of dials on the meter. Each dial represents a place value (10’s, 100’s, 1000’s, etc.). When we read these dials there are a couple of things we must remember: Check the direction the dial is turning Always read the lower number if the needle is between two numbers.

Determining Your Hydro Bill… To find out how much your power will cost for a month, you must: Take a reading at the beginning of the month. Take another reading at the end of the month. Find the difference between the two readings. (this is how much power you used) Multiply the amount used by the price per kWh.

Determining Your Hydro Bill Example… 1. Read each of the meters below: 2. How many kWh were used during September? 3. If electricity costs six cents per kWh, calculate the billed amount for this customer. Sept 1 September 1st reading = _________ kWh Oct 1 October 1st reading = ________ kWh

Determining Your Hydro Bill Example… 1. Read each of the meters below: 2. How many kWh were used during January? 3. If electricity costs six cents per kWh, calculate the billed amount for this customer. Jan 1 January 1st reading = _________ kWh Feb 1 February 1st reading = ________ kWh
