Week 4 Update - C505 and C305 Power Monitoring and Fixture Counting

Hello

The first thing I did today was calculate the total power consumed in C505. Like last week I found the source of the power which was an outlet in which all the powers bars were connected to. In C505 we have computer benches like in C527, as well as, a wall containing our lab projects like DSC alarm panels, electrical wiring, and smart switch panels.  Like last week I connected everything to the power bars and all the power bars to the source outlet. I plugged in the Electricity Meter and took a reading of 461 Watts.  After I took the meter I found out that all the computer on the bench went out. I thought the bench and the wall were separate, turn out I was wrong. I think I'll do this again next week with the help of one of my professor's to take an accurate reading. 

After that, I got a different Light Meter from one of my professor's and took lux readings around C505 again. Here are the lux readings from the 9 points:

• Point 1 = 947 Lux
• Point 2 = 802 Lux
• Point 3 = 635 Lux
• Point 4 = 557 Lux
• Point 5 = 515 Lux
• Point 6 = 344 Lux
• Point 7 = 519 Lux
• Point 8 = 467 Lux
• Point 9 = 463 Lux
• Average = 421.75 Lux

These readings are different that the ones I too last week because there is more of them and I took the readings by placing the light meter on the desk rather than on a cart in the corners of the room. Also since I used a different light meter, this one could be calibrated differently than the other one.

Afterwards, I was told I should figure out constantly monitor the power in a room.  I researched power monitors found a get one, but it was expensive. Anyway, my professor gave me a power monitor, but he wanted it to get permanently fixed to the Circuit Breaker in C505 so he suggested to use a CT (Current Transformer). I'll look into this next week,but I included a photo of the power monitor my professor gave me.

Next, I took the Electricity Meter and went to C305 and calculated the total power being consumed. From the source I got a reading of 1.1 Watts then I multiplied it by the 20 benches to get 22 Watts. The reason the Watts is so low is because only the two computers are on and not the electro-pneumatic and PLC stations. Next week, I plan to go back to get the true calculation. 

For the number of fixtures, there were 6 fixtures in 1 row which I multiplied by the 7 which the total number of rows. I also added in the 4 fixtures in the back to get a total number of 46 fixtures. 

For the total number of lamps, there were 2 lamps per fixture so I multiplied 2 by 6 to get 12 and then multiplied 12 by 7 and added in the 4 lamps in the back to get 88 lamps in total.
