14 Watt Incandescent Bulb Testing
We are testing a 14 Watt Incandescent Bulb at 220 Volts Mains AC input. We are using Embuilt SPEA-1 to test the Bulb properties.
Specifications:
230 Volts, 14 Watt

Test Results
When power is on the following results are found:
- Vrms: 221.3 Volts
- Arms: 63.58mA
- Watt: 14.07Watt
- VTHD%: 2.7%
- ATHD%: 2.8%
- V3rd Harmonics Value: 4.921 Volts
Analysis: Here we can see that VTHD is 2.7% which means Input Supply has 2.7% distortion in Voltage.
ATHD % is 2.8%. Here question is if bulb is resistive so why there is Amps THD.
Answer: ATHD is sum of VTHD and Distortion caused by load. So NET THD is 0.1%.
3rd harmonics of Voltage is 6.329 Volts.
Voltage Harmonics in % for 14 Watt Incandescent Bulb by SPEA-1
Here we can see the 3rd harmonics of voltage in % of first harmonics. 3rd Voltage harmonics is 2.1% of Vrms Harmonics.
Note: Here we note that ideally first harmonics is to be equal of Vrms and other order harmonics are to 0.
3rd Harmonics Value of Current by SPEA-1
Here we can see the 3rd harmonics Value of Amps. It is 0.985mA.
3rd Harmonics % of Current for 14 W Incandescent Bulb by SPEA-1
In the above image 3rd Harmonics of Amps shows in display 6. It is 1.6% of Arms (63.77mA).
Other parameters can also be seen on SPEA-1.
