Springvale Road Streetlighting Trial |
|
|
|
|
|
| A trial of 250watt HPS lamps fitted with the Active Reactor was installed on a major arterial road in Melbourne in August 2004. Figure 1 shows the installation of the luminaires on the poles used in the trial.
|
|
|
|
| Two groups of lamps were installed; the Active Reactor Group containing Active Reactor controllers & the Control Group fitted with standard reactor ballasts. The following are the installation details. |

Site Monitoring |
|
|
|
|
|
Each group of lights is connected to a separate circuit. An electronic power analyser is used in each circuit to measure supply volts, amps, power, power factor, energy & THD. |

Results |
|
|
|
|
The trial has been in operation for over 30 months (10,000+ hours) and the following results have been obtained: |
|
|
|
|
1 |
There has not been a single failure of the Active Reactor during this period. Summer temperatures have been as high as 40 deg Celsius and winter temperatures have been as low as 5 deg Celsius. |
|
|
|
|
2 |
Figure 2 shows the energy savings over the period. A saving of 23% has been realised by the Active Reactor Group compared to the Control Group. |
|
|
|
|
3 |
Figure 3 shows the lamp life extension based on lamp voltage measurements. It is anticipated that lamp life will be extended by 100% for the Active Reactor group compared to the Control Group based on the measurements taken. |

From Graph
Active Reactor lamp has a voltage rise of 1.25V/1000 hours
Standard Ballast lamp has voltage rise of 2.50V/1000 hours
Based on above lamp voltage rises the lamp on the Active Reactor should last approx twice as long as the lamp on the Standard Ballast
