ENERTEK Intelligent Power
Saving Streetlight:A New Energy-saving Technology for Road
Lighting
ENERTEK Reflector
ENERTEK intelligent street light system adopts innovative
technology. Its reflector of accurate positioning and multiple
facets mirror surface can remarkably raise the luminous efficacy.
ENERTEK Streetlight of automatic street light control has
much better performance than common streetlight in the
utilization of light ray, comprehensive luminous efficacy, ands
power density.

Apparent power at Each Side of Transformer |
*4***0* (1*0.*7)÷0.*5 =*7.*5 KVA |
0.*7 is the percentage of consumed power of inductive ballast; 0.*5 is power factor |
*4***0*(1*0.*4) ÷0.*9=*5.*4 KVA |
0.*4 is the percentage of consumed power of inductive ballast; 0.*9 is power factor |
Load Torque |
*7.*5***0* 0.5*1.1*1.*5 =****1 KVAM |
0.5 is uniformly distributed load; 1.1 is coefficient of zero line current of three phase imbalance; 1.*5 is coefficient of reserved length of cable |
*5.*4****5*0.5* 1.1*1.*5 =****7 KVAM |
0.5 is uniformly distributed load;1.1 is coefficient of zero line current of three phase imbalance; 1.*5 is coefficient of reserved length of cable |
Percentage of Voltage Loss at Tail End |
