ECOD electric energy saving device

at Lion Company Bangkok, Thailand

• Objective – To achieve BKK electrical energy saving at

least 8% • Problem Statement – Energy saving is a persistent strategy of Lion

Thailand to enhance competitiveness and environmental conservation.

– Metropolitan Electrical Authority will increase FT charges in May, 2017 hence electricity cost per unit will increase.

• Method Installation of a suitable electric energy saving device

– ECOD Smart Optimizer is an electric power saving device which: • Controls the voltage and current in the optimum range

• Filters harmonics and increases power factor

• Balances the phase voltage

• Prevents trouble shooting (sudden voltage drop or surge)

• Improves quality of electrical power supply in overall.

Working Principle: Electronic controller

regulates the direction of the current in

the coil of each transformer (one per

phase) to regulate and balance the

network parameter to sustain within it

highest performance whilst minimizing

power loss.
