Industrial electrical power users often have to pay a maximum demand charge in addition to usual charge for the number of units consumed. This charge is usually based on highest amount of power used during some period during the metering month. The maximum demand charge often represents a large portion of the total bill & may be based on only one isolated 30 min. episode of high power use. Monitoring power use & turning off or reducing nonessential loads during such periods of high power use can realize considerable savings. The maximum demand controller is a realistically priced stand alone controller suitable for small to medium consumers wishing to reduce their Maximum Demand in an economical & simple manner.
Applications:
*Actual Demand in usage is closed to the contracted demand.
*The actual maximum demand can be reduced, saving considerable Electricity charges.
*A positive method to ensure that Maximum Demand never exceeds the contracted demands.
*When actual demand in use & contracted demand are close, M.D. Controller avoids risk of crossing the limits & penalties & disconnection.
*Maximum utilization of demand results in saving the pay back period.
Why the Demand Monitoring is necessary:
*To keep the minimum cost per unit of utilized,the maximum demand reached should be minimum.
*Vigilant Monitoring helps tp keep the demand within the limit prescribed by the electricity authorities & so avoids disconnection.
*Helps to maintain power factor. For a fixed load,the power factor must be fixed one. If demand varies due to voltage variations or failure of capacitor banks, demand monitoring gives the indication & avoids penalty on low power factor.
