Industrial
electrical power users often have to pay a maximum demand charge in
addition to usual charge for the number of units cinsumed. This
charge is ususlly based on highest amount of power used during some
period during the metering month.aaaathe 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 & turing 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 ruduce
their MAximum Demand in an economical & simple
maner. Applications:
- Actual Demand in usage is closed to the
contracted demand.
- The actual maximum dmand can be reduced,
saving considerable Electricty 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.
