ELECTRICAL ENERGY METERS

 
With the launch of our latest devices- 0.2Class Load Manager, and 0.2Class Energy Master, we have reached to a place next to perfection, not only in terms of accuracy and reliability, but also in terms of providing best cost-effective solution, for the same Class of Accuracy.
With an inbuilt valve-positioner unit in our PIDs, we eliminate the need of unnecessary complication, and expansion of the system, hence reducing the overall cost.
 
 

Model - Energy Master

 

ENERGY MASTER series Multifunction Meters, Trivector Meters and Load Managers
Lectrotek manufactures ENERGY MASTER-series Multifunction Meters, Trivector Meters and Load Managers as per Class 0.2S and 0.5S of IEC-687 standard. The meters provide information of over 35 AC parameters, including instantaneous readings of phase-wise current, voltage, active/reactive/apparent power, Power Factor, Demand etc. as well as billing in terms of Active (Wh), Reactive (VARh) and Apparent (VAh) stored in monthly and cumulative energy registers.

Energy Master is available with following functions
Basic Model ; Trivector Meter / Multifunction Meter (Class 0.5 / 0.2 IEC 687)
With Energy Audit function with 35-day energy data logs as per CEA/MEA norms.
Load Manager functions with 6 relays outputs

Model - ENERGY MANAGEMENT SYSTEM EMS-SCADA

 
 

ENERGY MANAGEMENT SYSTEM EMS-SCADA using Energy master-series Multifunction Meters.

EMS-SCADA System using Energy master-series Multifunction Meters.

ENERGY MASTER-series Multifunction Meters/ Trivector Meters/Load Managers can be used in stand-alone mode as well as part of RS-485 port connected Energy Management System EMS-SCADA.

The EMS-SCADA provides easy to handle Window-based functionality and provides information on electrical loads for individual, machine-wise, sub-station, transformer etc. GUI shows Singlel Line diagram (SLD), Energy Balance, Plant-wise consumptions, and daily/weekly/monthly graphs & reports of load fluctuations etc. Load management functions of voltage, curremt, frequency, VA demand, PF etc. monitoring and tripping are carried out through individual load relays in the Energy Master, and /or PLC-based tripping, under supervisory control from EMS-SCADA. Modbus-RTU communication makes communication with other vendor software easy.
