Improve Facility Efficiency with Energy Monitoring Systems

Energy costs represent one of the largest expense items for many industrial facilities. Systematic energy monitoring is the first and most critical step toward reducing these costs.

Fundamentals of Energy Monitoring

An effective energy monitoring system must continuously and accurately measure the following data:

• ▸Active power (kW) and energy consumption (kWh)
• ▸Reactive power (kVAR) and power factor
• ▸Voltage and current values (separately for each phase)
• ▸Frequency and total harmonic distortion (THD)
• ▸Demand peak (maximum power demand)

Demand Peak Management

Energy distribution companies use demand peak in addition to consumption volume for billing. By identifying peak periods with a monitoring system, loads can be managed using time-shifting or staged commissioning.

Caselen EMA Series

EMA series energy analyzers measure all of the above parameters in real time. With the built-in Modbus RTU/TCP interface, they easily integrate with SCADA and energy management software. Historical data recording allows monthly or annual energy reports to be generated.

Integration with Protocol Converters

Protocol converters like the Caselen CE2S can be used to connect meters and relays of different brands and protocols to a single platform. These devices perform bidirectional translation between Modbus, DNP3, and IEC 61850, making it easy to integrate existing infrastructure into modern energy management systems.
