Chapter 1 Introduction
Overview
Paradigm Shift in Energy Management
When energy costs were low, energy management mainly focused on controlling the total energy
supply to all loads using switchgear panels, including incoming feeders and ABS panels for stable
power supply. However, carbon pricing policies have been implemented since 2015, and energy costs
have sharply increased. This has resulted in a rapidly growing need to manage energy usage on
individual branch loads in distribution panels at various industrial facilities, manufacturing plants, IDC
centers, etc.
Limit in Applying Digital Power Meters Used in Switchgear Panels to Distribution Panels
Installing digital power meters used in existing switchgear panels at distribution panels entails
limitations, such as narrow installation space, electrical hazards arising from the voltage and current
wiring process, and high installation costs. It makes it difficult for energy managers to access energy
data on individual branch loads and devise practical energy efficiency measures for each branch load.
Power Meters Specialized for Managing Major Branch Loads
The distribution panel digital power meter product line includes Accura 2300S installed on the front of
distribution panels(including MCC panels) and Accura 2350 installed at individual branch loads inside
distribution panels. Accura 2300S collects power data from multiple Accura 2350 modules via internal
communication and displays measurement data on each branch load. This enables energy managers to
check power data on individual branch loads in distribution panels, which were unavailable with the
existing digital power meters installed at switchgear panels.
Accura 2350-1P3FSC Module Suitable for Measurements at Distribution Panels in Data
Centers with Multiple Single-phase Feeders
Distribution panels within data centers have multiple single-phase feeders with the same current ratings
for power supply to servers. As the basic module, Accura 2350-1P3FSC performs measurements in three
single-phase feeders with the same current ratings at the same time. Compared to installing Accura
2350-1P/1PSC module on each feeder, it drastically saves installation time and costs.
