Multi-load Metering -Reducing energy consumption in buildings
Multi-load metering is one of the good solutions for
Medium Voltage Switchgear Metering
Medium voltage switchgear metering refers to a solution or practice that integrates power metering, power quality monitoring, and other electrical parameter measurement functions into the MV switchgear.
It is not just a simple placement of an electric meter next to the MV switchgear. Still, the metering instrument (such as a smart meter, multi-function meter, power quality analyzer, etc.) is used as an integral part of the MV switchgear and closely cooperates with core power equipment, including circuit breakers, disconnectors, busbars, and protection relays. This article will mainly introduce the types of meters in medium voltage switchgear.

Blue Jay can provide switchgear metering solutions: Basic panel meters, Basic energy meters, Basic panel meters, Advanced meters.
Basic panel meters
As for basic panel meters, we mainly provide Ammeters(AMP) and Voltmeters (VLT) for medium voltage switchgears. These basic panel meters are mainly used to measuring current or voltage.

Basic energy meters
Our foundational energy meters are designed for MV switchgear requiring measurement of current (I), voltage (U), frequency (F), active power (P), reactive power (Q), apparent power (S), power factor (PF), TOU, and energy. These energy meters also feature integrated energy alarm (Ealarm) and input/output (I/O) capabilities.
This type of basic energy meters is instrumental in medium voltage (MV) switchgear environments, providing essential data for energy management systems. Its functionalities include granular energy statistics for individual branches and overall incoming lines, detailed time-of-use (ToU) metering across peak, valley, and flat periods, and crucial bidirectional measurement for photovoltaic (PV) and energy storage grid integration points. This comprehensive data empowers MV switchgear users to streamline energy cost allocation, quantify energy conservation efforts, substantiate billing, and conduct foundational load analysis.

Basic Panel Meter
Basic panel meters have metering and sub-metering functions for medium-voltage switchgear. In addition to providing all the fundamental energy meter functions, these panel meters are equipped with advanced features such as minimum/maximum recording, harmonics analysis, unbalance monitoring, THD, demand tracking, and an integrated clock/calendar.
For industrial and commercial users who have certain management needs for power data, this type of meter can improve the precision of energy management, optimize demand management, extend equipment life, and warn of phase-to-phase faults through imbalance.

Advanced meters
Our advanced meters for MV switchgear go beyond basic panel metering, offering comprehensive functionalities such as power quality monitoring, flicker, transient detection, and sag/swell analysis. This type of meter is mainly used for critical loads with extremely high power quality requirements (data centers, hospitals, precision manufacturing), sensitive equipment that is susceptible to grid disturbances, and occasions where fault analysis and responsibility determination are required. For example, determine the frequency and magnitude of voltage sags/swells, transients, and flicker events.
