Substation Gateway’s Introduction
NB-IOT Module in Remote meter reading and Street light monitoring

Application of Intelligent electrical measurement and control terminal-HYFW

HYFW is an advanced smart comprehensive monitoring device integrating power monitoring, energy metering management, power quality analysis and electrical safety in one. It can be used in Intelligent Power Distribution System, Energy Consumption Monitoring System, Power Demand Side Management (Power DSM) System and Intelligent Electricity Safety Monitoring and Management System, which is applied in new or retrofit commercial buildings and municipal building and industrial automation fields etc.

How about the product application?

# Electrical Safety

Intelligent acquisition and analysis, electrical safety (overvoltage, undervoltage, overcurrent, overtemperature, residual current alarm, etc.), power monitoring and management, power quality, also with fault diagnosis and analysis functions, accurate discrimination of low voltage Line fault type;

Standard RS485, optional built-in 4G/GPRS/LoRa/LoRaWAN/NB-IoT/P-BUS, meet the networking needs of different power environments, such as LoRaWAN networking mod for prison environment;

Support smoke and flammable gas switch access, support smart device RS485 data access;

Built-in ModbusRTU, MQTT communication protocol, support protocol customized development;

Support remote tripping, resetting, muffling, modifying parameters, upgrading programs, etc.

Select tripping power-off and timing power-off functions;

Local sound and light alarm, 320*240 high resolution large screen LCD display;

Quick response alarm mechanism, the upper limit alarm event priority is higher than the limit alarm event;

Installation with power, which does not affect production, and plug design to improve the installation efficiency;

Electromagnetic compatibility level 4 and above, to prevent hidden dangers.

# Energy Management & Power Demand Side

HYFW realize project electricity and partitions electricity, electrical parameter monitoring, statistics, analysis, and refined power management, energy performance management, and emergency plan management;

Multi-rate metering function realizes peak-cutting valley, and the process adjustment. Demand analysis function realizes power supply transferred to the on-demand from according to the capacity, then to save the cost. It is also possible to predict energy use in the next month and next year, and to plan the management of the use of energy;

HYFW realizes power quality analysis of equipments sensitive to electricity for its voltage/current three-phase unbalance, 2-31 harmonic content, zero-sequence voltage/current, voltage deviation, etc., to ensure safe operation;

Through the analysis of electrical parameters and thermal parameters, the transformer loss and load rate are analyzed, which provides a basis for load transfer. It can analyze the temperature of key power circuits, undervoltage, overvoltage, overcurrent and other warning analysis to achieve safety;

Meet the networking requirements of different power environments, such as wired RS485/wireless LoRaWAN mode for factory/park, 4G/GPRS/NB mode for discrete point;
