Introduction

‍

Enhancing the stability of power supply in mission-critical applications, such as data centers or semiconductor fabrication plants, requires the monitoring of switchgears deployed between power utility equipment and electrical equipment. An industry-leading power monitoring system integrator in China chose Moxa’s networking solutions to enable reliable communication between the switchgears and the control center.

Systems Requirmnets

• Collecting large amounts of data from a variety of power monitoring devices and sensors

• The ability to endure high levels of electromagnetic interference (EMI)

Moxa Solution

‍

In the control center, Moxa layer 3 PT-7828* Ethernet switches were deployed to collect a variety of power-related data from field sites and transmit it to SCADA systems. Moxa PT-7528 Ethernet switches were not only used to collect data from Ethernet-based power protection devices but also to enable reliable extensions from the switchgears to the control center through fiber-optic cables. Certified with IEC 61850-3, Moxa Ethernet switches ensured reliable connections against high electromagnetic environments.

‍

Inside the switchgears, numerous serial power meters had to be connected. Moxa MGate MB3660 protocol gateways provided up to 16 serial ports with active Modbus data polling to ensure the fast acquisition of large amounts of data. In addition, Moxa compact ioLogik E1200 remote I/Os provided a variety of digital and analog I/O interfaces, which fit easily into cabinets, for the collection of data from auxiliary contactors and busbar temperature sensors.
