7 MAN MACHINE INTERFACE
7.1 Overview
HMI is known as the Human Machine Interface. HMI is the main communication interface between
the control system and the operator. The friendly LCD facilitates the operator, providing all
operating system information in the screen of the front display panel, including binary inputs or
outputs, circuit breakers status, version of operating system program, alarm signals, tripping
operation, disturbance records, and signal of measuring quantities (voltage, current and angle)
etc., Besides these, it’s also useful for modifying the operating system configuration settings and
protection function settings as well. The HMI can also be helpful during commissioning work.
Additionally, the PRS IED studio software helps to conduct all above listed function through
communication port (Ethernet cable) on the PC or laptop.
