What does ZSM in the distribution box represent
ZSM service aka management service: A set of offered management capabilities. Management function: Logical entity playing the roles of service consumer and/or service producer. This shift is largely influenced by the ZSM (Zero-touch network and Service Management) Framework created by ETSI, which lays out a reference architecture for fully automated service management across various domains. The ZSM Framework Reference Architecture makes it possible for multi-domain. Zone-selective interlocking (ZSI), also called zone restraint, is a system designed to reduce the stress on electrical distribution equipment during short-circuit or ground-fault conditions. It allows an upstream breaker to trip instantaneously on a fault in its zone while maintaining coordination with downstream breakers. The attached data. Check whether a ZSI IN signal from the downstream Q3 is present? No ZSI IN signal present! The tripping operation occurs with the time tZSI = 50 ms A ZSI IN signal from Q3 detected.
