Why transition to a digital substation?

Reasons abound, including: increased safety, interoperability, ease of configuration, maximized reliability and availability, real-time awareness, smart grid communications capabilities and reduced cost of ownership.

Digital substation: addressing your cybersecurity fears

Education is paramount in enacting cybersecurity. This webinar builds awareness of requirements to secure substation automation protection and control systems and utility enterprise interfaces.

Introduction to protection & control

Better understand power system protective relaying with this overview of key concepts, protective relay classifications, operating principles and relaying philosophy, with a brief terminology review.

Fundamentals of communication for protection

This webinar gives protection engineers a foundation in communications to formulate protection-imposed requirements for communication engineers and work jointly on their implementation.

Wireless communication fundamentals for electric utility applications

Communications are key to smart grid plans. Using proprietary narrowband networks for each application is impractical. This webinar explains why and what is needed.

Input sources for protective relays

A relay is only as good as its analog input. Gain knowledge of analog conventional voltage and current instrument transformers, transient response and stray flux.

Line protection fundamentals

This introduction details basic principles of line distance relaying such as operating characteristics, fault loops, faulty phase identification and more.

Transformer protection fundamentals

This webinar discusses challenges of protecting transformers with digital relays covering fundamental theory regarding transformers, harmonic restraint, differential protection and backup overcurrent protection.

Microgrid design concepts & key considerations

This overview of core microgrid design focuses on grid-tied microgrids exploring asset mix, generation and storage sizing, grid connection and transition, and fundamental economics.

Generator protection fundamentals

Generator protection schemes are unique in many ways. This webinar addresses the basics of generator protection principles and the dynamics of synchronous generators.

Busbar protection fundamentals

Bus protection schemes must recognize current transformer saturation and refrain from operating for external faults while operating quickly for internal faults. Learn about unique considerations.

Enabling protection applications with MPLS networks

Gain insight into the groundbreaking technology that Hitachi Energy has pioneered to reliably and securely transition teleprotection from SONET to MPLS-TP.

Wide area monitoring, control & protection using synchrophasor measurements

Learn the basics of synchrophasor measurements in power systems. Discussion covers functions, requirements and operation of phasor measurement units (PMUs) and phasor data concentrators (PDCs).
