Maximizing Reliability by Testing Critical Elements in the Protection System

Out-of-step protection is a critical component of modern power system protection schemes—its importance has grown significantly with the increasing penetration of inverter-based resources (IBRs) and their impact on system impedance and inertia. To help engineers and technicians navigate these complexities, the Maximizing Reliability by Testing Critical Elements in the Protection System eBook offers a practical yet comprehensive guide to testing these essential components.

This eBook on Maximizing Reliability by Testing Critical Elements in the Protection System is part of an eBook series on Maximizing Electrical Power Reliability. The articles presented are a collaborative effort between NETA -The InterNational Electrical Testing Association and Megger.

Megger has been designing and making test and measurement instruments for over 120 years. Their instruments perform electrical measurements for preventative maintenance, troubleshooting, and commissioning across seven core application segments: transformer test, cable test and diagnostics, protection relays and systems, circuit breakers, and diagnostics, low-voltage installations, general electrical testing, and motor and generator testing.

For nearly 50 years, NETA’s Standard for Maintenance Testing Specifications for Electrical Power Equipment and Systems (ANSI/NETA MTS) has provided the electrical power industry with guidance for maintaining critical electrical infrastructures. For ANSI/NETA maintenance testing specifications on Transformers refer to section 7.2.1.1 – 7.2.2 in the ANSI/NETA MTS 2023 edition.
