General types of load tap changer (LTC) mechanisms, breathing configurations, and electrical designs, described for reference for determining methods of testing and evaluating dissolved gases in mineral-based transformer oils in…
This guide is intended to provide to the specification writer the information to prepare a specification for the purchase of an excitation system. This guide is presented in narrative form…
Test methods and preferred values for metal-oxide varistor (MOV) surge protective components are covered in this standard and have the following main parameter ranges: packaging (leaded disc-type or surface mount),…
Standardization of circuit integrity cable testing is beneficial to cable manufacturers, distributors, and users. Uniform procedures, consistent, repeatable results, and measurable test acceptance criteria are required to allow comparisons among…
New tests added to IEEE Std C62.11TM-2012: a switching surge energy capability test (thermal energy rating), a repetitive single-impulse withstand capability test, and the inductive voltage drop effects of the…
Requirements for direct acting current and voltage protective functions of direct-acting overcurrent electromechanical trip devices, direct-acting overcurrent electronic trip systems, reverse-current trip systems for dc circuit breakers, and undervoltage trip…
Diagnostic tests and measurements that are performed in the field on fluid-filled power transformers and regulators are described. Whenever possible, shunt reactors are treated in a similar manner to transformers.…
