Analysis Of Transient Recovery Voltage (TRV) Rating Concepts
IEEE Transactions on Power Apparatus and Systems, 1984The basis for TRV standards both ANSI and IEC were developed about twenty years ago. While the requirements are similar, there are significant differences. These differences are examined with some of the assumptions behind them. With the recent emphasis towards harmonization of ANSI and IEC standards, it appears that the data and assumptions need to be

Improved Autotransformer Model for Transient Recovery Voltage (TRV) Studies
IEEE Transactions on Power Delivery, 2012A three-phase ungrounded fault supplied by a single autotransformer produces a transient recovery voltage (TRV) that is often the worst case for a circuit breaker (CB). This is the so-called “transformer limited fault.” The transformer model is extremely important for computing this TRV because it is the key element in the circuit.

Tobacco Rattle Virus (TRV)-Based Virus-Induced Gene Silencing
2012One of the most effective forms of plant defense against viruses is posttranscriptional gene silencing (PTGS). This process implies that a virus can trigger the host plant's RNA-silencing machinery and ultimately become the target of RNA silencing. PTGS is, therefore, an attractive endogenous process that can be exploited to study gene function. One of

Investigation of Tangential Line and Prospective Values for TRV Measurements
IEEJ Transactions on Power and Energy, 2013SUMMARYThe prospective transient recovery voltage (TRV) at current interruption for circuit breakers should be measured by using an ideal circuit breaker. Prospective values of the TRV are obtained by drawing the tangential line to the TRV waveform.

On series compensation impact on line protection and TRV
41st North American Power Symposium, 2009Series capacitors are a well established concept within electric power transmission, finding ever increasing use in EHV and UHV transmission grids to provide benefits such as improved voltage and transient stability of long lines as well as improved power division between parallel lines.

Sensitivity analysis of TRV in series compensated transmission lines
2017 2nd IEEE International Conference on Recent Trends in Electronics, Information & Communication Technology (RTEICT), 2017The characteristic of Transient Recovery Voltage includes Peak Amplitude & Rate of Rise of Restriking Voltage which significantly affects operation of the circuit breaker to interrupt fault current successfully. The paper intends to analyze the Transient Recovery Voltage characteristics across circuit breaker of line with the topology of series ...

Revision of TRV requirements for the application of generator circuit-breakers
Electric Power Systems Research, 2016Abstract The requirements imposed on generator circuit-breakers greatly differ from the requirements imposed on other transmission and distribution circuit-breakers. Due to the location of installation between the generator and the associated step-up transformer, a generator circuit-breaker must meet high technical requirements with respect to rated ...

TRV (Transient Recovery Voltage) in High Voltage Current Interruption
2018 IEEE IAS Pulp, Paper and Forest Industries Conference (PPFIC), 2018This paper provides concepts of transient recovery voltage (TRV) in ac high-voltage interruption. The ANSI/IEEE and IEC standards differ in the TRV profiles. This paper describes the TRV profiles according to these standards and compares these with practical calculations. Working examples of calculations in practical systems are included.
