Development Of A Non-Fragmenting Distribution Surge Arrester

IEEE Transactions on Power Apparatus and Systems, 1984
Failure of a distribution surge arrester can result in fracturing of the porcelain housing. Although the probability of an arrester failure is extremely low, the cumulative number of failures could be substantial because of the large number of arresters installed.

Surge arrester modeling

2001 IEEE Power Engineering Society Winter Meeting. Conference Proceedings (Cat. No.01CH37194), 2002
The performance of surge arresters during electromagnetic transients on power systems can be simulated with EMTP-type computer programs. This paper discusses the steps to be performed for deriving the parameters needed to represent gapless metal oxide surge arresters in transient simulations.

Operation of Surge Arresters on Low Surge Impedance Circuits

IEEE Transactions on Power Apparatus and Systems, 1974
The normal operation of a surge arrester by a lightning stroke or switching surge requires the arrester to conduct currents, first limited by the system surge impedance and arrester resistance, and then, limited by short circuit impedance and arrester resistance.

Evaluation and diagnosis technique for surge arresters

2010 International Conference on High Voltage Engineering and Application, 2010
This paper presents the development of a diagnosis technique, used on-site, applied in the evaluation of station type surge arresters, of SiC and ZnO installed in FURNAS' electrical system. Thermovision, leakage current and radio interference techniques were used in on-site measurements.

Diagnostic of silicon carbide surge arresters

2010 International Conference on High Voltage Engineering and Application, 2010
The gapped silicon carbide (SiC) surge arresters are being removed from the operating system of the utilities, however, a large number are still installed in the power system. Therefore, it is very important to give priority to SiC surge arresters that are more degraded in order to replace them by the zinc oxide (ZnO) ones.

Comparison of Surge Arrester Models

IEEE Transactions on Power Delivery, 2014
This paper deals with the two most used arresters models applied in digital simulations with the Alternative Transients Program, the conventional, and IEEE models. It presents a model analysis and parameter adjustment procedures to the conventional model.

Modeling of Current-Limiting Surge Arresters

IEEE Transactions on Power Apparatus and Systems, 1981
This report presents a simplified silicon-carbide surge arrester model suitable for analog and digital studies of switching transients on overhead HV and EHV lines. The report also includes a guide for the application of the model in the selection of arrester ratings and insulation levels. The model is based on current-limiting arrester designs, but it

Mov surge arrester's failure analysis

2015 IEEE/IAS 51st Industrial & Commercial Power Systems Technical Conference (I&CPS), 2015
This paper provides catastrophic failure analysis of all three (3) station-class metal-oxide varistor (MOV) surge arresters located inside the metal-clad switchgear. All three surge arresters failed causing major damage to the switchgear without any evidence of switching surge activity. Analysis concludes that the B-phase surge arrester internal damage

Surge arresters models for fast transients

2012 International Conference on Lightning Protection (ICLP), 2012
In this paper is presented the performance of metal-oxide surge arresters, during fast transients. The simulations were carried out with the EMTP-ATP program. The equivalent circuits were those proposed by the IEEE and Pinceti-Giannettoni. The residual voltages of various rated voltages lightning arresters and for lightning currents with different peak

Development of a new surge arrester technology

Power Engineering Journal, 1991
A new arrester design concept using a resistance-graded series gap and a reduced MOV disc stack offers substantial improvements in temporary overvoltage performance, protective levels and durability over conventional gapless MOV ...
