The Class C62 (C62形) is a type of 4-6-4 steam locomotive designed by Hideo Shima and built by the Japanese National Railways (JNR). The "C" classification indicates three sets of driving wheels. The C62 was rebuilt with the boilers of older Class D52 2-8-2 locomotives.

Sep 24, 2020 · IEEE Std C62.11 ™-2020 (Revision of IEEE Std C62.11-2012) IEEE Standard for Metal-Oxide Surge Arresters for AC Power Circuits (>1 kV) Developed by the Surge Protective Devices Committee of the IEEE Power and Energy Society Approved 6 May 2020 IEEE SA Standards Board .

Some of the key changes include updating the AC voltage rating term, adding an energy handling rating for distribution arresters, lowering the standard altitude, and harmonizing several tests with IEC 60099-4. What are the major changes made in the 2020 edition of the IEEE arrester test standard C62.11?

In this paper effective performance of MOSA with different TFR and different location of MOSA from equipment to be protected is analyzed. Analysis of lightning surge on different magnitude for 132 kV and 66 kV system has been evaluated and presented.

IEEE C62-11 recommended protective margin for impulse coordination is 20% (for transmission and distribution applications). Surge voltages enter the underground system from the overhead feeder at the riser pole. The magnitude of surge voltage entering the cable is limited by the arrester on the riser pole.

Abstract: Surge arrester installation methods at distribution cable terminal poles to minimize the total impressed transient voltage on medium-voltage distribution cables are suggested in this guide. Grounding electrode techniques, pole ground values, and system ground grid values are not addressed or considered in this document.
