Seismic resistance level classification of communication base station inverters

What are seismic design recommendations for substations?

Abstract: Seismic design recommendations for substations, including qualification of different equipment types are discussed. Design recommendations consist of seismic criteria, qualification methods and levels, structural capacities, performance requirements for equipment operation, installation methods, and documentation.

Does ABB critical power have seismic certification?

Energy commander two-bay cabinet Paralleling Switchgear (PSG) is included. Seismic certification is frequently required in mission critical facilities applications and the ABB Critical Power products are rated to perform successfully during and after seismic activity. The IBC code supersedes previous building codes (NBC, SBC, UBC).

Are ABB products seismic rated?

Seismic Rating Information and ABB product compliance Electrical Distribution Products ABB completed an extensive 3D shake-table test program to certify the seismic capabilities in accordance with the International Building Code (IBC-2012, 2015, 2018) on a full range of products.

What is seismic design category C?

Stratified soils with Good and poor Soils. Seismic Design Category C – Corresponds to buildings of Occupancy Groups IV (Hospitals, Police Stations Emergency control centers etc.) I where expected ground shaking will be MODERATE AND buildings of occupancy categories I, II, and III where MORE SEVERE ground shaking will occur.

What is the IBC code for ABB equipment?

The IBC code supersedes previous building codes (NBC, SBC, UBC). Equipment importance factor (from 1.0 to 1.5). Unless otherwise noted, all ABB equipment with seismic certification is qualified to an Ip level of 1.5, indicating the equipment will be fully functional during and after a seismic event.

How do I comply with IBC seismic requirements?

Compliance with the seismic provisions of IBC requires either shake-table testing in three orthogonal directions or mathematical modeling incorporating techniques, such as finite element analysis, to establish whether the product can withstand the required amount of seismic activity.
