Taer Lamasery is one of very high value because of its Buddhist historical and cultural importance. The electrical storm of August 30, 2011 caused some damage to the fire security equipment and high voltage distribution system at ShiLuntan and DaJiewa Hall. Potential lightning strikes seriously threaten the safety of monks and tourists. An anti-ligntning protective system is very necessary and is urgently needed for the historic buildings of Taer Lamasery. Based on the characteristics of the buildings’ geographical environment, climate features and risk of lightning strikes, new protection measures, both internal and external, are proposed. The external protective system consists of a lightning rod installed in the path of lightning so as to meet flash in advance, and a protection zone installed on the top of the building to meet the secondary flash. In this way, the external protective system effectively prevents or reduces the direct lightning strikes. The internal lightning protection system utilizes the techniques of shielding, appropriate wiring, equipotential connections, and power and surge protectors at the entrance and exit routes of the building. The internal protective system prevents and reduces the danger of inductive electric wave invasion. Analysis shows that proposed lightning protective system at the Taer Lamasery is feasible, and has great reference value for protection of other ancient buildings with similar environment.
