Sky Tower in Auckland is New Zealand’s tallest building (328 m), this building is protected with LPI’s Guardian air terminal.

The Brief
Name of construction: Direct strike & Power line protection system for data center system of YANLAND Building in Ho Chi Minh city
Name of investor: YANLAND Co., Ltd at District 7, Ho Chi Minh City
Products have supplied for this project: Stormaster-ESE & HVSCPLUS, accessories for direct strike protection system and SF31000-480-110+50-AIMCB for power line protection system.
The year of project start & completion: 2018 / 2020

The Outcome

In addition to the standard requirement to use a dedicated HVSC Plus 8-layer noise escape cable and LPI/Australia ESE lightning rod to protect lightning protection directly for the Data center system according to ANSI / TIA-942, the quality of ac power input for the system is equally important, the system must use a surge protection device with 2 functions that both Cut and Filter the lightning pulse of LPI / Australia up to the load current 1000A, the device will protect 2 layers of lightning cutting and 1 layer of lightning filter, this lightning filter is connected to the load.

LPI/Australia's lightning filter will protect the lightning spread on the input power supply and ensure the power waveform quality for the load after the lightning pulse cutting and filtering function is completed.

At the Data Center of The Yanland Office Building, Hoang Kim Co., Ltd consulted, designed and provided comprehensive lightning protection system from Direct surge protection to spread and AC power input of data center system which has been protected by 3 phase 1000A dedicated 3 phase surge protector Model: SF31000-480-110+50-AIMCB of LPI/Australia provided by our company.

Our extensive experience with lightning problems was utilised by Australia’s Bureau of Meteorology for improving lightning mitigation at radar sites that had experienced recurring equipment damage from thunderstorms. Our consultants conducted detailed investigations at both locations, performing soil resistivity tests, earth grid continuity and resistance tests, surge and transient protection inspections, and direct-strike assessments. The Bureau was provided with comprehensive recommendations and proposed actions to mitigate the ongoing issues.

PhysElec Solutions was engaged to provide earthing and lightning protection for an advanced bird radar detection system installed at Musselroe Wind Farm in Tasmania’s far north-east. Soil resistivity and earthing design was carried out, along with a freestanding lightning protection design employing a corona minimising air terminal and insulated downconductor system. Following the installation of earthing and lightning protection, current injection testing was carried out to verify system performance.
