Electromagnetic Interference (LFI & EPR)

The following are the main projects undertaken:

Te Awamutu Reinforcement 110-kV overhead line railway, low frequency induction assessment. Assessment was for determining & quantifying the mutual interference effects that the proposed Waipa Networks Ltd 110-kV overhead line (OHL) has on the existing Kiwirail railway assets. In this regard the assets included the railway; signalling, communications & 400 V power supply cables (New Zealand)

Transpower NAaN project; Earthing study & design report for 220-kV cable support steelwork earthing along Waipuna & Ti Rakau bridges (New Zealand).Potential 50 Hz A.C.
