Tower footing resistance on the laboratory pole was varied from 10 to 200 ohm and tested using compact SPS, SSS and PSS. An error of +/- 6.55% and +/- 8.86% was observed on ungrounded and grounded field poles respectively when the compact Single Point System (SPS) was employed.All programs were uploaded on Dell Latitude model C600 laptop computer. A Tektronics TDS 3014 oscilloscope was. Figure 4-6 A 94 Hz band-pass filter schematic [1| Figure 4-9 GMR sensor chip and sensor box. 40 Laboratory Equipments.
