Lightning Impedance Tester: MODEL 4051

The 4051 lightning impulse impedance tester is used to inject a simulated lightning impulse signal at up to 30 Amps between two electrodes such as a Pylon footing and a remote test electrode. A measurement of the ground impedance between between the two is determined automatically and if the operator so chooses they may also perform a further test to determine how the same impulse can affect the potential of a nearby metallic object within the impulse path. Two tests are available: - Direct Impedance test - Electrode Impedance test These tests may be performed with one or both of the impulse wave shapes below: 8 / 20uS 10 / 350uS More impulse shapes are available upon request, (contact RPI), however the two outlined above have been found to give the most practical and consistently reliable results.
