The TVM1100 is designed for use with the LCI2000C injection unit to detect the voltages generated by the injected current. Due to its excellent noise rejection very low levels of test voltage may be identified, even where the background noise levels is high. Such noise may result from residual voltage on the earth grid, electric field coupling or induction into test cables.
The TVM1100 has a high input impedance to ensure accurate reading of prospective touch, step and transferred voltages. It also has a switchable low input impedance (1 kΩ) to simulate a person’s body impedance. The TVM1100 includes a second input for a flexible or clamp CT to enable current splits and associated phase angles to be measured, as well as GPS tracking and data logging. The GPS facility is ideal for the earth potential rise traverse while the data logging enables any readings to be recorded.
