TAURUS Z-CHECK
Transmission Line Parameter Measurement Made Simple
TAURUS Z-CHECK is a state-of-the-art instrument designed to measure transmission line parameters with precision. Its simple operational design ensures that key parameters required for commissioning transmission lines are determined in just a few steps. This significantly contributes to verifying the performance and stability of the protection system.
TAURUS Z-CHECK ensures reliable and accurate measurement of critical parameters, simplifying the commissioning process and enhancing the efficiency of transmission line operations.
- Impedance Measurement:
- Power frequency impedance for transmission lines.
- Positive/negative sequence impedance.
- Zero sequence impedance.
- Susceptance and Inductance Measurement:
- Phase-to-phase susceptance.
- Phase-to-earth impedance.
- Line-to-line mutual inductance (including zero sequence).
- Power Source: Operates on single-phase mains supply.
- Injection Voltage: Approximately 80 volts of system frequency is injected into the transmission line.
- Measurement Parameters: Voltage, current, and phase angle are recorded under specified test conditions.
- Frequency Alignment: Power system frequency is used for measurements to align with the operating frequency of protective systems.
- During line commissioning and testing, both circuits (double circuit lines) are de-energized to minimize induction and interference, which are generally negligible.
- Measured parameters include line impedance, phase-to-phase susceptance, and line-to-line mutual inductance, aiding in precise calculations for system setup.
