How are capacitance and inductance tests performed?
Apply test voltages at different frequencies, acquire voltage, current, and phase data, calculate capacitance or inductance based on impedance relationships, and output the associated electrical parameters.
How are handover tests for capacitor banks conducted?
For shunt capacitor banks that have been newly commissioned or undergone major overhauls, individual capacitor units can be tested and three-phase balance verified to detect capacitance drift or failed units.
Inductance measurements of series reactors, arc-suppression coils, and instrument transformer windings can be performed to support equipment condition assessment.
What are the main interfaces?
Voltage output, voltage input, and current input terminals; thermal printer; 7-inch LCD; 220V socket; USB port; serial port (optional); grounding terminal.
Connect thick wires to the large voltage output terminals and thin wires to the small voltage input terminals.
What are the wiring methods for single-phase and three-phase systems?
Single-phase: Connect the yellow clip to the positive terminal and the black clip to the negative terminal; simply clamp the current probe onto the positive terminal. If using the built-in CT, no external current probe is required. Ensure safety regarding discharging and grounding before and after measurement.
Three-phase: Depending on the connection type (Y, Yn, D, or III), use the red and black clips to connect sequentially according to the phase (e.g., for Phase A, connect the red clip to A and the black clip to B, then rotate for Phases B and C). In three-phase mode, the built-in CT is used, so no external current probe is required.
What is the storage capacity for the Capacitance and Inductance Test?
Features built-in non-volatile storage for 500 data sets (with USB export capability for any selected set) and a real-time clock for timestamping.
Optional features include Bluetooth smartphone control, serial communication, and external printer connectivity, facilitating data management and on-site report printing.
How do I consolidate the results after measuring the three phases?
Once the tests for all three phases are complete, the interface automatically displays the summary results; you can then select "Test" to re-run the test or restart from Phase A.
FAQ
Q1: What happens if the wrong connection configuration (Y/Yn/D/III) is selected?
A: The selected configuration must match the actual internal wiring of the capacitor bank; an incorrect selection will lead to unreliable results. Please verify the capacitor bank's wiring method before measurement.
Q2: What support services are included?
A: Factory calibration, operational training, technical support, and spare parts/repair services are provided to ensure long-term, stable operation.
Q3: What are the communication and printing options?
A: Options include Bluetooth control via smartphone, serial communication (optional), and external printer support, facilitating data management and on-site report printing.
