What does an Automatic Capacitance Inductance Tester do?
The Automatic Capacitance & Inductance Tester is a multifunctional impedance analyzer engineered for in-situ evaluation of reactive components. It eliminates the need for busbar removal by performing non-intrusive measurements directly on energized or de-energized banks, dramatically reducing both outage duration and the likelihood of inflicting collateral damage during inspection.
Equipped with advanced auto-identification algorithms, the instrument distinguishes between capacitive, inductive, and resistive test objects without manual range selection. Upon connection, it automatically configures the optimal measurement parameters and displays the component type, nominal value, and equivalent series resistance (ESR) or quality factor (Q) as applicable.
Beyond capacitance and inductance measurement, the unit incorporates a standalone current-detection channel. This allows operators to perform load-current surveys, inrush-current capture, or harmonic current profiling independently, effectively consolidating multiple field instruments into a single portable platform.

On what principle does the Automatic Capacitance Inductance Tester operate?
A test voltage at a specific frequency is applied to the device under test; the voltage, current, and phase within the sampling circuit are measured to calculate the capacitance or inductance value based on impedance relationships, while simultaneously determining associated parameters such as voltage, current, frequency, impedance, and phase angle.
A differential frequency power output is employed to shift the test signal away from the frequency band of power-frequency interference, thereby significantly enhancing anti-interference capability and ensuring measurement accuracy even in strong magnetic field environments.
How do you test single-phase and three-phase systems?
Tap the "Three-phase Measurement" icon, select the test type (capacitance/inductance) and wiring configuration (Yn/Y/D/III), and enter the rated voltage. Upon startup, the device automatically measures each phase sequentially and compiles the results after all three phases are completed; the three-phase mode utilizes the built-in CT, requiring only voltage lead connections.
Tap "Single-phase Measurement" to select the test type (capacitance, inductance, or resistance). Current can be measured via the built-in CT or an external current clamp. After entering the rated voltage and starting the test, results can be saved and printed, and the test can be repeated.
How should the capacitor be wired when testing single-phase or three-phase systems?
Single-phase: Connect the yellow clip to the positive terminal and the black clip to the negative terminal; measurement is performed by clamping the current clamp onto the positive terminal. If using the built-in CT, no external current clamp is required.
Three-phase: Depending on the configuration (Y, Yn, D, or III), use the red and black clips to connect to the corresponding busbar phases in sequence (e.g., for Phase A, connect the red clip to A and the black clip to B, rotating through the phases); in three-phase mode, use the built-in CT without an external current clamp.
Can accurate measurements be made in a strong magnetic field environment?
Yes. Differential-frequency power supplies separate the test frequency from on-site power-frequency interference, significantly enhancing anti-interference capabilities and ensuring accuracy is maintained even in strong magnetic fields near high-voltage equipment.
In environments with complex electromagnetic conditions-such as substations and power plants-where traditional instruments are susceptible to induced voltage, differential-frequency technology ensures stable and reliable readings.
