Capacitor Inductor Meter

Dual Canopy Mechanic Electrical Engineering Co., Ltd. is one of the leading manufacturers and suppliers of Capacitor Inductor Meter in China. Please feel free to wholesale discount products for sale here and get quotation from our factory. Customized orders are welcome.

The Capacitor Inductor Meter handles precise characterization of capacitors and inductors in a single unit. It captures the parameters that matter most-capacitance, inductance, equivalent series resistance (ESR), loss tangent (tan δ), quality factor (Q), impedance, and phase angle-with the accuracy needed for professional diagnostics.

Power system technicians rely on it to monitor the health of parallel compensation banks, filter capacitors, series resonant units, transformer magnetizing inductors, and line reactors. The instrument picks up on gradual degradation such as capacitance drift, escalating dielectric losses, or rising ESR before these issues lead to failure. These measurements translate directly into actionable intelligence for maintenance planning and asset condition evaluation.

.

• The instrument can not be dismantled to measure a single parallel capacitor, testing is convenient, display the measured capacitance value at the same time can also measure the voltage, current, loss, capacity, frequency, impedance, resistance, reactance and other data;
• The instrument shows the measured inductance value and can also measure the voltage, current, loss, capacity, frequency, impedance, resistance, reactance and other data;
• The instrument displays the measured current value and at the same time can also display the frequency of the current and other data;
• In addition to measuring the group capacitor, the instrument can also measure △ type, Y type connection capacitor;
• 320×240 large-screen liquid crystal display and Chinese/English menu makes it easy to operate;
• Built-in large-capacity non-volatile memory: Each test option can store 256 sets of data;
• Built-in USB controller interface can export instrument memory data,which makes it easy for report generation;
• Built-in high-precision real-time clock function for date and time calibration;
• The instrument comes with a high-speed micro thermal printer to print measurement and historical data;
• Function of test power supply over-current protection can ensure the instrument will not be damaged when the power supply outputs short circuit;
• The instrument has built-in 4000mAh rechargeable lithium battery, standby time of 6~8 hours, convenient for on-site use.

Regular inspection of test leads and clamps: Check for insulation aging, connector oxidation, and clamp elasticity. Clean contact surfaces regularly and replace any deteriorated leads promptly.

Regular verification of open/short circuit compensation: After replacing test leads or after prolonged use, recalibrate open/short circuit compensation to ensure measurement accuracy.

Battery maintenance (if applicable): Avoid prolonged storage with a low charge; if not used for an extended period, it is recommended to recharge the battery monthly to maintain battery health.

Cleaning and moisture protection: Store the instrument in a dry environment; use dust covers to protect interfaces to prevent moisture from affecting the measurement circuitry.

Calibration recommendations: For acceptance testing or third-party testing, it is recommended to calibrate annually or according to the company's internal control cycle, and retain the calibration certificate number.

Software data backup: Regularly export and back up important test data to prevent overwriting due to full storage space.

Remote technical support: Guidance on lead wire compensation operation, measurement frequency selection, ESR/tan δ result interpretation, and data export issues.

Spare parts supply: Long-term supply of test leads, fixtures, power adapters, etc.

Calibration and repair: Support for factory calibration and repair to meet metrology and audit traceability requirements.

Retraining service: Retraining provided for measurement methods, lead wire compensation, and result interpretation when team members change.

Q1: How to choose the test frequency?

A: Generally, choose a test frequency close to the component's operating frequency; for power capacitors, 50Hz or 100Hz is usually chosen; for high-frequency filter capacitors, a higher frequency can be selected (as supported by specifications and model).

Q2: Why are the measurement results different at different frequencies?

A: Capacitance and loss characteristics are usually frequency-dependent. The C/L/ESR values ​​of non-ideal components will change with frequency; for the same object, a fixed frequency should be used for trend comparison.

Q3: Is open-circuit/short-circuit compensation mandatory?

A: It is recommended for high-precision measurements (such as low ESR, small capacitors); it can be omitted for ordinary measurements, but the accuracy of the results will be affected by the leads.
