Impedance tester UHV-725

capacitancepowerfrequency

The UHV-725 Automatic Capacitance and Inductance Tester measures per-phase capacitance, total capacitance and inductance of compensation capacitors. It is designed to simplify wiring and operation to reduce maintenance workload and improve on-site testing efficiency and safety.

Key features

• Measure single capacitance of a group of parallel capacitors without disconnecting wiring; displays measured capacitance along with voltage, current, loss, frequency and impedance.
• Displays measured inductance together with voltage, current, loss, capacitance, frequency and impedance.
• Displays measured current and related parameters such as frequency during testing.
• Supports measurement of capacitor groups and both △ (delta) and Y (wye) configurations.
• 320×240 large LCD with menu prompts for easy operation.
• Built-in large-capacity non-volatile memory: each test option can store up to 256 data sets.
• Built-in USB interface for exporting stored data to facilitate report generation.
• Built-in high-precision real-time clock for date/time stamping of measurements.
• Includes a high-speed micro thermal printer for printing measurements and historical data.
• Overcurrent protection on the test power supply: output short circuit will not damage the instrument.
