Product Introduction
To reduce reactive power loss in power systems, shunt capacitor banks are commonly used to improve the power factor. In practical applications, capacitor compensation devices tend to have a relatively high accident rate due to the inherent characteristics of capacitor operating conditions. Therefore, regular inspection of capacitor banks and early detection of potential defects are essential to preventing fault escalation.
In field applications, capacitors within a bank are connected in parallel. When using a conventional capacitance meter, workers must disconnect the leads to perform measurements—a process that is labor-intensive and prone to wiring errors. To address this challenge, our company has developed a new Capacitance and Inductance Tester. This instrument allows measurement of individual capacitors within a parallel-connected bank without disconnecting any leads, and is also capable of measuring inductance and current. With convenient wiring and simple operation, it significantly reduces the workload of maintenance personnel, greatly improves on-site testing efficiency, and ensures the reliable operation of the power grid.
Product Characteristics
1. Capacitance Measurement Without Disconnection: The instrument can measure individual capacitors within a group of parallel-connected capacitors without disconnecting any leads, greatly simplifying testing. It simultaneously displays measured voltage, current, loss, capacitance, frequency, impedance, and other relevant data.
2. Inductance Measurement: In addition to displaying the measured inductance value, the instrument also shows voltage, current, loss, capacitance, frequency, impedance, and other parameters.
3. Support for Various Connections: In addition to testing individual capacitors within a group, the instrument can also measure capacitors connected in Δ-type (delta) and Y-type (wye) configurations.
4. User-Friendly Display and Interface: Features a 320×240 large-screen LCD with Chinese menu prompts, making operation simple and intuitive.
5. Built-in Large-Capacity Memory: Each test option can store up to 256 sets of data in the built-in non-volatile memory.
