Product Description
Dielectric Loss Measurement helps assess the condition of insulation in electrical equipment. By measuring dielectric loss, technicians can identify moisture, insulation aging, and some local defects before they lead to more serious problems. This test is commonly used in manufacturing, installation, commissioning, and preventive maintenance. Typical applications include transformers, reactors, capacitors, bushings, surge arresters, and other high-voltage equipment.
Wrindu's Capacitance Tan Delta Testing Kits breaks free from traditional bridge measurement methods. Variable frequency power supply technology provides flexible frequency adjustment during testing. A built-in microcontroller handles signal conversion and data calculation automatically. The system offers good interference resistance, fast testing, and accurate measurement results. Digital processing and a simple operating interface also make daily testing easier.

Testing Applications
What Can This Tan Delta Test Kit Test?
Dielectric loss testing is commonly used to check the insulation condition of high-voltage equipment. This tan delta test kit can measure capacitance and dielectric loss for different types of electrical equipment and insulation components. Typical applications include transformers, reactors, capacitors, bushings, surge arresters, CTs, PTs, and CVTs.
The instrument supports both internal and external high-voltage test modes. This gives technicians more flexibility when testing equipment with different capacitance and voltage requirements.
How Does the Tan Delta Test Kit Improve Field Testing?
Field conditions can make dielectric loss measurements more difficult. Power frequency interference, grounding conditions, and nearby electrical equipment may affect the measurement.
This instrument uses variable frequency technology to reduce 50 Hz power frequency interference. It can maintain the specified accuracy even when interference reaches 200%. The 40.0–70.0 Hz test frequency range also allows technicians to select a suitable test frequency for different site conditions.
The built-in microprocessor handles measurement and data calculation automatically. After selecting the required test mode, operators can complete the test without carrying out complex manual calculations.
What Parameters Can Be Measured?
The instrument measures several electrical parameters during dielectric loss testing. Capacitance can be measured from pF to μF ranges, depending on the selected high-voltage source and test voltage.
| Parameter | Measurement Capability |
|---|---|
| Capacitance (Cx) | 3 pF to 30 μF, depending on test mode |
| Dielectric Loss (tgδ) | No fixed range limit; resolution up to 0.001% |
| Test Current | 10 μA–5 A |
| Test Frequency | 40.0–70.0 Hz |
| Capacitance Resolution | Up to 0.001 pF |
| Parameter Identification | Capacitance, inductance, and resistance |
What Should Technicians Consider Before Testing?
Good preparation is important for reliable dielectric loss measurements. Before starting a test, technicians should check the test object, grounding condition, test connections, and surrounding electrical environment.
The selected test mode should match the equipment under test. For example, CVT testing may require the dedicated CVT function, while other insulation components can use the appropriate GST or UST test mode.
The instrument provides grounding protection and touch protection functions, but operators should still follow the required high-voltage safety procedures and site regulations during testing.
