Soken DAC-6021 - Partial Discharge Measuring System

DAC-6021 is the ideal system for partial discharge measurements of electrical and electronic devices, such as EV motors, IGBTs as well as high-frequency transformer components and insulating materials. The system is composed of a partial discharge measurement device, a high-voltage test power source, a detector, a coupling capacitor, and a safety test chamber, and is capable of automatic testing with less influence of noises.

Application

• EV motor
• IGBT
• High-Frequency Transformer
• Ceramic capacitor
• Electrical insulation materials

Test Items 

Integrating a partial discharge measuring instrument, detector, coupling capacitor, and a test chamber into a system rack, the PD test system realizes simple and safe operation. The operator can perform a test by entering or recalling specific test parameters. The specified test can be repeated, and stored in a database and printed. 

System Configuration Example

• Test Item: Qmax, PDIV/PDEV testing
• Test Voltage: AC0 - 5000V
• Test Frequency: 46Hz - 1kHz
• Input Power ：AC100V/200V 50/60Hz
• Dimension and weight ：W570×H1500×D630(mm) about 100kg

1. Safety Test Chamber

   Built-in Detector, Coupling capacitor, Blocking coil type. By measuring the sample in the chamber, the voltage application part is isolated to realize safe operation. The whole chamber is connected to ground potential, and ambient noise is shielded from the measuring circuit.

2. Partial Discharge Measuring Instrument Model DAC-PD-3

   Frequency bandwidth:
   Narrow：10kHz - 200kHz
   Wide ：10kHz - 4MHz
   

3. Withstand voltage test set

   Model DAC-WT-50
   AC 0 – 5000V (<10pC @ 5000V)
   Variable Frequency 46Hz - 1kHz
   

4. Output Terminal for Monitoring Waveform

   With a slide-table for PC type. By connecting the oscilloscope, Voltage waveform and Partial discharge waveform can be observed.
   

5. Main Power Breaker

6. Warning Indication Light

7. Emergency Stop Switch

Please consult us for a higher test voltage system. (Max 30kV) We also propose a system that can switch test points, which is desirable for a 3-phase product such as a 3-phase stator.

Software

• PD Test Voltage – Time Characteristics (T-Qmax)
  Apply an optional voltage to the sample for an optional time to obtain the discharge charge amount. Max 4 types (A, B, C, and D) voltage-time measurement patterns can be registered and judgment can be made for each pattern.
  

• PD Test voltage – Discharge Charge Amount Characteristics (V-Qmax)
  Perform PDIV/PDEV test. The voltage applied to the sample is increased at a constant speed to determine the partial discharge inception voltage, and decreased to determine partial discharge extinction voltage.
  

• PD Occurrence Frequency – Discharge Charge Amount Characteristics (N-Qmax)
  Apply a certain voltage to the sample and count the number of partial discharge occurrences at each charge amount. Test voltage of max 15 levels can be input and data at each test voltage can be obtained.
  

• Qmax, PDIV, PDEV test with software
• Test Voltage range: 0 - 5kV (max 30kV upon request)
• Test Frequency: 46Hz - 1kHz
• Design for safe operation
• Shielded from the external noise
• Interlock function
• Warning light
• Emergency Stop function
