Has your PRPD (Phase Resolved Partial Discharge) ever been affected by two or more PD activities and overlapping noise at the same time? Even very skilled operators will find hard to make a diagnosis, in situations as the one mentioned above, through a mere visual evaluation of the pattern graph. Techimp new technology bases itself on the principle that efficient separation and identification of PD data can be achieved collecting PD pulses themselves and not only, as digital instrumentation commonly available does, PD pulse peak and phase.

A Hi-Tech corporation acting as a stockist and supplier of Partial Discharge (PD) Diagnostic Test Kits plays a crucial role in offering advanced diagnostic tools used to detect and analyze Partial Discharge activities in electrical equipment, such as transformers, cables, switchgear, and motors. These activities are indicators of potential faults or aging within the electrical insulation system, and early detection is essential for preventing catastrophic failures.

Role of Hi-Tech Corporation as Stockist and Supplier:

1. Stockist: As a stockist, the corporation maintains an inventory of PD diagnostic test kits, ensuring they are readily available for customers such as electrical utilities, maintenance companies, and industries that require frequent monitoring of their electrical assets.

2. Supplier: The company supplies these diagnostic kits to various clients, including industries that require regular PD testing for preventative maintenance. The supplier also offers technical support, product training, and maintenance services for the diagnostic equipment.

Key Technical Specifications of a Partial Discharge (PD) Diagnostic Test Kit:

A PD diagnostic test kit typically includes both hardware and software components designed to measure and analyze the occurrence of partial discharge. The specifications may vary between manufacturers, but common features include:

1. Measurement Range:

   • PD Detection Range: Typically from 1 pC (picoCoulomb) to several micro-Coulombs (μC), depending on the sensitivity of the instrument.
   • Voltage Range: Some kits can work with both low and high voltage equipment (e.g., up to 400kV or higher).

2. Sensitivity:

   • Sensitivity Level: The test kit should be capable of detecting very low levels of partial discharge, which is critical for early fault detection.
   • Frequency Range: Detection systems often operate in a frequency range from a few Hz to several MHz, matching the typical PD signals from electrical equipment.

3. Signal Detection and Display:

   • Time-domain Analysis: For detecting the occurrence and timing of PD events.
   • Frequency-domain Analysis: PD signals often manifest as high-frequency noise that can be analyzed in the frequency spectrum to identify fault patterns.
   • Waveform Capture and Visualization: Display the waveforms of detected PD, which can help diagnose the type and location of the problem.
   • Pulse Shape Analysis: Analyzes the shape and duration of individual PD pulses to help identify insulation defects.

4. Measurement Method:

   • Acoustic Sensors: Used to detect ultrasonic PD signals generated in electrical equipment.
   • Electrical Sensors: Current transformers or capacitive dividers to measure the electrical signals.
   • UHF (Ultra High Frequency) Sensors: Detect PD signals emitted in the UHF spectrum.
   • Optical Sensors: For specific applications where optical PD signals are present.

5. Data Logging and Analysis:

   • Real-time Data Logging: Continuous recording of PD events for trend analysis over time.
   • Software Interface: Typically comes with proprietary software to analyze, store, and generate reports of the diagnostic test data.
   • Cloud or Remote Monitoring Capability: Some modern PD diagnostic systems allow remote data monitoring and analysis via cloud-based platforms.

6. Portability:

   • Compact and Portable Design: 

The VBT-75 S2 is Vanguard's second generation microprocessor-based, portable, 75kVdc vacuum bottle tester.
This lightweight, portable tester is designed for testing circuitbreakervacuum bottles in the field and at the shop.
Test voltages can be selected from 10 kV dc to 75 kV dc in 5 kV steps. The high-voltagetest time can be set from 5 seconds to 2 minutes. The test voltage is raised to the selectedvoltage and held for the test time duration. After the test time duration has elapsedand the leakage current did not pass the preset value of 100 μA, 200 μA, or 300 μA, thetest voltage is returned to zero and a "Pass" message is displayed. If a flash-over conditionoccurs, such as bottle failure, the test voltage is immediately turned off, a “Failure”message is displayed on the LCD screen, and the “TEST FAIL” LED light on the unit is alsoilluminated.outstanding features
