FAQ

 

Q:  What is a partial discharge tester?

A:   A partial discharge tester is an electrical diagnostic tool used in high-voltage engineering to detect and measure partial discharges (PD) in insulation systems. It applies high voltage to the equipment and monitors for localized breakdowns in insulation, which, if left unaddressed, could lead to equipment failure.

 

Q: What are the methods of partial discharge testing?     

A: Partial discharge testing assesses high-voltage equipment insulation. Methods include Capacitive Coupling, Ultrasonic Detection, RF, High-Frequency Current Transformer, TEV, Acoustic Emission, Calorimetric, and Ionometer. These detect signals like electric field changes, ultrasonic waves, RF, high-frequency currents, transient voltages, acoustic emissions, heat, and ion concentration, identifying and analyzing partial discharges for insulation assessment. The method choice depends on equipment and insulation characteristics, and combining methods offers a comprehensive evaluation.

 

Q: What is a PD detector?  

A: A PD (Partial Discharge) detector is a tool designed to identify and measure partial discharges in high-voltage electrical equipment, ensuring the reliability and safety of the system.

 

Q: What is the IEC standard for partial discharge tests? 

A: The IEC 60270 standard, formerly known as High-Voltage Test Techniques, specifically addresses partial discharge measurements in electrical apparatus, systems, and components. It is relevant when conducting tests with both DC voltage and AC voltage up to 400 Hz.
