Original product description
The partial discharge detector integrates ultrasonic, TEV (Transient Earth Voltage), and UHF (Ultra High Frequency) technologies to detect partial discharges in middle-high voltage equipment. PDS3 can monitoring of transformers, high-voltage switchgear, and cable joints.
PDS3 is highly portable, offers fast measurement speeds, and boasts strong anti-interference capabilities, making it suitable for various field applications.
Rugged, compact design;Non-intrusive detection method;Strong magnets to attach sensor;Rapid detection of partial discharge conditions;Easy to Install, integrated transient (Over-voltage) protection;Suitable for extreme environment, outdoor substation;Measures PD in high-frequency UHF range;Ensures sensitive PD measurements in noisy environments;Designed specifically for PD detection at HV cable terminations;RS485, Modbus-RTU, SCADA systems.
Feature 3.1.- Ultrasonic measurement If you choose the external ultrasonic sensor to measure the partial discharge of the switchgear you hardly need to do other operations or settings after starting up, Because the external ultrasonic sensor is selected by default after the product is turned on, the upper left of the screen will display which sensor is currently connected.
In the ultrasonic measurement mode, the measurement data is d. Buy, because d. Buy is a logarithmic function value based on 1uv, therefore, the measured data in the ultrasonic mode can be positive or negative. According to the processing capacity of the ultrasonic amplifier of this product. it can reach -6d.
BuV The test ranges to 68d. Buv, the larger the negative value. the smaller the ultrasonic signal, the closer to Ouv, not negative! Usually,y the measured data in an interference-free environment is between -6d. BuV and od. BuV.
3.2.-TEV measurement In the TEV measurement mode, the reference pulse count value P/Cycle is also required, and the pulse number and amplitude comprehensively measure the health of the switchgear. When the environmental value is large, it is necessary to find out the interference source.
The interference source of TEV is different from that of ultrasonic. Ultrasonic interference is generally limited to a limited space, while TEV interference affects the entire space through radio frequency such as electric welding machines, frequency converters, walkie-talkies, Wireless broadcasting stations, etc .
Compared with ultrasonic interference, such interference signals are sometimes difficult to avoid or clear, so it is recommended to use ultrasonic measurement when the environment (interference)value is detected to be large.
3.3.-UHF measurement UHF sensor principle is to detect the ultra-high frequency electromagnetic wave signal generated by partial discharge in power equipment through ultra-high frequency sensors, to obtain relevant information on partial discharge and realize partial discharge monitoring.
Since the corona interference on site is mainly concentrated below the 300MHz frequency band.
the ultra-high frequency method can effectively avoid the corona interference on site, has high sensitivity and anti-interference ability, can realize the location of discharge source, can identify type of insulation defects, etc, is sensitive to the speed of pulse change, is more suitable for the internal discharge of dielectrics, can make up for the shortcomings of ultrasonic and transient ground voltage detection methods, and effectively improve the accuracy of diagnosis.
