HV Hipot Brand Handheld PD Detector for Switchgear
TEV and AE method is acknowledged and suitable technology to be used in online partial discharge detection.
GDPD-313M uses ultrasonic detection technology(AE) and TEV mode, which can effectively ensure signal sensitivity in the interference on-site environment . It is suitable to detect PD flaw and locate PD signal for switch cabinet etc.
Features
Built-in ultrasonic sensor; electrical fault generates ultrasonic wave at the fault point, and ultrasonic mode transmits the ultrasonic signal through the earphone to scan the area to detect the discharge. Various characteristics of vibration, pop, and hum can be associated with different faults.
Built-in high-precision TEV sensor, coupled with electromagnetic signals generated by partial discharge, to identify potential internal discharge failure risks.
In Ultra Mode, the main interface displays the partial discharge amplitude (dBuv), and uses the yellow, green and red colors to increase the severity of the partial discharge. At the same time, the headphone listening volume (Vol) can be adjusted.
In the transient radio mode (TEV Mode), the main interface displays the partial discharge amplitude; the number of pulses, the total number of pulses and the discharge intensity level in each power frequency cycle.
Powered by rechargeable lithium battery, continuous working for more than 6 hours.
True color LCD display, real-time battery power prompt; physical film button is easy to use and equipped with external high-fidelity noise reducing headphones.
Adopting a color LCD screen, using a graphic and digital display mode, it is possible to intuitively know whether the partial discharge amount exceeds the standard.
Simultaneously integrate the two methods of transient ground wave and ultrasonic to facilitate on-site use. It can detect various discharges in electrical equipment such as medium and high voltage switchgear (3~66kV) and is suitable for many different types of power equipment.
