Weshine Electric Manufacturing Co., Ltd
High-voltage Dividers (High Potential Divider) are used to measure voltages and decouple partial discharges in high-voltage test systems. Depending on the specific type, they are used to measure alternating voltage (AC), direct voltage (DC), lightning impulse voltage (LI), and switching impulse voltage (SI) systems. High-voltage dividers by HIGHVOLT comply with the relevant IEC standards. The systems are available for both indoor and outdoor use.

FMC -
Techimp HQ S.r.L
The FMC (Flexible Magnetic Coupler) is a partial discharge sensor whose working principle is based on a direct magnetic coupling with the cable conductor and shield.It picks up a magnetic signal given by PD activity. His compact and robust design makes the FMC the optimal sensor for direct installation on cables and accessories such as joints and termination.This sensor has a sensitive side which has to face to the object under test, while the other side (shielded) reject the noise from the environment.

SG9101 -
Shanghai Jiuzhi Electric Co., Ltd.
Interference Distinguishing Partial Discharge (PD) Detector is a new type apparatus developed by the institute after SG-8001 (modeled from Model-5), SG-8201 and SG-8601 PD apparatuses. Basically it keeps the merits and functions of the above three types apparatuses. SG9101 adopts special interference distinguishing logical circuit, which can discriminates the accidental interference. (The interference must be high than a set threshold and last 4 test periods at least, the “effect” will be shown). Cooperating with the time window, it can enhance the ability to discriminate and eliminate external interference.

HFCT Ø 140mm -
Techimp HQ S.r.L
Techimp Clamp High Frequency Current Transformer model 140 is an inductive sensor for partial discharge measurements. It is suitable for online /off line PD tests on : large diameter cables ; grounding rod bar ; etc. A TNC termination is available to connect the Clamp HFCT 140 to the TechImp PD analyzer : PDCheck , PDBase etc. The arrow indicates the requested input current (Iin) direction to get coherent output voltage (Vout) polarity respect to ground. When the sensor is installed with the arrow directed to ground, the detected voltage signal (Vout) has the same phase of the input current (Iin).

PDStar -
Power Monitoring and Diagnostic Technology Ltd.
PMDT is proud to present one of our latest innovations, the PDStar. It integrates On-Line Partial Discharge (OLPD) testing and Infrared testing for MV and HV equipment, which combines UHF, AE, Ultrasonic, HFCT, TEV, and Infrared testing technologies. It is applicable for online PD testing, as well as abnormal heating and defect detection on all types of substation equipment. PD amplitude, PRPD, PRPS, and infrared spectrums provide critical data for determining the operational condition of electric power equipment. It connects to the PMDTCloud via Wi-Fi/3G/4G to upload test data, download test tasks, and receive diagnostic results in real time. Another uniquely advanced feature of the PDStar is that it integrates with a 100 MSPS (Mega-Samples per Second) HFCT signal processor, which greatly improves the performance for power cable OLPD testing.
