Techimp HQ S.r.L
Smart Sensorgrid belongs to the smart sensor family devised for on-line monitoring of diagnostic quantities in electrical assets. It provides traffic-light alerts to SCADA systems / asset and maintenance service. Smart Sensorgrid is a state-of-art PD analyzer, exploiting the TECHIMP T-F Map technology (patented). Such feature allows noise rejection and automatic alarm warning based on amplitude and repetition rate trend relevant to statistical parameters. The PD sensor, a HFCT, is integrated in the smart sensor body.

3i -
Scope T&M Pvt, Ltd.
The portable multipurpose 3i device (Intellectual Insulation Indicator) is for eff ective high-voltage equipment insulation monitoring on-line. The 3i device measures and analyses partial discharges (PD). For eff ective PD measurement and noise rejection, there are two types of sensors used in the device: the acoustic sensor and the TEV sensor. Both the sensors are built into the device case, and so do not need any connection cables. The device is supplied in a strong metal case; at the faceplate there are the colored screen and two buttons: power button and function button.

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).
