 The PD Annunciator™ unique design consists of a three channels acquisition module paired with sensors of your choice, most commonly TEV and Acoustic or HFCT. With many advancements and innovations, the PD Annunciator™ handles partial discharge monitoring on metallic cabinets using our proven and advanced technologies. 

 The SonoTEV™ sensor has built-in TEV (transient earth voltages) and contact ultrasonic sensors for partial discharge detection on metal clad cabinets.

Part number: SonoTEV

The SonoTEV Air™ sensor has built-in TEV (transient earth voltages) and airborne ultrasonic sensors for partial discharge detection on metal clad cabinets.

Part number: SonoTEV-Air

 The SonoTEVi-Air™ sensor has built-in TEV (transient earth voltages) and airborne ultrasonic sensors for partial discharge detection on metal clad cabinets. It design is suited for installation inside the metal-clad cabinet.

Part number: SonoTEVi-Air

 The HFCT-20HD™ sensor is a high frequency current transformer sensor designed for partial discharge activity detection.

Part number: HFCT-20HD

The HFCT-60HD™ sensor is a high frequency current transformer sensor designed for partial discharge activity detection.

Part number: HFCT-60HD

PD-SIM™ is a partial discharge simulator used to test the integrity of a PD Annunciator system by testing it’s SonoTEV™ or HFCT-HD sensors.

Part number: PD-SIM

PDA-Cloud™ is a global solution for the remote access and alarm management from PD Annunciator™ modules. These newly developed features allow for reliable cellular communication in most countries, data analysis through its web-based interface, data export, alarm management and much more.

Part number: PDA-Cloud

The AE-150™ is designed to detect and localize Partial Discharge activity by correlating acoustic and electric sensors’ data. The AE-150™ has many acquisition modes, each used for detecting and locating Partial Discharge activity in a transformer. The AE-150™ unit is mounted on the transformer tank using its powerful magnets that also hold four acoustic sensors. Acquired data is sent to Mirador-Tx software where all advanced positioning functions are implemented. This cutting-edge software allows easy data interpretation, reporting and monitoring.

 The well-established XDP-II™ is a battery-operated portable device allowing partial discharge detection and analysis. The data is saved in its internal memory for local or further analysis on the PC-based XDP-SOFT™. Paired with the proper accessories, the XDP-II™ becomes a powerful solution for many applications such as Cable Joints and Elbows, Switchgear, Offline, Acoustic, TEV, Rotating machines, Transformer, etc…
