PD Annunciator - Partial Discharge Alarm System

Description

The PD AnnunciatorTM unique design consists of a three channels acquisition module paired with sensors of your choice, most commonly TEV and Acoustic or HFCT.

The PC AnnunciatorTM handles partial discharge monitoring on metallic cabinets using NDB’s proven and advanced technologies.

The module is equipped with fast VHF/UHF PD detection circuitry, that TEV type measurements take advantage of. It also has a highly sensitive ultrasonic detection circuitry yielding efficient results. Modbus communication allows for easy integration with existing Scada system over RS485 standard.

Features

- TEV, Acoustic, and HFCT sensor technologies.

- Easy to install.

- Intuitive software.

- Modbus connectivity.

- Local USB connectivity.

- Single or multi-module installation.

SonoTEV Sensor

The SonoTEVTM sensor is installed directly on the cabinet metallic surface. Its unique design allows for VHF signals detection produced by partial discharge activity within the cabinet enclosure using a capacitive coupling technology. The SonoTEVTM sensor is also equipped with a contact ultrasonic sensor that targets acoustic PC signals. Its aluminum body case allows for great immunity to nearby electrical noise sources for greater sensitivity.
