D IG ITA L DRY TR A NS FOR M ER 1 Safety Overview Full compliance with all general safety requirements must be observed during system installation and operation. Read this guide thoroughly before using the system and make sure that you thoroughly understand its contents before installing, using or maintaining the system.
D IG ITA L DRY TR A NS FOR M ER • • • • Do not, under any circumstances, remove the warning and caution labels. Information must be available at all times for the security of the user. If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. The instrument is intended for factory and field installation by qualified service personnel according to manufacturer’s installation instructions and local/national wiring requirements.
D IG ITA L DRY TR A NS FOR M ER 2 TXpert Module Overview The TXpert module is an integrated component of the TXpertTM Digital Dry Transformer. This module integrates sensors and electronics to gather data, perform calculations, and provide analytics of key performance indicators. Data may be downloaded from the TXpert by Wi-Fi or ethernet communication with a host computer running a WebUI or by sending push communication messages to a MQTT (Message Queuing Telemetry Transport) client.
D IG ITA L DRY TR A NS FOR M ER 2.1.1 Measurement and Control Connections The TXpert uses custom cabling to communicate with sensors and modules. When a connector is not in use, it should be kept covered with the provided, protective cap.
D IG ITA L DRY TR A NS FOR M ER Cabling should not be added or removed when voltage is applied to the transformer. 2.1.2 Sensor and Power Readings 2.1.2.1 Power Readings Voltage is measured on each of the three phases via cables attached to the neutral and low voltage bushings. Current measurements are read from Rogowski coils mounted to encircle the low voltage bushings.
D IG ITA L DRY TR A NS FOR M ER 2.2 Communications Module The Communications Module is the Wi-Fi hotspot and is installed outside of any metallic enclosure (for easier accessibility and to allow connectivity). As a security precaution, an ABB-supplied NFC/RFID card must be detected to enable the Wi-Fi. The communications module is equipped with a GPS device that detects the transformer location and maintains an accurate system clock. The typical range of TXpert Wi-Fi communications is 50 to 92 meters.
D IG ITA L DRY TR A NS FOR M ER 3 Setting up Your MS WindowsTM-based Laptop or Tablet for TXpert WebUI Communication The TXpert communicates to your laptop or tablet via Wi-Fi or Ethernet. A web server interface allows you to view the TXpert sensor readings, calculated values, warnings and events, and transformer characteristics.

D IG ITA L DRY TR A NS FOR M ER 4 Accessing the TXpert User Interface You may access the TXpert user interface via a wired Ethernet connection or Wi-Fi. Wi-Fi communication is initiated when the TXpert Communications Module recognizes a programmed NFC card. This triggers the Wi-Fi connection to be exposed to laptops or tablets with a valid security certificate. The Wi-Fi connection will automatically terminate if no communication is detected for 16 minutes.
