UltraTEV Alarm

UltraTEV Alarm™ is a simple alarm system. It warns you of suspected or actual partial discharge activity before it leads to failures.

Global leader in the market, it emits a visual and audible alarm when a problem occurs to notify staff of a technical failure. This device also sends an alarm signal directly to the SCADA system or to an EA TECHNOLOGY host server via the GSM network.

Using third-party software, UltraTEV Alarm sends an email or text message when a fault arises.

Simple to install and easy to use, UltraTEV Alarm monitors your installations 24 hours a day. This reliable system makes maintenance easier.
