Signature service

Monitor power qualityin real time

The Signature service analyzes and diagnoses power quality using Hydro-Québec–supplied equipment that provides continuous measurement at your company’s supply point. Any load loss resulting from an electrical disturbance or power failure is detected in real time and you are automatically notified by e-mail or cell phone.

You’ll also receive a power quality report by e-mail weekly. The Signature service provides direct, exclusive access to Hydro-Québec experts who will help improve your electrical installation.

«When a power transformer blew, the analysis provided by the Signature service helped us reach a fast settlement under the manufacturer’s warranty. »

Analysis of a disturbance could lead to making equipment less sensitive so the same thing doesn’t happen again.
