Hariff Daya Tunggal Engineering makes available an energy logger to monitor potential disruptions to transformer systems as and when they happen. This monitoring tool emits an alarm with the substation ID number to identify the site of the disturbance and relays this information real-time to a centralized management center. Often installed in tandem with Hariff’s comprehensive Site Monitoring System, the Energy Logger ensures that technicians are able to address interference within the transformer system at the earliest signs of trouble, therefore limiting the possibility for costly damage and extended downtime.
