ABOUT TROJAN DRY-OUT SYSTEMS
Portable systems for analysing the insulating oil and removing water from the cellulose.
Analysis / Dry-Out Systems — Technical Description
Fully automated, for safe online connection to the transformer main tank, trailer or trolley mounted they provide reliable, long term unattended analysis, degassing and water in cellulose reduction.
The water in oil Sensor provides real time data and allows accurate water in cellulose diagnosis before, during and after water removal. The operator programs the PLC to automatically Re-Dry the large capacity filters after a certain number of hours. This filtering – re-drying continues until the Trojan is stopped. By regularly Re-Drying the Filters, water removal efficiency is significantly improved, which creates a strong disequilibrium between the oil and cellulose (Trojan Examples). The Filters last over 18 months giving low cost water reduction.
Data is logged to memory and available onsite by laptop and by dial up GSM Modem (software supplied). Our ongoing services include analysis interpretation - diagnosis, ongoing monitoring and transformer fleet water reduction management. If you only want to move the Trojan between transformers, we can provide the rest. Utilities find them very easy to use. Virtually no maintenance is required, and the many safety features automatically shut down and make safe during faults.
Trojan Sensor — Fixed location Analysis
Available late 2007
Read the insulating oil temperature – relative saturation – water in oil ppm.
24v input – analogue outputs – Sensor can be inserted directly into oil through a valve.
Trojan Sensor – Portable Online Analysis System
Available late 2007
Records to memory – oil temperature - relative saturation – water in oil ppm - date – time.
Mains + battery – data memory 30 days – data access by laptop or remote GSM dial up.
Two lightweight rugged weatherproof models are available.
- Sensor directly inserted into the oil in the transformer through a valve, or
- Pump and hoses draw the oil to the sensor and then returns the oil to the transformer.
