One of the tasks of wide area monitoring system is thermal line monitoring. Since power transformers are also including in wide area systems, WAProtectorTM enables real-time thermal monitoring of power transformers. |
Transformer-monitoring module enables transformer operation closer to its limits. The module allows getting more out of exiting transformer and permitting operation at higher capacity factors to reach the maximum economical efficiency. |
|
The transformer-monitoring module for overload management is defined by the
IEEE (C57.91-1995/Cor 1/ July, 2001) and IEC 60354 (IEC, 1991) loading guides. |
With information from the top-oil, ambient temperature, current and voltage
inputs, the transformer-monitoring module is able to provide unique asset management functionality. This
functionality includes overload tracking with the temperature (adaptive overload), automated load shedding
based on temperature and/or current levels and predictive overload early warning. Combined with loss of
life estimation, the transformer-monitoring module provides protection, monitoring and control for the
transformer in one integrated unit.

Data acquisition drivers |
WAProtectorTM enables direct data acquisition from Hydran® M2 and Hydran® 201i system.
|
Monitoring values |
A wide range of different measurements can be acquired for
monitoring of power transformer. Depends on the size of transformer, its role and importance in the
network as well as condition, the following variables can be measured: |
|
|
|
|
|
|
|
- On-load tap changer position
|
|
|
- Protective relay statuses
|
All monitoring values are stored in permanent database.
