T501; Real-time transformer monitoring device
T501
T501is a multi-channel data recording system for a wide range of analog and digital sensors/signals.
T501 can monitor the following transformer parameters:
- Transformer oil temperature
- Ambient temperature
- Load current
- Oil level indication
- Cooling system status (fans/pumps)
- Winding hot-spot temperature
- Average winding temperature
- Transformer ageing and loss of life
- Overload capacity
- Cooling control and fan bank exercise
The transformer monitoring system, T501, is designed to monitor the evaluation of essential transformer condition parameters, with the flexibility to use the following input signals/sensors:
- Up to 6 analog inputs with the combination of: RTD, potentiometer, CT, 4-20mA and VT inputs
- Up to 2 digital inputs for binary signals from transformers, e.g. fan/pump status
- Up to 24 fiber optic channels for temperature measurement of winding hot-spots
- Up to 8 programmable analog outputs (4-20mA or 0-5/10V) to send data to third-party systems
- Up to 8 relay outputs (Form C relays) to send an alarm signal to third-party systems
- Different communication options, e.g. serial (RS485), Ethernet (RJ-45) and fiber optic (SFP) ports
The T501 is a panel-mount unit that can be easily installed in the transformer control enclosure. The monitor is easily configured with the integrated software, Rugged Connect and web-client. Rugged Connect is a Windows-based software for data collection, analysis, visualisation and reporting. The T501 also comes with a web client that allows remote viewing, configuration and reporting via a web browser.
In addition, T501 can also send data to customer data loggers using the following protocols, which are supplied as an option separately with the unit:
- Serial protocols: Modbus, DNP3.0, IEC 60870-5-101
- Ethernet protocols (TCP / IP): Modbus, DNP3.0, IEC 60870-5-104, IEC61850
The T501 can also be integrated with other advanced sensors on the transformer, e.g. Dissolved Gas Analysers (DGAs), Partial Discharge Monitors (PDs), bushing monitors, and others. Integration with third-party monitoring systems can be done using standard communication protocols such as Modbus and DNP3.0.
