The transformer protection
T-PRO relay provides complete transformer fault
protection, overload protection, fault oscillography
& transformer monitoring with one integrated
technology.
Five sets of CT inputs for differential protection
(15 in total).
Software control adjusts current magnitude &
angle.
Asset management to maximize use of transformer
capacity (ANSI/IEEE C57.91-1995).
High quality recording
- fault recording (96 samples/cycle), trending
& event logging.
Easy to use, simplified relay setting & record
analysis software (Windows 9x/ME/NT/2000) included.
Intuitive ASCII-terminal
interface provides full local or
remote access.
Substation automation ready.
The T-PRO Transformer
Protection Relay provides the following features:
Protection functions include IEEE devices 87,
87N, 49, 50/51, 50N/51N, 59FI/59FT, 59N, 60, 67,
81, THD, Temperature Control & TOEWS.
Optimize transformer loading:
* adaptive overload
* auto-adjust overload characteristics based
on temperature
* controlled load shedding
* 30 day load trend
* transformer overload early warning system
(TOEWS ©), new Application
Note (PDF, 35Kb).
* predictive 15 & 30 minute alarms
* ProLogic
- control logic statements.
Three communication RS-232 ports. Internal modem
option.
Direct-connect DNP3 & Modbus SCADA communication
protocols (Ethernet ready).
IRIG-B time stamping & sample synchronization.
