About the 745-W2-P5-G5-HI-T
The 745-W2-P5-G5-HI-T is from the 745 Transformer Protection System series. These relays were manufactured by General Electric Multilin. The 745-W2-P5-G5-HI-T is able to protect small, medium, and larger power transformers, autotransformers, and reactors.
The 745-W2-P5-G5-HI-T has a number of combined protective features. Some of these protective features are:
- Overcurrent
- Percent differential
- Overexcitation
- Under/overfrequency
The 745-W2-P5-G5-HI-T also has metering and monitoring capabilities. The built-in metering function eliminates the needs for operators to have a separate metering device, which reduces cost and clutter of a workspace. The 745-W2-P5-G5-HI-T can monitor individual harmonics and total harmonic distortion.
The 745-W2-P5-G5-HI-T also has multiple setpoint groups that allow users to select groups of relay settings to address the protection requirements of different power system configurations. The 745-W2-P5-G5-HI-T has LEDs that indicate status of the relay and system. These LEDs will also alert users to any alarm or fault conditions.
