About the 745-W2-P1-G1-LO-E

General Electric Multilin 745-W2-P1-G1-LO-E Transformer Protection System

  • Configurable and Versatile: This model is a highly configurable Transformer Protection System from the GE Multilin 745 series. Its FlexLogic™ technology works with setpoint capabilities to allow for versatile, system-specific programming.
  • General Management Features: It offers essential transformer management, including:
    • Underfrequency and overfrequency protection
    • Transformer overload protection
    • CT correction factors
    • And more.

Chassis and Monitoring

  • Durable Chassis: The device is housed in a 745 SR Series chassis, which protects the relay during drawout operations and helps prevent dust entry.
  • Visual Indicators: A glass front on the chassis allows users to monitor LEDs on the front panel. These LEDs indicate system statuses and alert users to errors, using green, amber, or solid red lights for easy reference of system health.

Environmental Operation and Protection

  • Operating Conditions: The relay functions reliably in temperatures from -40°F to +140°F, humidity up to 90% non-condensing, and altitudes up to 2000m. Operating outside these parameters can cause system damage over time.
  • Optional Conformal Coating: An optional conformal coating (not included on this version) can provide enhanced protection against dust, humidity, harsh temperatures, and chemical corrosion. Buyers can choose a model with this coating or request AX Control to add it.

Frequently Asked Questions about 745-W2-P1-G1-LO-E

What specifications apply to the ethernet for the 745-W2-P1-G1-Lo-E Multilin option?
Actually the E does not stand for Ethernet. The E indicates that the 745-W2-P1-G1-Lo-E Multilin includes the enhanced display option with the larger LCD. For a transformer protection system to come with the Ethernet the part number must indicate a T, as opposed to an E. In that case, the transformer management relay would have an ethernet with a 10Base-T RJ45 connector. The ethernet would be Version 2.0 / IEEE 802.3 and with a Modbus TCP/IP. 
How does the 745-W2-P1-G1-Lo-E Multilin address false tripping during inrush?
The 745-W2-P1-G1-Lo-E Multilin has many adaptive features that make it a great transformer protection system with regard to protection and management of various size power transformers. It can monitor both individual and total harmonic distortion in one relay management system. Specific to your question, it addresses false tripping during inrush with adaptive harmonic restraint. It can also adjust the pickup setting of adaptive time overcurrent elements in the event that load currents need to be supplied with a content that is highly harmonic.
How low is the control power for this transformer protection 745-W2-P1-G1-Lo-E Multilin?
The control power includes a range from 20 to 60 DC (volt), AC 20 to 48 (volt), with 48-62 Hertz. This range is for a transformer protection system with a low control power as is the 745-W2-P1-G1-Lo-E Multilin.
