Description

Designed for a two-winding transformer scheme, the GE Multilin 745-W2-P5-G5-HI-A-L-R-E-H combines primary protection and management in a draw-out relay. The selected hardware includes five-ampere current inputs and high-range control power. Its configured analog interface supports integration with external measurement and monitoring circuits. Loss-of-life and restricted ground-fault options extend the application beyond basic overcurrent detection. Programmable logic coordinates the protection scheme with the transformer control arrangement. The enhanced local display and harsh-environment coating complete the identified configuration.

04

Transformer Protection and Asset Monitoring

Transformer measurements→Protection and thermal model→Control and condition information
Two-winding coordination

The configured winding input arrangement supports protection coordination across the transformer sides.

Loss-of-life assessment

The L option supplies transformer aging information using the supported thermal and insulation-aging functions.

Custom control logic
FlexLogic allows protection and control signals to be combined for the selected transformer application.
05

Two-Winding Transformer Management

Primary and backup coverage

Combine differential, overcurrent and selected ground-fault functions for the engineered transformer scheme.

Asset and substation information

Use the configured analog interfaces and monitoring functions within the wider transformer management arrangement.

The relay uses a draw-out case with automatic CT shorting. Follow the correct removal and installation procedure for the energized-current circuit arrangement.

Professional Team

Nearly 10 Years of Industry Experience

Our team members have an average of more than 10 years of industry experience. We have worked with customers worldwide, including those from India, Germany, Sweden, Italy, Russia, Venezuela, Israel, and many other countries. Throughout our careers, we have collectively completed over 3,000 orders and established long-term business relationships with customers across nearly 30 countries.

Professional Product Judgment

We can often identify a product’s manufacturer, series, configuration, and function from its model number or nameplate photo. We also understand how revisions, firmware, and specifications affect compatibility and whether an alternative model can be used safely.

In Practice: An Indian customer urgently needed a discontinued control module after several suppliers reported no stock. We identified its exact revision and function from the nameplate, checked compatible alternatives, and contacted factory and warehouse channels to locate matching inventory. After installation, the customer confirmed that the module operated correctly and later asked us to source additional spare parts.

Sincere and Patient Service

Our team treats every inquiry sincerely and answers every question patiently. Even for complex requests, we verify and respond to each detail instead of providing a rushed or uncertain answer.

In Practice: A German customer sent a mixed list of automation products and asked repeated questions about revisions, condition, photos, and delivery. Our team organized the requirements, checked every item, and replied point by point. The customer said our detailed communication made the purchasing decision easier and continued sending us new inquiries.

Transaction Cases

Sincere Cooperation, Long-Term Trust

Germany
Germany – A Germany customer urgently needed a replacement for a discontinued automation component. After reviewing the product label, technical parameters, and application details, our engineers recommended a compatible alternative and provided photos and test videos before shipment. The alternative performed well, enhancing the customer's confidence in our technical capabilities and leading to multiple repeat orders.
India

India – An Indian customer still had doubts after initial online communication with us, so they visited our company in person for a face-to-face meeting and product inspection. This visit increased the customer's trust and led to the successful placement of their first order. Over the next few years, we completed multiple orders and established a stable, long-term partnership.

Malaysia

Malaysia – A Malaysia customer needed a specific automation component and compared products and services from several suppliers online. After nearly three weeks of careful consideration, our sincere communication, professional service, and reliable product quality won the customer's trust. After receiving the product and using it for several weeks without any problems, the customer gave us positive feedback and subsequently placed multiple orders.
