'alstom' Protection Relay

Overview

The three-phase microcomputer relay control tester has a 4-phase voltage 3 phase current output, which is suitable for various types of relay protection devices. The microcomputer relay control tester uses a high-speed high-performance digital signal processor comparative speed, transmission frequency bandwidth, and software application bifurcation algorithm produces each of the respective high-precision waveforms. Due to the integrated structure, each part is closely coupled, the data transmission distance is short, and the structure is compact.

GE TRANSFORMER PROTECTION RELAY
The T60 Transformer Protection System is part of the Universal Relay (UR) series of products. It is a microprocessor-based
relay for protection of small, medium, and large three-phase power transformers. The relay can be configured for a
maximum of six three-phase current inputs and six ground current inputs, and can satisfy applications with transformer
windings connected between two breakers, such as in a ring bus or in breaker-and-a-half configurations. The T60
performs magnitude and phase shift compensation internally, eliminating requirements for external CT connections and
auxiliary CTs.

Fuji Electric's UPS and power solutions have the best product specifications with the latest technology. Fuji's products are available in the 72 VA to 2000 kVA range, for single modules. For higher ratings, these can be paralleled to deliver 12000 kVA. Fuji Electric's high efficiency UPS helps in reducing costs, weight, footprint and heat.
