Protection relays and systems play an important role in the efficient operation and safety of electrical power systems. The WCT3-26DC-1SX-B/03 is an electronic protection relay designed for transformer neutral overcurrent and earth fault protection. This article takes a look at the application field and working principle of this protection relay.

The WCT3-26DC-1SX-B/03 is a transformer protection relay with three-phase earth fault protection. It is designed to be used as a main relay in medium-voltage power systems. With its high reliability, stability, and accuracy, it can provide protection against multiple operating faults, such as transformer neutral overcurrent and earth fault. It can also detect insulation abnormalities, such as local and general faults.

The WCT3-26DC-1SX-B/03’s application field includes medium-voltage power systems such as substations, power plants, distribution systems, and process industries. In addition, it is also suitable for use in applications such as load monitoring, energy management, and demand shedding. It has an extended operating temperature range of -40°C to +60°C and a wide operating voltage range of 0-1000Vac/dc.

The WCT3-26DC-1SX-B/03 is an electronic protection relay based on microprocessor technology. It features two relays, a three-phase trip relay, and a single-phase trip relay. The three-phase trip relay can detect phase-to-phase, phase-to-ground, and phase-to-neutral faults. The single-phase trip relay is designed for neutral overcurrent protection, general earth fault protection, and individual earth fault protection. It also has an adjustable time delay, which can be set according to the system requirements.

The WCT3-26DC-1SX-B/03 works by monitoring the input voltage and current signals from the transformer. When a fault is detected, it will actuate the trip relays to disconnect the transformer from the system. The relay also features transformer differential protection capabilities. If the local and general faults are different from the preset thresholds, the relay will immediately trip the transformer.

The WCT3-26DC-1SX-B/03 is an effective protection relay for transformer neutral overcurrent and earth fault protection. It is suitable for a variety of applications, such as power plants, distribution systems, and process industries. It features extended operating temperature and voltage ranges as well as its advanced microprocessor technology. With its reliable and accurate operation, it can ensure the safe operation of your power system.
