Protection relays and systems are critical components in keeping electrical and power applications safe and efficient. The SE-330HV-23-01 is a multi-functional digital, intelligent, zero-sequence electronic earth leakage protector with a reverse-phase sequence multi-trip protection function. It is designed for the protection of metal-cased three-phase air-insulated and insulated busbars, as well as single-motors, high-low voltage transformers, generator sets, and other electrical equipment.

The SE-330HV-23-01 has a built-in protection, control, measuring, and adjustment functions, making it a comprehensive multi-functional protective product. It can detect over-voltage, under-voltage, zero-sequence current, unbalanced load, single-phase current, zero-phase fault current, and reverse-phase sequence multi-trip protection. It also added up to 8 digital input points and 15 digital output points, allowing the user to connect other devices to extend functions such as CT scanning, alarm, communication transmission, etc.

The SE-330HV-23-01 is widely used in medium and low pressure power systems in various industries such as metallurgy, petrochemical, electricity, coal, construction, environmental engineering, etc. It is used to detect the following events: high-temperature, fire, melting busbar, over-current, zero-sequence current, unbalanced load, reverse-power frequency, single-phase grounding fault, zero-phase fault current, reverse-phase sequence multi-trip protection, and so on. For these events, the SE-330HV-23-01 initiates protection operations and measures to protect the equipment.

The SE-330HV-23-01 uses an advanced digital signal processor (DSP) which controls all related protection and control functions. This processor allows for fast signal sensing and protection action. The DSP also stores the protection settings such as time delay, current setting, and other parameters. This allows for easy system management and removal of any human errors.

The SE-330HV-23-01 features a unique reverse-phase sequence multi-trip protection component. This component is used to detect three-phase reverse-phase sequence currents and trip the circuit breaker when the three-phase currents reach certain levels. The threshold can be set according to the user requirements, thus ensuring the safety and efficient functioning of your system.

The SE-330HV-23-01 offers enhanced measurement capabilities such as current, voltage, power, and harmonic factor calculation. It can be used to measure the following data points: current, voltage, power, pressure, temperature, light, humidity, vibration, and so on. This is important for many operations that use high-voltage and low-voltage equipment.

The SE-330HV-23-01 offers advanced communication functions. The system is compatible with various communication protocols such as MODBUS-RTU, PROFIBUS-DP, and DeviceNet. This allows for remote control and monitoring of the system. The SE-330HV-23-01 is an ideal solution for effective system protection.
