Product Overview

ABB HIEE205010R0003 UNS 3020A-Z, V3 Ground Fault Relay is a high-performance equipment designed specifically for industrial applications, playing a critical role in ensuring the safe operation of electrical systems. Its design aims to accurately detect grounding faults in the system, avoid safety accidents and equipment damage caused by leakage, and build a solid safety defense line for the stable development of various industrial production activities.


Core functions

Grounding fault detection: With a highly sensitive detection mechanism, it can quickly and accurately identify grounding faults in electrical systems, even extremely small leakage currents can be detected in a timely manner, effectively avoiding the expansion of faults.

Fault alarm: Once a grounding fault is detected, the relay will immediately trigger an alarm signal, notify the operator in a timely manner through indicator light flashing, electrical signal output, etc., so as to take prompt response measures.

Circuit protection: Upon detecting a fault, quickly cut off the faulty circuit to prevent excessive fault current from causing damage to equipment and personnel, and protect the overall safety of the electrical system.


Working principle

The grounding fault relay mainly operates based on the principle of residual current detection. In normal operation, the vector sum of the currents in each phase of the electrical system is zero. When a grounding fault occurs in the system, residual current will be generated, that is, the sum of the current vectors of each phase is no longer zero. The current transformer inside HIEE205010R0003 will detect this residual current and convert it into an electrical signal to be transmitted to the core control unit of the relay. The control unit analyzes and processes the received signal. When the residual current exceeds the preset threshold, the control unit will issue instructions to drive the contact of the relay to act, thereby achieving the functions of alarm and cutting off the fault circuit.


Key advantages

High sensitivity and reliability: able to accurately detect small grounding faults, operate stably and reliably, with very few false alarms or missed alarms, providing a solid guarantee for electrical system safety.

Wide working range: It can work normally within a wide range of voltage, current, and temperature, with strong adaptability, and can meet the complex application requirements of different industrial environments.

Easy to install and integrate: The compact design makes the installation process simple and can seamlessly integrate with various existing electrical control systems without causing too many changes to the original system architecture.

Long service life: Made of high-quality materials and advanced manufacturing processes, it has excellent durability and can maintain stable performance during long-term use, reducing maintenance costs and equipment replacement frequency.


Precautions

Installation environment: It should be installed in a dry, well ventilated, and non corrosive gas environment, avoiding high temperature, high humidity, and strong electromagnetic interference to ensure the normal operation of the relay.

Wiring specifications: Strictly follow the wiring diagram in the product manual to ensure secure and correct wiring, and prevent relay misoperation or damage caused by wiring errors.

Regular maintenance: Regularly inspect and maintain the relay, including cleaning the housing, checking the contact status, testing performance, etc., promptly identify potential problems and solve them to ensure its long-term stable operation.

Parameter setting: According to the actual requirements of the electrical system, set the protection sensitivity and other parameters of the relay reasonably to avoid improper parameter settings affecting its protection effect.


Similar model supplement

UNS 3020A-Z, V1: It is an early version of HIEE205010R0003, which is similar in functionality to V3 version, but V3 has improved detection accuracy and response speed. In some application scenarios, V1 may have relatively lower costs and is suitable for situations where performance requirements are not particularly high.

UNS 2880B-P V2: focuses on grounding protection for specific electrical systems, and differs from HIEE205010R0003 in terms of rated current and voltage parameters. It is suitable for industrial equipment or small electrical systems with special requirements for current and voltage specifications.
