The 131425-1 is a complete suite of electronic overcurrent relays that can be designed for a variety of industrial and commercial applications. It performs various electrical functions and is capable of detecting and providing protection against various electrical conditions. The module provides protection against overcurrent, undercurrent, phase unbalance, overvoltage, undervoltage, frequency, and lockout conditions.

Application Field: 131425-1 is designed for a variety of industrial and commercial applications such as lightly loaded motors, transformer overcurrent protection, wiring and cable protection, generator overcurrent protection, overprotection and protection against deleted connections, etc. The 131425-1 is also designed for special applications such as single line grounding, stabilized system operation, overload coordination for synchronous motors, coordination for other types of protective device, etc. This module can be used for monitoring and protecting motors, circuits, and cables.

Working Principle: 131425-1 employs advanced electronic sensors for detecting and measuring current, voltage, and frequency. The module applies static logic or microprocessor-based logic to compute, analyze, and compare values of current, voltage, and frequency to determine if there is an abnormal situation or an overcurrent condition. If an overcurrent condition is detected, the module trips to provide protection and then resets when the fault has been removed.

The 131425-1 module comprises of several components which are responsible for monitoring and detecting electrical conditions. Primary components which comprise the electronic relay include current transformers, voltage transformers, current sensors, voltage sensors, frequency sensors, and microprocessor logic. The current and voltage transformers are used to reduce and maintain a uniform level of current and voltage within specified ranges. The sensor components are used to detect and measure the various electrical conditions and are connected to a comparator which determines the difference between actual and desired values. If the difference is found to exceed the predetermined tolerance levels then it is considered an anomaly.

The sensors which are responsible for detecting and measuring electrical conditions also have the capability to analyze the waveforms related to the conditions for further evaluation. The sensors use a combination of algorithms and logic to identify various conditions and also detect the disturbances in the electrical system. In the case of overcurrent, the module can detect the peak current and trip the relay to provide protection. The module resets after the fault has been removed.

131425-1 also includes an internal lockout function which is activated when the electrical conditions are detected as hazardous or potentially dangerous. This helps to prevent any further catastrophic failure of the system. The lockout function also ensures that when the protections systems are overloaded or critically damaged; it will disconnect the load until appropriate measures are taken. In addition, the system is capable of displaying various indications and alarms which can notify the user of any kind of electrical disturbance or fault condition.

The 131425-1 relay is a reliable and secure system that is used in many industrial applications and is also capable of providing multiple levels of protection. This system can be used to detect and protect against various kinds of electrical overcurrent conditions, as well as provide an indication or alarm when needed. The system is designed to provide an efficient and reliable protection system against any kind of possible disturbance or fault in the electrical system.
