During fault, the only circuit breaker closest to the fault point should be tripped. The operating time of relay associated with protection of line should be as minimum as possible in order to prevent unnecessary tripping of circuit breakers associated with other healthy parts of power system.

Max Reverse Leakage Current refers to the maximum amount of current that can flow through a semiconductor device, such as a diode or transistor, when it is reverse biased. This current is an important parameter as it indicates the level of unintended current that can flow when the device is not conducting in the forward direction. High values of reverse leakage current can lead to power loss, reduced efficiency, and may affect the performance and reliability of electronic circuits. It is particularly critical in applications where precise current control and low power consumption are necessary.

Clamping voltage is a term used in electronic components, particularly in devices like diodes and transient voltage suppressors. It refers to the maximum voltage level at which the component can effectively limit or clamp the voltage across its terminals. When the voltage across the component exceeds the clamping voltage, the component conducts and effectively limits the voltage to that level, protecting the circuit from overvoltage conditions. Clamping voltage is an important parameter to consider when selecting components for applications where voltage spikes or surges may occur, as it determines the level at which the component will start to protect the circuit.

The peak pulse power rating of a TVS diode is defined as the instantaneous power dissipated by a device for a given pulse condition, and is a measure of the power that is dissipated in the TVS junction during a given transient event.

Surge current is a peak non repetitive current. Maximum (peak or surge) forward current = IFSM or if(surge), the maximum peak amount of current the diode is able to conduct in forward bias mode.

Peak Pulse Power is a parameter used to specify the maximum amount of power that an electronic component can handle during a transient event, such as a surge or spike in voltage or current. It indicates the maximum power dissipation capability of the component for a short duration. This parameter is important for protecting electronic circuits from damage caused by sudden high-energy events. Peak Pulse Power is typically expressed in watts and is crucial for selecting components that can withstand transient overloads without failing. It helps ensure the reliability and longevity of electronic systems in various applications.

In electronic components, the parameter "Direction" refers to the orientation or alignment in which the component is designed to operate effectively. This parameter is particularly important for components such as diodes, transistors, and capacitors, which have specific polarity or orientation requirements for proper functionality. For example, diodes allow current flow in one direction only, so their direction parameter indicates the correct orientation for current flow. Similarly, polarized capacitors have a positive and negative terminal, requiring proper alignment for correct operation. Understanding and adhering to the direction parameter is crucial for ensuring the reliable and efficient performance of electronic components in a circuit.

Test Current refers to a specified amount of electrical current applied to an electronic component during testing to evaluate its performance and characteristics. This current is typically defined by manufacturers to ensure that the component operates within its designed parameters. By measuring how the component reacts to this test current, engineers can determine its reliability, efficiency, and suitability for specific applications.

Reverse Breakdown Voltage is the maximum reverse voltage a semiconductor device can withstand before it starts to conduct heavily in the reverse direction. It is a critical parameter in diodes and other components, indicating the threshold at which the material's insulating properties fail. Beyond this voltage, the device may enter a breakdown region, leading to potential damage if not properly managed. This parameter is essential for ensuring safe operation and reliability in electronic circuits.

Max Forward Surge Current (Ifsm) is a parameter used to specify the maximum peak current that a diode or other electronic component can withstand for a short duration during a surge event. Surge currents can occur due to sudden changes in voltage or power supply fluctuations, and the Ifsm rating helps determine the component's ability to handle such transient overloads without being damaged. It is important to consider the Ifsm rating when selecting components for applications where surge currents are expected, such as in power supplies, motor drives, and other high-power circuits. Exceeding the Ifsm rating can lead to overheating, degradation, or failure of the component, so it is crucial to ensure that the chosen component can safely handle the expected surge currents in the circuit.

Min Breakdown Voltage is the minimum voltage at which an electronic component, typically a diode or transistor, begins to conduct electricity in the reverse direction.
