Devices type VLD-O are used in normal operation, i.e. they limit increased touch voltage caused by the rail potential during the train operation. The function of voltage limiting devices is not the protection against lightning and switching surges. This protection is provided by Surge Protective Devices (SPD).
Long term exposure to lower level transient over-voltages can also lead to premature ageing of equipment. Havells offers a comprehensive range of Surge Different type of surge protection devices are used according to the different network systems; therefore it is very important to ensure that surge protection device is Type of protection. Surge protective devices. (SPD) for electrical power supply networks. Power frequency overvoltage protectors (POP) for electrical.

It is the wire carried the line supports and runs over the phase conductors. The purpose of the earth wire is to block the direct lightning strokes, which would otherwise strike the phase conductors.
The early under voltage protection circuit constructed consisted of a single transistor (PNP) and a
Siemens Industry Catalog - Energy - Low-voltage - Power distribution - Low-voltage components - SENTRON Protection, Switching, Measuring and Monitoring Devices - Overvoltage Protection Devices
Overvoltage protection devices serve to protect valuable plants and equipment and prevent financial losses arising from equipment failures SENTRON overvoltage protection devices protect your plants and equipment against failures. Overvoltage protection is a characteristic of a power supply system, which somehow deals with the voltage across the load side when the input voltage exceeds the pre-set value. In some situations where the input voltage is higher than expected, we always use an overvoltage protection or crowbar protection circuit.

Measuring relays and protection equipment - Part 127: Functional requirements for over/under voltage protection. Ansvarig kommitté: IEC TC 95 - Measuring
Thyristors: They are crowbar devices used as surge protective devices. They are based on pair of intertwined bipolar transistors … By adding a little extra protection circuitry in the form of over-voltage protection, it is possible to protect against this unlikely but catastrophic possibility. Most power supplies designed for very reliable operation of high value equipment will incorporate some form of over-voltage protection to ensure that any power supply failure does not result in damage to the equipment being powered.
