What is the use of fault passage indicator?

CSFPI, Fault Passage Indicator — Earth is designed to detect and indicate Earth fault on a cable system, in RMU networks with one input / open ring arrangement. The unit will indicate a fault condition when current is detected above set trip current settings.

What does an indicator do in a circuit?

An indicator light is mainly used on the circuit or mechanical equipment to monitor and alarm the operation status of the equipment.

What is used as indicator in electronic equipment?

In general, a digital indicator has been designed to display the symbol and digital information in the electronic devices and equipment. There are several ways to display the data of a digital meter, ranging from a simple neon lamp to the light emitting diodes (LEDs) and liquid crystal indicators (LCD).

What is an earth fault indicator?

Units that detect a current imbalance due to an earth fault will trip and indicate by either bright LED or a mechanical flag. The EFI helps to quickly identify in which section of the network an earth fault is located, once the network has been tripped by the upstream protection.

What are indicators and conductors?

Conductivity, in general, is the capacity to transmit something, such as electricity or heat. indicator : thing that indicates the state or level of something.

What is fault why fault occurs?

An open-circuit fault occurs if a circuit is interrupted by a failure of a current-carrying wire (phase or neutral) or a blown fuse or circuit breaker. In three-phase systems, a fault may involve one or more phases and ground, or may occur only between phases.

Which are the electrical fault?

In the electrical power system, the faults are mainly two types like open circuit faults and short circuit faults. And further, these types of faults can be classified into symmetrical and unsymmetrical. Let us discuss these types of faults in detail. These faults are classified into two types.

What is the principle of dial indicator?

The working principle of the Dial Indicators is that the movement of the spindle multiplied with the reading of the main scale due to the indication of the needle. In addition to this, at the main scale rotation of pinions and gears is indicated.

What are the two basic types of indicator movements?

In the most general sense, there are two types of indicators commonly used in shop environments: test indicators and drop indicators.
