The last resort of protection to avoid electric shock can be arranged on the equipment itself rather than on the power supply side of the circuit. What is this protection called? Correct Answer ground fault detection

Ground fault detection:

  • It is the process of connecting non-current-carrying metal parts (i.e. metallic enclosure) of the electrical equipment to earth (i.e. soil) in such a way that in case of insulation failure, the enclosure effectively remains at earth potential.
  • This type of fault occurs on the equipment side rather than the power supply side.

The methods commonly used for grounding are as follows:

1.) Solid grounding:​ When the neutral point of a 3-phase system is directly connected to the earth, it is called solid grounding.

2.) Resistance grounding: When the neutral point of a 3-phase system is connected to the earth through a resistor, it is called resistance grounding.

3.) Reactance grounding: When the neutral point of a 3-phase system is connected to the earth through a reactance, it is called resistance grounding.

Additional Information

Phase fault:

  •  A fault that involves one or more phases and ground, or may occur only between phases is known as a phase fault.
  • This type of fault occurs on the power supply side rather than the equipment side.

Below stated are some of the statements about the Alternating current. You need to identify which of the following is incorrect, 1. DC power is far more powerful than AC power. The efficiency and power to size characteristics of DC motors and apparatuses are increased. Lighting by DC (LED) is 75% more efficient than lighting from incandescence. 2. A comparatively high voltage alternating current may be generated and easily raised and dropped by the static equipment known as the transformer, which makes electrical energy transmission and distribution economical, 3. Initial costs and maintenance of the AC motor are less expensive since it has no switch and is less powerful than the DC motor for constant working speed, hence it is desired to create power as alternating current. 4. The great efficiency of transmission in ac makes electric power generation cost-effective, Produced in huge quantities in one station and distributed throughout a vast area.
To talk about emergency situations, Priya asked children's experiences when they faced any emergencies. Children narrated their experiences with fire, electric shock and road accidents. She asked questions, assessed their existing understandings and discussed safety aspects using resources such as road safety advertisements from newspapers and also used LPG and electric bill to discuss safety guidelines on fire and electric shock respectively. Which is the most appropriate approach that Priya employed?
In comparing the operation of the half-controlled 2-pulse circuit with that of the fully-controlled circuit, which of the following statements are evident? 1. Since half the thyristors are replaced by diodes, a half-controlled converter costs less than a fully-controlled converter. 2. Due to the freewheeling action with a half-controlled bridge-circuit power factor is improved in half-controlled converters. 3. The AC supply current is more distorted due to its zero periods with the half-controlled circuit, compared to a fully-controlled bridge circuit. Select the correct answer using the code given below :
When an electric current coil of a wattmeter is connected to the electric current path R and the voltage coil is connected between the electric current R path and the neutral side of the balanced three phase supply, it shows 10 kW. The line voltage along the phase sequence RYB is 400 V. The current drawn by the current path is 54 A. What is the new reading of the wattmeter if the voltage coil is connected between the lines B and the Y paths, even if the electric current coil is continuously present in the line R?

S1: This is the story of a tram that woke up at dead of night and went off on a trip all by itself to end in a disaster.
P: In the early morning of 19 January it suddenly started backing out of the depot on its own.
Q: Tramways sources explained that power supply to the overhead wires at the siding had been switched off for some repair work.
R: It went up a quarter mile away, crashed into state bus which caught fire went it smashed into an electric feeder box and a water tap.
S: There was presumably, some defect in the reversal handle of the tram and its main switch had not been put off.
S6: As a result, when the power supply was restored in the early morning the tram began to move.
