What else can I help you with?
What is standard earthing of electrical equipment?
i have a question? in the earthing system should we connect the negative pole of supply to the earth for example a +24 power supply?
Why telecom power supply has 48V dc power supply?
because the termination and relays in side the telecoms penal needs for DC supply to continues the protection equipment and relay and purpose of telecoms
What is meant by PEN conductor when referring to earthing of supply system?
Conductor combining the functions of both a protective earthing conductor and a neutral conductor
Difference between ac and dc bridge?
DC Bridge... We use DC supply, Detector is also a DC current detector and we use only resistive components no need for wegner's earthing device balancing time is comparatively less.. where as in AC bridges opposite of above. i.e. AC supply, AC current detector resisitive+ reactive componants need for wagner's earthing device and balancing time is high as we use AC supply..
Why you use 2core cable for Dc motorCan you use 3core?
Mostly for small dc motor, 2core are used. earthing can be achieved by grounding the chassis.
Can TV be run by DC supply?
no... run tv with dc supply
What is applications of earthing?
An earthing system can be defined as the electrical potential of the conductors relative to the EarthÍs conductive system. The choice of earthing method can influence the safety and electromagnetic compatibility of the power supply, and regulations can vary considerably among countries.
What is the effect of good earthing on power supply?
Good earthing ensures that should a short takes place in an electrical appliance, any charge is sent safely to earth.
Can you use a ac to dc power supply rated 12 V at 1.0 A for a device that needs 7.5 V at 1.4 A?
You can't. Buy the correct power supply.
Why transformer can not be used in dc supply?
The transformer cannot be used in the DC supply because it keeps on alternating its current, whereas the DC supply current should be constant.
Why DC supply is used in control circuit?
dc supply is used for control circuit because dc current is an independent source .
How many types of earthing methods are there?
There are at least six types of earthing system, identified as follows:TNTN-CTN-STN-C-STTITThe first letter indicates the type of earthing at the distribution transformer, with T (= 'terre') indicating that one or more points of the supply are directly or 'solidly' earthed (e.g. an earthed neutral), and I indicating that either there is no earth at all, or earthing is achieved via an impedance.The second letter indicates the earthing arrangement at the electrical installation, with N indicating that all conductive parts are connected to an earth terminal provided by the utility company, and T indicating that the conductive parts are connected directly to a buried earth electrode.The third letter indicates the arrangement for the earthed supply conductor, with C indicating that the supply's neutral and earthing conductors are combined, and Sindicating that the supply's neutral and earthing conductors are separate all the way from the transformer.The fourth letter, S, indicates that within the installation, the neutral and earth conductors are separate.(The TN-C-S system is also commonly known as 'protective multiple earthing'.)
