How does the roof on wembley work?
The Wembley stadium has a movable roof and this depends on a hydraulic system to move the huge cover. The retractable roof allows the sunlight cover to be monitored and that allows the grass to grow.
How does a current transformer work?
A current transformer is used in high voltage circuits where it is not possible to measure current directly. A CT is a step up transformer with only one turn in primary. There will be as many cores based on the purposes like metering, protection etc. The secondary of a CT should never be kept open circuited bcoz very high flux will be developed in the secondary and hence it may be damaged.
Should your panic button be wired to the no or nc terminal. It doesn't say in the instructions.?
If the circuit of the panic button is monitored for a break in its circuit, the contacts will be in a N.C. configuration. There will need to be a relay in the circuit that is kept energized by the buttons closed contacts. When the relay drops out, its N.C. circuit contacts will activate the panic buttons load. If the panic button has no monitoring features then the contacts across the button will be wired in the N.O. configuration. When the button is pushed the circuit closes.
What is a device that increase or decreases voltage in a power line?
A transformer. A small example is the coil in a motorcar. A transformer, in a power line, only changes voltage in one direction under normal usage. At distribution voltages, about 8360 VAC, the voltage is monitored by a regulator. A regulator either increases or decreases the voltage automatically to insure the desired voltage is steady. This regulated voltage is then fed to Transformers to provide customers with a regulated voltage at the desired voltage.
What is difference between isolation transformer and earth protection relay?
An isolation transformer is a mutual transformer having a voltage ratio of 1:1, so that the secondary circuit is electrically isolated from the primary circuit, yet subject to the same voltage.An earth protection relay is a category of protective relay that responds to an earth fault monitored by a current transformer (CT). In the event of an earth fault being detected by the CT, the relay with activate the trip circuit to a circuit breaker which will then disconnect the fault.
Which two characteristic of network traffic are being monitored if a network technician configures the company firewall to operate as a packet filter Choose two?
*ports*protocols
Should media be monitored?
There are many media watchdog groups already, so yes, it is monitored. It should not be monitored by the government.
Why the resistance of an ammeter is bery low?
0. An ammeter is placed in series with the circuit in question; if its' internal resistance is high, it will change the current flow, thus making the measurement meaningless. For the same reason an ideal voltage meter will have infinite resistance.
Can text free with voice messages be monitored?
yes they can b monitored

What are some tips for the management of asbestos?
If one has asbestos in a building one should get a qualified technician to inspect for any damage to the asbestos. If there is no damage, it can be left but must be monitored. If damage is present, the area containing asbestos should repaired or the asbestos removed by a professional.
What is the use of measuring room temperature?
Objects that do not have a power source, will eventually take up the same temperature of the room. Measuring the room temperature, gives you a baseline energy level, so that energy levels of other objects can be monitored
