What is meaning of lv leads hv with 30 degree?
"LV leads HV with 30 degrees" typically refers to the phase relationship between low voltage (LV) and high voltage (HV) electrical systems. In this context, it indicates that the voltage of the LV system is leading the HV system by 30 degrees in terms of phase angle. This phase difference is important in power systems to ensure proper synchronization and efficient operation of electrical equipment. Overall, it highlights the timing difference between the two voltage levels in an electrical circuit.
What zone is the point along the shoreline between the lowest and the highest high tide line and the lowest low tide line?
The slack water area is the space that lies between high and low tides
The difference between water levels at low and high tide-?
Water level is how deep the water is. High and low tide is when the water is washed in and out.
The difference between low and high tide is referred to as?
tidal range
Is low voltage harmful to electronics?
No the low voltage is not harmful for all ever . if you applied low voltage than the output power of your device will low and you can also observe that the performance of your device will also reduce. it may also make the device inactive.
What is the main difference between HT and LT Lines?
It's the voltage: HT high voltage LT low voltage Tension = voltage (French?)
What is the difference between LVD and HVD?
Lvd: low voltage differential Hvd: High voltage " signalling techniques
What is the difference between low voltage release and low voltage protction?
After a power failure, a device with low voltage protection will not restart automatically after power is restored to normal. This normally means that the breaker must be reset. A device with low voltage release automatically starts when power is returned to normal.
Difference between linear IC and Digital IC?
In linear IC'S the output voltage is very according to input voltage In digital IC's the output voltage is either high or low
How much voltage in phase to phase?
First of all, the correct term is 'line to line', not'phase to phase'. The line to line voltage is called a line voltage, and its value depends on the electrical standards in your country, and the point in the electrical tranmission/distribution system where it is measured. In the UK, for example, its value could be between 400 kV (high-voltage transmission line) and 400 V (low-voltage distribution line).
What do line voltage thermostats have that low voltage thermostats don't?
Line voltage sometimes varies according to how much load there is from neighbours and other users. When the voltage is high, the water heats more quickly so that the thermostat cuts out sooner, so the amount of energy used ia about the same. <<>> It is the difference in construction of the two thermostats. A line thermostat uses a bi-metal sensor to open and close the line voltage. The room temperature fluctuation has to be greater between the stat turning on to off, as the differential setpoint can not be regulated as fine as a low voltage stat. A low voltage thermostat uses a mercury switch that is operated from a spring that senses the room temperature. Low voltage thermostats do not control the line voltage to the heater but use a remote contactor to open and close the voltage supply to the heater. There is a compensator in the low voltage stat that can be set for the contactor's coil current. This way the temperature generated by the coil of the remote contactor is nulled and the thermostat only reads the room temperature. The differential setpoint on a low voltage thermostat has a finer setting than that of a line thermostat, so a more accurate temperature is maintained.
What is the difference between switchgear and switch yard?
we use switchgear for low voltage while switchyard is use for highvoltage transmission and distribution . There is an other factor known as insulation because for low voltage we should low insulation and for high voltage we need higher insulation.Cost is another factor between both.

What is low voltage ic 723 regulator?
ic voltage regulator is good for line or load regulation
What does inductive load effect on High Voltage transmission line?
the inductive load which is generally use in high voltage transmission line known as transformer. the transformer transform the high voltage to low voltage.
What are the differences between high and low voltage in electrical systems?
High voltage and low voltage in electrical systems refer to the amount of electrical potential difference present. High voltage systems have a greater potential difference, typically above 1000 volts, and are used for long-distance power transmission and industrial applications. Low voltage systems have a lower potential difference, typically below 1000 volts, and are commonly used in residential and commercial buildings for lighting, appliances, and electronics. The main differences lie in the safety precautions, equipment requirements, and applications of each voltage level.
What are the difference between bus reactor and line reactor?
Bus reactors are the inductors that limit voltage transients between a couple sections of a bus or a couple separate buses. Line reactors are capacitor or user amperage stabilizers placed at points of usage or right before transformers.
How do you calculate current and voltage in an extra low voltage circuit?
There is no difference of magnitude to be considered the end product is the same.
