This is commonly a problem called "voltage drop". Simply, if you have any power supplying unit connected to an electrical load, it draws an amount of electrical current based on the load value. The voltage at the supply terminals is higher than on the load terminals, this is due to the resistance (impedance) of the connection wires (cables). The more the connection resistance (more resistance means less cross-sectional area), the less the load voltage (if source voltage and load current are kept constants). Another thing that affects the load voltage, is the load current itself. If the load current increases, the load voltage decreases (if source voltage and connection resistance are kept constants).
This means that any load current or connection resistance increase mean that the load voltage will decrease. This is exactly what happens in summer. In summer the ambient air temperature is high and hence all connection network elements (wires, cables, TL...) have higher resistance. Plus, most of the air conditioning units operate in summer (higher load current) which represent a bulk load to the network.
What else can I help you with?
What is Low Voltage Motors?
600v or less
What band is low voltage?
Less than or equal to 1KV comes under Low voltage.
An emitter follower has a voltage gain that is?
.7v less than unity for DC operation but unity for AC.
Can a capacitor charge to its maximum by applying any voltage to it?
A capacitor can charge to its' maximum OR the voltage applied to it, whichever is LESS.
In 3 phase voltage increases and current decreases why?
If the load current descrease, there is less voltage drop caused by the resistance of the wire, so the voltage is higher.
What to do when dogs eat less in summers?
they dont eat in summer at all
Is it true that Less watts will be spend when low voltage?
Yes. If you reduce the voltage to the same device, then it uses less power.
Is the mean rectified voltage now greater or less?
Less
Advantage of low voltage over mains voltage?
Less likelihood of electrocotion.
What is the effect of changing the voltage?
Less current.
What is Low Voltage Motors?
600v or less
What band is low voltage?
Less than or equal to 1KV comes under Low voltage.
What is th effect of Replacing a battery with one with fewer plates?
The battery voltage will be less. Batteries are arrangements of cells. The voltage of each cell is fixed depending on chemistry. Less plates means fewer cells, so the voltage produced by the battery in total will be less.
What is use of substaion near grid station?
A power substation is used to reduce the voltage from high voltage power lines to a voltage that is less dangerous that you can use in a house for example. It is less costly to transmit electrical energy over long distances using high voltage.
An emitter follower has a voltage gain that is?
.7v less than unity for DC operation but unity for AC.
If you operate an incandescent light bulb at less than its rated voltage?
Since an incandescent light bulb is an appliance that has a fixed electrical resistance, operating it at less than its rated voltage means that it will draw less than its rated current and will produce less light.
A high voltage combined with a low current will deliver less power than a moderate voltage combined with a moderate current.?
Correct. Power is determined by the product of voltage and current (P = V x I). A high voltage with low current has less overall power output compared to a moderate voltage with a moderate current due to the relationship between voltage, current, and power.
