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 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.
What is the Name of the transformer in which the output AC voltage is less than the input AC voltage?
It is a step-down transformer.
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.
