The OLTC (On-Load Tap Changer) in a transformer is typically connected to the high voltage side.

• OLTC is connected to the high voltage winding of the transformer

• It allows for tap changing while the transformer is energized

• The low voltage side remains fixed while the high voltage side can be adjusted

Yes, OLTC is always connected in the HT voltage side.

• OLTC stands for On-Load Tap Changer.

• It is a device used in electrical power transformers to regulate the voltage level.

• OLTC is typically connected on the high voltage (HT) side of the transformer.

• It allows for tap changing while the transformer is energized and under load.

• By changing the tap position, the OLTC can adjust the transformer's output voltage.

• This helps to...read more

UV coil is a component used in HVAC systems to disinfect air by emitting ultraviolet light.

• UV coil is installed in the air handling unit of HVAC systems.

• It emits ultraviolet light to kill or deactivate microorganisms like bacteria, viruses, and mold spores.

• UV light damages the DNA and RNA of these microorganisms, preventing them from reproducing.

• UV coil helps improve indoor air quality by reducing the presence of harmf...read more

UV Coil provides protection against over voltage and under voltage.

• UV Coil is a device used in electrical systems to protect against voltage fluctuations.

• It monitors the voltage levels and activates when the voltage exceeds or falls below the specified limits.

• When the voltage exceeds the upper limit, the UV Coil disconnects the power supply to prevent damage to the equipment.

• Similarly, when the voltage falls below the ...read more
