1- Transformer manual voltage regulation SOP.:

Transformer is a high voltage static device where the high voltage is increased and decreased and distributed for power utilization. If the voltage is low as per requirement then we will have to increased voltage through manually operated voltage regulation mechanism in OLTC of transformer. These voltage regulation process will be followed Under standard operating procedure which was written as step by step process with safety instruction so that any operation mistakes could be remove.
First of all we will have to take safety precautions then we can regulate the voltage as increased or decreased. Details of SOP given below mentioned.

2- Format of voltage regulation SOP:

3- Transformer voltage regulation procedure:

1- Object:

Transformer manual voltage regulation SOP- standard operating procedure.

2- Responsibility:

Technicians, technical supervisors, electrical engineers.

3- Safety instruction:

Before starting we must follow safety instruction.

• Use HT gloves for using this process.
• Use safety shoes.
• Use insulated tools.

4- Voltage regulation through transformer OLTC:

• Open the OLTC cover.
• Connect the handle into tap mechanism.
• Move the forward handle for voltage increasing.
• Move the backward handle for voltage decreasing.
• Check the required voltage on display.
• If the voltage is as required then stop the function.
• If the voltage is not as required then again start the procedure.

5- Voltage regulation through RTCC panel or motor:

• Select the selector Switch in manual mode.
• Press the up push button for voltage increasing.
• Press the down push button for voltage decreasing.
• Check the required voltage on display.
• If the voltage is as required then stop the pressing push button function.
• If the voltage is not as required then again start the pressing push button function.
