Tips: Voltage transformers vs. transformers

1. Function

• Transformers: These devices are primarily used for changing the voltage level in an electrical circuit. They can step up (increase) or step down (decrease) voltage while maintaining the same frequency.
• Voltage Transformers: Also known as potential transformers (PTs), these devices are specifically designed to step down high voltage to a standardized, safe, and measurable level for monitoring, protection, and control purposes.

2. Voltage Ratio

• Transformers: Transformers can have a wide range of voltage ratios to suit different applications.
• Potential transformers: PTs typically have fixed voltage ratios designed for accurate voltage measurement, usually at a 1:1 ratio or other standardized values.

3. Frequency Handling

• Transformers: Transformers can operate over a broad range of frequencies.
• Voltage Transformers: VTs are typically designed for a specific frequency, such as 50 Hz or 60 Hz, and may not function optimally outside of that range.

4. Load Handling

• Transformers: Transformers are capable of handling various loads, from low to high power.
• Potential transformers: PTs are designed for low-power applications and may not handle heavy loads like power transformers.
