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.
