Current Transformer Sizing Chart - Web how to properly size current transformers? To determine kva you must have at least two pieces of information: In actual practice, the cts draw a current to keep the iron core excited and drop a voltage proportional to the current transformed because of the inherent resistance of its windings. Other rated currents such as 1a exist elsewhere. Web this guide is intended to help you select the right quantity and type of current transformers (cts) needed for an egauge installation. If you need a device that converts from different voltages so it can power another device, then a transformer will fulfill that role perfectly. It also determines the turns ratio and type of transformer. The va rating determines the maximum secondary impedance (burden) that can be driven at the stated accuracy. Whether you need assistance with choosing the right ct, or have a related inquiry, contact us at dent. Web current transformers are available in a variety of styles, sizes, and amperage ranges.
