HANDHELD CT BURDEN TESTER: MODEL 704

This small battery powered tester is ideal for carrying out
quick burden checks in CT metering and protection circuits.

The clipon CT (pictured) is connected to the CT secondary wiring and the crocodile clips attached to the CT terminals.
The instrument calculates the burden as the ratio of voltage over current.

The burden measurement accuracy is typically 1% at 5A and 5V, and decreases to 5% at 0.01A and 0.01V.
