Data record `instr.meter-test-set.instrument-transformer-checks`

Verified 2026-10-27 Confidence: High

Field equipment also verifies instrument transformer ratio and polarity at the site and measures the burden on the current transformer secondary; a burden tester instead applies a known extra burden and watches how much the secondary current falls, a large fall pointing to a transformer that under-registers at the meter.
