Installed isolation transformer for rectifiers causes overcurrent tripping; rectifier company claims impedance mismatch requires larger auto-transformer, but electrician doubts necessity.
Rectifier company says isolation transformer impedance is too high and lacks switching capability for rectifiers, causing overcurrent trips; electrician suspects rectifier company may be pushing unnecessary upgrade.

Workarounds Described
- Consulted six other electricians to validate rectifier company's claim
Implied Software Gaps
- Low-impedance transformer selection tool for rectifier applications that accounts for switching harmonics and overcurrent protection coordination
App Concept
RectifierMatch Pro
A transformer-application compatibility analyzer that models rectifier loads and suggests optimal transformer kVA, impedance, and type (isolation vs auto). Prevents costly mis-matches and downtime by simulating electrical behavior before installation.
Key Features
- Load simulation with rectifier harmonics
- Impedance matching calculator
- Transformer type recommendation (isolation vs auto)
- Integration with electrical design software (e.g., SKM, ETAP)
Target Users: Industrial electricians and electrical contractors working with rectifier systems in manufacturing, plating, and painting facilities.
Revenue Model: $99/month subscription or $499 per analysis report
