The GE H200i is an electronic calibrator for the GE Hydran 201Ti transformer monitoring system. It is used during verification and calibration procedures for H201Ti electronics. GE documentation specifically lists the H200i as a recommended accessory, with approximately one calibrator recommended per site.
This is not a PLC or conventional process-control module. It is a specialized service and calibration instrument for transformer dissolved-gas monitoring equipment. The supplied eBay listing identifies the product as “GE H200i Calibrator BR” and lists the model as IP-QUADRATURE.

GE’s technical specification identifies the H200i specifically as the calibrator used during verification and calibration of H201Ti electronics.
⚡ Functional Description
The H200i provides technicians with a dedicated tool for checking and calibrating the H201Ti electronics used in the Hydran transformer monitoring system. The Hydran system monitors fault-gas conditions in transformer oil and provides information used for transformer condition assessment.
The H200i is therefore normally used as maintenance/calibration equipment, rather than remaining permanently installed as part of the monitoring system. GE’s documentation recommends one H200i calibrator per site.
🏭 Typical Applications
- Power transformer monitoring
- Transformer maintenance
- Hydran 201Ti calibration
- Transformer fault-gas monitoring systems
- Electrical utility substations
- Power-generation facilities
- Transformer commissioning
- Preventive maintenance
- Field service and troubleshooting
🔌 Calibration / Service Procedure
- Confirm the H200i model and condition.
- Identify the connected Hydran H201Ti equipment.
- Verify the calibrator’s required power source.
- Connect the H200i using the appropriate service interface.
- Follow the approved H201Ti calibration procedure.
- Apply the required calibration/reference signals.
- Compare the H201Ti response with the expected values.
- Adjust calibration parameters when required.
- Record calibration results.
- Disconnect the calibrator and return the H201Ti to normal monitoring operation.
🛠️ Maintenance Checklist
- Inspect enclosure and connectors
- Check battery/power condition
- Verify service cable/interface
- Confirm H201Ti compatibility
- Check calibration response
- Record before/after calibration values
- Verify H201Ti alarm operation
- Document calibration date and technician
- Store the H200i in a clean, dry environment
⚠️ Important Identification Note
The exact eBay listing you provided identifies the item as GE H200i Calibrator BR, with GE as the brand and IP-QUADRATURE shown as the model field.
GE’s own documentation provides the more useful technical identification: H200i Electronic Calibrator for H201Ti electronics.
Some third-party listings contain incorrect descriptions of the H200i as a transformer transmitter or flow-measurement device. Those descriptions should be avoided. The H200i itself is the calibration instrument, while the H201Ti is the transformer monitoring electronics.
