The GE Hydran H200i Calibrator BR (originally developed under the Syprotec Instruments brand) is a high-precision calibration control device engineered for the Hydran 103B and H200i series of dissolved gas and transformer incipient fault detectors. This portable instrument is a core component within electrical utility maintenance frameworks, providing field technicians with a reliable method to calibrate, test, and audit online gas monitors. By simulating specific fault-gas thresholds, it ensures that transformer tracking sensors accurately record composite ppm levels of hydrogen (H_2), carbon monoxide (CO), acetylene (C_2H_2), and ethylene (C_2H_4) to prevent catastrophic transformer breakdowns.

Application Fields
The H200i Calibrator BR is highly targeted toward utility and power grid maintenance:
- Substation Transformer Audits: Performing routine scheduled calibration intervals on online DGA (Dissolved Gas Analysis) monitors mounted to high-voltage step-up transformers.
- Asset Lifecycle Management: Validating that older gas-sensing cells have not experienced sensor drift due to continuous exposure to hot insulating oil.
- Commissioning Inspections: Bench-testing newly rebuilt Hydran sensors before mounting them onto active tank valve points.
- Industrial Power Generation: Ensuring stable, trip-free operation of large generator step-up (GSU) transformers in nuclear, thermal, and hydro plants.
Product Usage Instructions
- Preparation and ESD Safety: Place the calibrator kit on a flat, stable surface within the substation yard. Ensure you are clear of high-voltage induction paths and wear proper safety gear (FR clothing and safety glasses).
- Hose and Regulator Coupling: Attach the high-purity calibration gas mixture bottle to the regulator lines. Securely run the silicon pressure hose lines from the calibrator outlet directly to the verification port of the target Hydran 103B/H200i monitor.
- Flow Calibration Verification: Adjust the fine needle valves to control the injection velocity. The standard allowable flow specification across typical GE gas monitors ranges from 260 to 410 ml/min under a stable delivery pressure envelope.
- Threshold Alignment: Inject the sample gas into the sensor housing and monitor the telemetry readout on the Hydran display. Utilize the calibrator controls to adjust the internal baseline until the ppm readout matches the certified concentration of the tracking cylinder.
- Purging and Disconnection: Once the calibration point is locked into the monitor’s software memory, close the cylinder valve entirely. Bleed off residual line pressure through the calibrator bleed valve before unscrewing the quick-disconnect interface blocks to prevent air ingress into the transformer valve assembly.
Q&A – Frequently Asked Questions
Q: Why does my documentation refer to Syprotec instead of General Electric?
A: Syprotec Instruments was the original engineering firm that designed the Hydran family of transformer fault detectors. GE acquired Syprotec to absorb the technology into its Grid Solutions and Digital Energy portfolios. Consequently, older calibrator kits carry the Syprotec name, while newer iterations are labeled under GE.
Q: How often does the H200i Calibrator kit itself require certification?
A: To preserve regulatory grid compliance and maintain sub-ppm accuracy, the physical calibrator hardware should be sent to an ISO/IEC 17025 accredited laboratory every 12 months for NISTtraceable recertification.
Q: Can this calibrator be used for multi-gas monitoring systems like the Hydran M2-X?
A: Yes, it is functionally compatible with the core gas tracking channel of the M2 series. However, for full-scale DGA devices that calculate individual moisture-in-oil metrics or separate gas bands, advanced multi-stage gas regulation manifolds may be required.
Q: Where can I submit an application for current instrument pricing, calibration services, or a quote?
A: For official lead-time estimates, certified replacement seals, and comprehensive warranty coverage options for new or certified refurbished units, please visit our GE Hydran H200i Calibrator Procurement Portal.
