Study Notes
MSENSE® DGA 2/3 Overview
- MSENSE® DGA 2/3 is an online oil analysis device designed for measuring gas concentrations, moisture, and oil temperature in mineral-based transformer insulating oil.
Measurement Capabilities
- DGA 2 measures hydrogen (H2) and moisture in oil.
- DGA 3 measures hydrogen (H2), carbon monoxide (CO), moisture in oil, and oil temperature.
- Measurement accuracy for H2 is ±10%, CO ±15%, humidity ±1.8% RH, and oil temperature ±1°C.
Detection Limits
- Lower detection limit for H2 is 15 ppm, CO is 25 ppm, humidity is 3% RH, and oil temperature is -20°C.
- Upper detection limit for H2 and CO is 2,000 ppm; humidity is 90% RH; oil temperature is +115°C.
Operating Conditions
- Suitable for indoor and outdoor use across all climate zones.
- Can operate at an altitude of up to 4,000 meters above sea level.
- Functional in ambient temperatures ranging from -40°C to +60°C and oil temperatures from -20°C to +115°C.
Mechanical Properties
- Connects via a ball valve with configurable flange options (DN50 or DN80).
- Two lengths for the measuring pipe: 285 mm (short) and 507 mm (long) to optimize measuring conditions.
- Oil extraction via a Luer lock socket; includes adapter set for safe oil extraction.
Device Specifications
- Optional VFD display for real-time readings and messages.
- Constructed from stainless steel and aluminum; parts in contact with oil are weather and UV resistant.
- IP66 rating indicates high resistance to dust and water ingress.
Dimensions and Weight
- Physical dimensions vary based on measuring pipe length: 435 mm (short) or 657 mm (long) x 218 mm x 264 mm.
- Weight is approximately 12 kg for the short pipe and 14 kg for the long pipe (excluding accessories).
Signal Protocols and Communication
- Supports DNP 3.0, Modbus TCP, and optional IEC 61850-8-1 MMS protocols.
- Requires additional protocol converter for certain signal protocols.
Accessories and Versions
- Optional power supply units and offshore-specific versions available for harsher environments.
- Standard installation location is directly on the transformer tank or within oil cooling pipes.
Protection and Safety Features
- Vacuum resistant to 5 Pa for 48 hours and pressure resistant up to 400 kPa.
- Includes safety chain for secure installation and removal.
