Product Details：
Product Dimensions：
The ABB (formerly Petercem/Bailey) EM010-9317 is a high-performance, calibrated Closed Loop Hall Effect Voltage Sensor. It is specifically designed for the precise measurement of DC, AC, and pulsating voltages in demanding industrial and railway environments. Utilizing fully electronic technology, it provides galvanic isolation between the primary high-voltage circuit and the secondary low-voltage measurement circuit, ensuring both high accuracy and safety.
Nominal Primary Voltage (Vpn): 1500 V
Measuring Range: Up to $\pm2250$ V (Peak)
Secondary Output Current: 50 mA at the nominal primary voltage
Supply Voltage: $\pm12$ V to $\pm24$ V DC ($\pm10\%$)
Accuracy: $\le \pm1\%$ at Vpn (measured at $+25$°C)
Linearity: $\le \pm0.1\%$
Thermal Drift: $\le \pm5$ µA/°C within the operating temperature range
Response Delay Time: $\le 100$ µs
Dielectric Strength: 6 kV (50 Hz, 1 minute) between primary and secondary circuits
Operating Temperature: $-25$°C to $+70$°C
Storage Temperature: $-40$°C to $+85$°C
Weight: Approximately 0.550 kg to 0.650 kg depending on the specific housing version
Primary Connection: 2 x M5 studs marked +HT and -HT
Secondary Connection: 5 x M5 studs
High Precision and Linearity: The closed-loop technology ensures that the secondary current is an exact replica of the primary voltage, maintaining high accuracy even under varying load conditions.
Galvanic Isolation: Provides excellent electrical separation (up to 6 kV) between high-voltage inputs and low-voltage control systems, protecting sensitive electronics and personnel.
Compact and Robust Design: Features a self-extinguishing plastic case and insulating resin, making it resistant to mechanical vibrations, shocks, and harsh external industrial conditions.
Wide Frequency Range: Capable of accurately measuring DC as well as high-frequency AC signals, making it suitable for modern power conversion systems.
Integrated Input Resistor: As a "Calibrated" model, the EM010-9317 includes an internal input resistor (RE), allowing the voltage to be measured to be applied directly to the primary terminals without external components.
Polarity Sensitivity: Ensure correct polarity when connecting the primary high-voltage terminals (+HT and -HT) and the dual DC power supply. Reversed supply polarity is generally protected but should be avoided.
Thermal Management: While the sensor has low thermal drift, it should be installed in an area with adequate ventilation to prevent heat buildup from affecting long-term accuracy.
Enclosure Requirements: The sensor's protection rating is typically intended for use within an electrical cabinet or protected enclosure to prevent contamination from conductive dust or moisture.
Load Resistance: The measuring resistance (RM) connected to terminal M must stay within the manufacturer's specified range to ensure the sensor stays within its linear operating region.
Safety Protocol: High voltages up to 2250 V may be present at the primary terminals. Always de-energize the system before installation or maintenance.
Railway and Traction Systems: Monitoring catenary voltages and DC bus voltages in locomotives, trams, and subways.
Renewable Energy: Used in solar inverters and wind turbine converters for high-voltage DC bus monitoring.
Industrial Drives: Measuring input and output voltages for variable speed drives (VSD) and large motor controllers.
Power Quality and UPS: Monitoring high-voltage battery banks in Uninterruptible Power Supplies and active harmonic filter systems.
Energy Storage: Voltage monitoring for large-scale battery storage systems and supercapacitor banks.
