Description
ETCR9000 Series High/Low Voltage Clamp Meter offers a breakthrough in the traditional design, specifically engineered for accurate measurement of high voltage AC current. Utilizing advanced CT and digital integration technologies, this instrument comprises a specialized clamp current meter and an insulated high-voltage rod, ensuring precision and safety during measurement.
Features
- Innovative Design: The ETCR9000 features an integrated clamp and guide area, providing exceptional accuracy, reliability, and stability, even during year-round uninterrupted testing.
- Versatile Measurement Capabilities: When used with the insulation rod, the ETCR9000 can measure high voltage currents up to 110kV. Without the insulation rod, it serves as a high-accuracy low voltage clamp current meter.
- Multiple Functions: The meter offers peak hold, data hold, and data storage functionalities, making it highly suitable for online current monitoring. The unique clamp design allows easy operation by pushing or pulling the insulation rod to clamp or withdraw the tested wire.
Applications
- Widely used in substations, power plants, industrial and mining enterprises, and electrical maintenance departments for current detection and field operations.
- The ETCR9000 can also replace traditional H/L voltage transformation ratio testers by measuring the high and low voltage currents of primary and secondary circuits, respectively, and calculating the transformation ratio.
