HV Resistance Box Calibration
Calibrationhouse provides expert calibration for HV resistance boxes, ensuring precise high-voltage resistance measurements for testing, calibration, and electrical applications.
What is an HV resistance box used for?
An HV (high voltage) resistance box, also known as a high voltage decade box, is a precision instrument that provides multiple resistor values for testing, calibration, and verification of electrical test equipment. These devices are particularly useful for calibrating insulation testers operating at high voltages.
How do HV resistance boxes differ from standard resistance boxes?
Unlike standard resistance boxes, HV resistance boxes are designed for high-voltage applications, typically up to 5kV (5000V), with some advanced models capable of handling 10kV (10,000V). They use precision resistors made from specialised materials to ensure low leakage and minimal measurement error when operating at high voltages.
Why is calibration of HV resistance boxes important?
HV resistance boxes serve as high-accuracy calibration tools for verifying less precise instruments. Since they are used to check and calibrate insulation testers, ensuring their own accuracy is essential to prevent measurement drift and incorrect resistance readings that could impact safety and performance.
Can Calibrationhouse perform on-site calibration for HV resistance boxes?
Yes, some on-site calibration services are available for HV resistance boxes across the UK. However, higher resistance standards are typically maintained at our Durham-based laboratory, where customers benefit from our rapid turnaround high-resistance decade box calibration service.
For customers in the United States, HV resistance box calibration is also available at our Tampa facility, ensuring compliance with BSI ISO9001-certified standards.
What is the maximum resistance value Calibrationhouse can calibrate?
Calibrationhouse offers UKAS-certified resistance box calibration on instruments up to 2GΩ (2 Gigaohms), using high-accuracy resistance standards to ensure precise and traceable measurements.
