CHVT

ACCURACY CLASSES: 0,1 (0,05 optional)

NATIONAL REGISTRY N: 32575-11

Purpose

The purpose of a high-voltage capacitive transducer is to measure high voltage applied to its high-voltage input by converting it into low voltage values with a standard-compliant scaling factor.

Field of application

  • A source of reference voltage in transformer test systems (suitable for testing instrument voltage transformers rated from 6 to 330 kV, 0.2 accuracy class or less accurate)
  • Voltage measurements on the high-voltage side

Documentation:

In response to the customer's specific needs, Mars-Energo specialists carried out preparatory checks and calibration of an additional electronic unit for the capacitive high-voltage transducer.

In 2023, Mars-Energo successfully supplied a set of equipment for the calibration of electronic low-power voltage transformers (LPIT) to the Republic of Korea. The set included two essential components:

1) Capacitive High-Voltage Transducer CHVT-220, accuracy class 0.05 at 220 kV/√3

2) Dual-channel Voltage Comparator MarsComp K-1000, accuracy class 0.01

The end user of this equipment is the research center of Hyundai company.

The calibration of the capacitive high-voltage transducer was conducted at Korea Research Institute of Standards and Science (KRISS).

The calibration report confirms that all metrological characteristics of the high-voltage transducer impeccably align with the customer's stringent technical requirements.
