Description
Capacitive voltage transformers NDKM-330 UHL1 are single-phase electromagnetic scale measuring converters. The principle of operation is based on large-scale conversion of high voltage in a given number of times by means of capacitive voltage divider and electromagnetic transformer. They are intended for transmission of measuring information signal to measuring instruments, protection, automation, signalling and control devices in AC power networks of industrial frequency of voltage class 330 kV with blind or effectively earthed neutral. The transformer design is hermetically sealed and consists of an active part placed in a hermetically sealed tank (EMU) and a capacitive voltage divider. They require minimal maintenance costs. No chief engineer is required during commissioning. It is sufficient to check the oil level during operation. Oil sampling is not compulsory and is at the discretion of the operating personnel.
