Measuring current transformers TFZM-35 and TFZM-110
Oil-filled current transformers designed for outdoor installation in open distribution devices for transmitting a signal of measuring information to measuring devices (Ammeter, voltmeter, meters), as well as to protection, automation, alarm and control devices in AC power networks with a frequency of 50-60 Hz.The main internal insulation of transformers is paper-oil. Link type windings. The main insulation is located on the primary and secondary windings. The number of secondary windings is from two to five. Transformers are characterized by high reliability in operation.
Measuring current transformers TFZM of our production are made from 35 to 110 kV.
· altitude 1000m above sea level;
- ambient temperature from -60 to +50 C;
- relative humidity of 80% at an ambient temperature of +27.
During operation, the secondary windings of the transformer must always be closed to the devices or short-circuited
