Measuring current transformers ATM (hereinafter referred to as transformers) are designed to transmit measurement information signals to measuring instruments, protection devices, automation, signaling and control in AC networks with a frequency of 50 or 60 Hz.
Measuring current transformers ATM are designed for outdoor installation.
The current transformers have a cast housing made of epoxy compound by injection molding.
The insulation material of the current transformers has excellent arc, ozone and UV protection characteristics, while having high mechanical strength. The creepage distance and discharge distance of ATM current transformers are designed for high levels of air pollution.
ADVANTAGES OF CAST INSULATION CURRENT TRANSFORMERS:
Current transformers of the ATM series were developed for operation at transformer substations, traction substations of railways, at hard-to-reach facilities where equipment maintenance is not required, at enterprises with high pollution of electrical equipment operation.
Transformers meet the requirements of IEC, ANSI, IEEE, GOST standards.
Measuring current transformers ATM are a good alternative to obsolete and obsolete measuring current transformers with oil insulation.
