Measuring current transformers SMTSM (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 SMTSM 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 SMTSM current transformers are designed for high levels of air pollution.
ADVANTAGES OF CAST INSULATION CURRENT TRANSFORMERS:
Due to the fact that current transformers of the SMTSM series were developed for operation at high overloads, their application has widely proven itself in traction substations of railways, in hard-to-reach facilities where no equipment maintenance is required, in enterprises with high pollution and difficult operating conditions for electrical equipment.
Transformers meet the requirements of IEC, ANSI, IEEE, GOST standards
Measuring current transformers SMTSM are a good alternative to obsolete and obsolete measuring current transformers with oil insulation.
