FAQs of current transformers and voltage transformers:

Q: How are these transformers used in industrial measurement and protection applications?

A: These current and voltage transformers are typically employed to step down high currents or voltages to manageable levels for metering, control, or protective relays in industrial electrical systems, ensuring operational safety and precise measurements.

Q: What accuracy classes are offered, and how do I choose the right one?

A: We provide accuracy classes of 0.2, 0.5, 1.0, and 3.0. The appropriate choice depends on the criticality of measurement accuracy in your application: for revenue metering or protection, lower numbers offer greater precision.

Q: When should I consider a split-core versus a ring or rectangle core?

A: Split-core models are ideal for retrofitting into existing installations without disconnecting conductors, while ring and rectangle cores are suited for new setups or when system downtime is permissible during installation.

Q: Where can these transformers be mounted in an industrial setup?

A: These devices are engineered for flexible installation options, including panel, surface, or DIN rail mounting, accommodating various switchgear cabinets and control panel layouts.

Q: What is the process for ensuring proper dielectric strength and flame retardance?

A: Every transformer is manufactured with insulation class B, F, or E, utilizing flame-retardant epoxy resin and tested to withstand 2.5 kV for one minute, ensuring durability and compliance with industry standards.

Q: What are the main benefits of using these CTs and VTs in industrial environments?

A: Key advantages include high efficiency (98%), robust electrical protection, minimal load loss (0.2%), and compliance with international standards, all of which contribute to system reliability, safety, and long service life.
