Class 0.5s, 0.2s or customised current transformers
Description
Current transformers are used to measure the current in an electrical circuit. The accuracy of this measurement depends on the transformer’s accuracy class. In an electrical installation, the current transformer is defined according to the rating of the circuit breaker.
The use of precision current transformers guarantees a low measurement error (± 0.5 or 0.2%) over a wide measurement range from 20 to 120% of the rated current. In comparison, a “standard” current transformer or a class 1 current transformer (± 1%) has an accuracy of 100 to 120% of the rated current.
These products are regularly used in installations requiring billing and are generally associated with MID energy meters. The areas of application can be varied: funders billing their tenants for energy, cost accounting for one service compared with others or energy management.
We sell current transformers from Frer brand, which designs, develops and manufactures a very wide range of precision transformers. This range starts at 5 A and extends up to 8000 A. We can also produce specific dimensions to suit your installation and space requirements. All products can be supplied with a test certificate (on request).
Ultra-precise measurements
A class 0.5s or 0.2s precision current transformer guarantees an accuracy of 20 to 120% of the rated current. In comparison, a class 1 current transformer (1% accuracy) is accurate to between 100 and 120% of rated current. A precision current transformer therefore enables you to guarantee the most accurate measurement over a wide range of use.
Developed and manufactured in Europe
We work with the Italian manufacturer Frer for more than 15 years. This collaboration guarantees us complete control of the manufacturing process. The products are carefully designed following a strict quality control procedure (test reports available on request).
Reliability and quality are our core concerns when we select our partners.
Tailor-made products
Based on your specifications, we can manufacture tailor-made products to meet all your specific requirements: special characteristics, reduced dimensions, etc.
Class 0.5s in opening version
Class 0.5s current transformers are also available in a split-core version. This range simplifies product installation and saves time for the contractor.
