Multiphase circuit, it is the tension between the phases. Note - Standard rated voltage control circuits are set standards for embedded component elements. Manufactured by NKU should set limits the voltage required for the normal functioning of the main and auxiliary circuits. In any case, under the rated load of built elements, the voltage control circuits at their terminals must be within the limits specified in relevant standards. 4.1.2 Rated insulation voltage (circuit NKU) Rated insulation voltage (Uc) chain NKU is the stress which characterizes the design of GCC, and in accordance with which the dielectric properties of the test, check the clearances and creepage length. Maximum rated working voltage of any circuit NKU should not exceed the rated isolation voltage. It is assumed that the voltage of any circuit GCC should not be even temporarily exceed 110% of rated insulation voltage of this circuit. Note - For single-phase circuits with isolated neutral and earthed exposed conductive parts (IT) (see 30331.2/GOST GOST R 50571.2), isolation voltage should be at least equal to the voltage between the phases of the power source. 4.1.3 Impulse Withstand Voltage (Uimp) (chain NKU) Peak value of impulse voltage prescribed form and polarity, which circuit NKU able to withstand without damage at these test conditions, and under which establishes the value of clearances. Rated impulse withstand voltage circuit GCC must be equal to or greater than the specified value surge transients that appear in the system to which GCC is attached.
