Опис
The ЦК 0220 phase-zero circuit parameters meter is designed for measuring the short-circuit current strength (hereinafter referred to as the short-circuit current strength), total electrical resistance, phase-zero circuit voltage in 220 V alternating current networks, with a frequency of 50 Nz, with a dead-grounded neutral.
The meter determines the active and reactive components of total electrical resistance, the phase shift angle between voltage and current as information parameters.
The meter is used to control the parameters of the phase-zero circuit at energy facilities.
The meter is manufactured in accordance with the requirements of the Technical Regulations of Low-Voltage Electrical Equipment (hereinafter referred to as the Technical Regulations), approved by the Resolution of the Cabinet of Ministers of Ukraine dated 16.12.2015 No. 1067, DSTU EN 61557-3:2014 Electrical safety of low-voltage distribution networks with a voltage of up to 1,000 V alternating current and 1500 V DC. Equipment for testing, measuring or monitoring safety devices. Part 3. Total resistance of the circuit, Technical regulations on electromagnetic compatibility of equipment, approved by the resolution of the Cabinet of Ministers of Ukraine dated 16.12.2015 No. 1077, DSTU EN 61326-1:2016 Electrical equipment for measurement, control and laboratory use. Requirements for electromagnetic compatibility. Part 1. General requirements and DSTU EN 61010-1.
