Product Description 3 Phase Voltammeter Vector Multimeter equals to CDM330C Color LCD AC clamp CT General Information:EP8410B The three-phase intelligent phase voltammeter is a multifunctional intelligent instrument designed for on-site testing. It consists of a host, current clamps (3), and test lines (4). The host uses a 3.5-inch true color LCD screen, graphical menu interface display, vector diagram instructions. The design of the small clamp head of the current clamp is easy to operate, and it is very suitable for places with dense wiring. The instrument can measure three-phase AC voltage, current, phase between voltages, phase between currents, phase between voltage and current, frequency, phase sequence, active power, reactive power, apparent power, without opening the circuit under test. Power factor, current vector sum, identify the transformer wiring group, inductive, capacitive circuit, test the secondary circuit and bus differential protection system, read out the phase relationship between the CTs of the differential protection groups, check the correct connection of the meter Otherwise, the maintenance of line equipment, etc., provides a safe, accurate and convenient smart instrument for the electricity inspectors. It is suitable for electric power, petrochemical industry, metallurgy, railway, meteorology, industrial and mining enterprises, scientific research institutions, metrology departments, etc. Especially suitable for electric energy billing system and relay protection system.Technical Specifications:1.
