Detailed Description

Brief Introduction With fine arts and crafts and beautiful appearance, ST-9020 V3 Series Single Phase Energy Meter Testing Equipment is with optional accuracy of class 0.1 and class 0.2. The equipment adopts cabinet & rack structure and the meter positions are optional with 6, 8, 12, 24, 48 meter positions. Adopting series designs, the equipment is classified into different types, such as economic type, enhanced type, luxury type and high accuracy type etc., which are configured differently in accordance with the requirement of the customers. The equipment can be controlled via computer or special keyboard. Controlled via computer, special software are used for the realization of all functions; Controlled via special keyboard, the automatic test can be made according to national energy meter testing regulations. The equipment is suitable for the manufacture testing, performance examining, type test, quality identifying and some other tests to various energy meters used in electric power research institutes, metrology departments of electric power company, metrology institutes of technical supervision bureau and energy meter manufactures etc. Features and Functions •Various single phase inductive or electronic active energy meters automatic testing •Automatic testing of creeping, starting, basic error, standard error, 24h tail off etc in accordance with test regulation •Management software multilevel setting •Testing project can be made automatically in accordance with regulation and testing items and the project can be copied, amended, saved and deleted. Testing proceed automatically under program control, no need manual work. •Coefficient revising according to the system set by the user, error testing value automatic revising •Starting and creeping testing time automatic calculation in accordance with regulation, results automatic adjustment •Special error display for each meter position, which can be cleared separately, convenient for meter adjustment •Up to 120 KHz pulse output for each meter position, no frequency divider need for high frequency energy meter testing •If there is something wrong or sudden power off during the test, the current working state will be saved, convenient for comeback after trouble shooting •Various output parameters real time display, such as voltage and current amplitude value, power, frequency, phase etc •High-power electronic program control power source, with characteristics of low power consumption, high switch efficiency, powerful load ability, little influence to working environment temperature control etc •Adopting digital real-time feedback technology, output accuracy high, load adjustment rate low at loading point •Data saving and query function, testing results of 1000 meters can be saved •Voltage short circuit and current open circuit alarming •2～21st harmonic setting and output •Embed multi functional testing interface, beautiful and tidy, convenient for wiring checking •RS485 communication interface, multi energy meter communication protocol for energy meter communication testing Options •Fundamental wave wide range power energy meter for fundamental power, energy and harmonic energy error testing, wide current range without CT secondary error Specifications •Accuracy: class 0.1/0.2 •Voltage output Range: 220V （0.01% ~120% adjustable） Resolution of amplitude: 10%, 1%, 0.1%, 0.01% •Current output Range:0.1A～120A （range automatic setting） Resolution of amplitude: 10%, 1%, 0.1%, 0.01% •Max.
