Overview

The voltage drop timer JSY-2B JSY2B adopts advanced AC sampling and programmable logic device technology, and is produced using surface mount technology. It meets the requirements of the power industry standard "Technical Conditions for Voltage Loss Timer (DL/T566)" and has good electromagnetic compatibility design. Can accurately record the time of voltage loss in the PT secondary circuit of the energy metering device, and monitor the operating status of the PT secondary circuit of the energy metering device in real time. Give an alarm when the circuit loses voltage. To shorten the time of PT secondary circuit voltage loss, analyze and eliminate PT secondary circuit operation faults of electric energy metering devices, and provide a basis for compensating for erroneous power consumption, it can be used in conjunction with electric energy metering and billing systems to transmit relevant voltage loss fault information.

Product Details

1Accurately record the time of voltage loss in the electric energy metering circuit and calculate the corresponding amount of lost power: under the condition of load current, when the voltage loss in the electric energy metering voltage circuit (one phase, two phases or three phases) occurs, accurately accumulate the time of voltage loss, calculate the corresponding amount of lost power, indicate the phase of disconnection, issue a voltage loss alarm until the voltage is restored;

2Accurately record the state and time of voltage loss fault: When one phase, two phases, or three phases lose voltage, record the starting point (below the rated voltage) separately78%）End (greater than rated voltage)85%）Time, while recording the cumulative number and duration of voltage loss;

3Accurately record the no flow state and time: When there is no flow in one, two, or three phases, record the corresponding time, as well as the cumulative no flow time and number of times;

4Communication function: equipped withRS485Communication interface for on-site and remote communication; Equipped with an infrared communication interface for on-site parameter setting;

5Working power supply: with external connection220VACandPTTwo working power sources;

6Phase sequence error monitoring and alarm: display phase sequence and alarm for incorrect phase sequence;

7Voltage loss alarm method: Local and remote alarms can be achieved through panel indicator lights and relay output contacts;

8Estimate the amount of electricity that can be replenished when the voltage circuit loses voltage;

9Display three-phase voltage, current, and power;

10Display and record the voltage qualification rate;

11Used in conjunction with the electricity billing system: It can communicate with the main station and on-site collection devices of the electricity billing system to transmit information related to voltage loss faults.
