BITE 2和BITE 2P电池阻抗测试设备说明书
BITE ®2 and BITE 2PBattery Impedance Test EquipmentnDetermines condition of lead-acid and NiCd cells up to 7000 Ahn On-board Pass/Warning/Fail indications n Robust, repeatable instruments n On-line testingnChecks charger condition by measuring ac ripple currentBITE ® 2 and BITE 2PBattery Impedance Test EquipmentDESCRIPTIONThe BITE 2 and BITE 2P Battery Impedance Test Equipment determine the condition of lead-acid andnickel-cadmium cells up to 7000 Ah. An advanced feature set has been developed that includes Pass/Warning/Fail calculations based on a user-entered baseline value, advanced printing functions and more. The case of the BITE 2P consists of both the transmitter and a carrying case for all of the standard accessories and some of the optional accessories, in an all-in-one unit. The BITE 2 and its accessories fit into a sturdy canvas case with a shoulder strap.The instruments work by applying a test signal across the battery string while on-line, then calculates impedance based on simultaneous measurements of current andresulting voltage drop of each cell/jar. They also measure dc voltage and interconnection (strap) resistance to help determine the overall condition of the entire battery string’s electrical path from terminal plate to terminal plate.In addition, the BITE 2 and BITE 2P measure ac ripple current which, if too high and over an extended period of time, can damage the battery by heating it. (An increase of battery temperature by 18ºF/10ºC will halve the life of lead-acid batteries.) Battery manufacturers generally recommend a limit of 5A of ac ripple current for every 100 Ah of battery capacity. The first measurement that the instruments take is ac ripple current which should be trended.The BITE 2 and BITE 2P receiver stores the readings in its internal memory. These measurements, along with other maintenance data such as ambient and pilot cell temperatures and ac ripple current, assist in determining the overall condition of battery systems. Meggerrecommends that impedance measurements with the BITE 2 or BITE 2P be made part of a battery maintenance program with readings taken and recorded semiannually for flooded batteries and quarterly for VRLA.Unlike load cycle testing that involves substantial downtime and repeated discharges, using the instruments require no battery discharge, nor do they stress the battery in any way compared to other techniques. With a test time of less than 15 seconds for each cell and intercell connector, one person can easily, quickly, and precisely measure internal cell impedance, dc terminal voltage and intercell connection resistance without taking the battery system off line and evaluate charger condition also.Naturally, everything you need to perform these tests is included with the basic instruments. There is a full line of optional accessories to enhance the capabilities of the BITE 2 and BITE 2P. Both have the ability to download to a PC for data interpretation and to ProActiv ™, Megger’s battery database management software. Additionally, the BITE 2P has a built-in printer to review the active test and also to leave a hard copy record at the site.ReceiverThe battery-operated receiver incorporates the potential leads, clamp-on current sensor, and data storagecapabilities. It stores more than 2000 sets of data (cell impedance, cell voltage and interconnecting strapresistance, date and time stamps) in up to 300 tests. It also allows for printing the active test for easy review and retest. Selective printing of any test and deleting oldest tests are now included features to maintain in memory the most critical tests.BITE 2PBITE 21981BITE ® 2 and BITE 2PBattery Impedance Test EquipmentAt any time while performing a test, the operator can review the current test results by using arrow keys and scrolling back through the active test screen. The operator can also print the active test using the BITE 2P transmitter printer. If needed, the operator can retest any of the cells and straps in the current test. Stored data can also bedownloaded via the RS-232 connector directly to a personal computer or the BITE 2P transmitter printer.One additional feature of the receiver is that if you are called away while in the middle of the test, simply shut down the instrument and it will remember where you left off in the test.The clamp-on current sensor is connected to the receiver during testing and clamped around a convenient intertier or intercell connection within the loop created by the transmitter’s current source leads and the battery string. If the intercell or intertier connection consists of more cables than the diameter of the clamp-on current sensor can encompass, the receiver has a split-strap function.There are optional RopeCTs TM available for large buss work. With the optional bar-code wand, additional information such as location ID, user ID, ambient and pilot celltemperatures can be recorded and stored. There is space on the printout to enter specific gravity readings.Data, measured and stored in the receiver can be exported to a PC. It can also be printed to the BITE 2P transmitter printer where it can be reviewed. Figure 1 shows a sample printout of a full battery analysis report.APPLICATIONSA battery’s internal impedance increases with decreasing capacity due to various conditions such as age, ambient temperature, discharge history, etc. See Figure 2. Both the BITE 2 and BITE 2P measure impedance values and dc voltage for lead-acid and nickel-cadmium cells up to 7000 Ah capacity.Impedance finds electrical path problems due to plate sulphation, post-seal corrosion, dry-out, and poor intracell and intercell connections. This information lets the operator determine maintenance needs such as:n Cell replacement criteria based on impedance trends.n Jumpering out a cell or two.n Clean and/or retorque intercell connectors.n Shorten the maintenance interval, etc.Typical installations that can be tested using the BITE 2 and BITE 2P include:n Electrical power generation plants.n Substations: utility, railroad, industrialn Telecommunications facilities: CO, Wireline, Wireless,MTSOn UPS systemsn Railroad: Signals and Communications, substation n Aircraft power supplies n Marine, militaryFEATURES AND BENEFITSn On-line testing requiring no downtime.n Enhanced printing and memory functions.n Calculates impedance automatically and stores resultsfor on-site review.n Requires no battery discharge.n Receiver has an RS-232 connector for downloading storeddata to a personal computer.n Reduced test time: less than 15 seconds for each cell.n Measures impedance and dc voltage values for all lead-acidand nickel-cadmium cells up to 7000 Ah.n Stores more than 2000 sets of readings in up to300 tests.n Checks charger condition by measuring ac ripple current.TransmitterThe transmitter provides the capacitively coupled ac test signal to avoid transients on the dc buss and applies it to the cells under test via the source leads. Both the BITE 2 and BITE 2P transmitters have an LCD and built-in receiver charger, while the BITE 2P transmitter features a built-in printer.Figure 1. Sample battery analysis reportBITE ® 2 and BITE 2PBattery Impedance Test EquipmentTest ProcedureThe BITE 2 and BITE 2P work by applying a capacitively coupled ac test signal across the battery string while on-line. The receiver and potential probe are placed at the cell terminals to measure the signal and resulting voltage drop for each cell/jar. During each measurement, impedance is calculated following Ohm’s Law, displayed on the LCD and stored. The instruments also measure, display and record dc voltage and interconnection (strap) resistance to help determine the overall condition of the entire battery string’s electrical path from terminal plate to terminal plate. The also measure ac ripple current, a charger parameter.The BITE 2 and BITE 2P receiver stores the readings in its internal memory. These measurements, along with other maintenance data such as ambient and pilot cell temperatures and ac ripple current, assist in determining the overall condition of battery systems. Figure 3 shows a typical test setup.Interpretation of ReadingsData produced by the BITE 2 and BITE 2P can beinterpreted in several modes: instantaneous, short-term and long-term time frames. An impedance distribution plot, as shown in Figure 4, assists in the analysis.Instantaneous InterpretationThe operator can enter a baseline value from either the impedance measurements obtained at commissioning or from the Megger website. The percent changes from baseline for warning and fail levels are entered, but 20 percent and 40 percent are the default settings. The LCD on the receiver will display the status of the cell for a few seconds before proceeding to the next cell. The status of each cell/jar will be printed on the Battery Analysis Report. Short-Term InterpretationImpedance readings for individual cells can be used in the short term to compare with the average impedance readings for the entire battery string. Individual cell values with deviations of more than ±15% for flooded lead-acid, ±35% for VRLA, and 50% for NiCd cells from the battery string average typically indicate a problem with that cell. Megger recommends additional investigation of such cells including a verification of intercell connections and a single cell load-cycle test.Long-Term InterpretationImpedance readings for the entire battery can be used in the long term to determine replacement criteria. Battery cell impedance values should be recorded and compared to previous readings to determine the position of the cell on the curve of impedance versus cell life as shown in Figure 2. Based on experience, a variation of ±20% from baseline for flooded lead-acid, ±40% for VRLA and 50% for NiCd cells indicate significant change in the electrical path to warrant serious evaluation of the condition of the battery system. Megger maintains a database of impedance values by some manufacturers and battery size/type. For comparison purposes, this information is available upon request.Figure 4.
