B2 ELECTRONICS电缆测试仪HVA28-TD介绍
The HVA28 and HVA28TD are truly compact and portable VLF test sets which determine the condition of medium voltage cables.
HVA28TD device includes integrated Tan Delta diagnostics capabilities, in comparison to HVA28 device, which can be with the TD diagnostics unit extended.
They both perform VLF and DC testing, as well as sheath testing with sheath fault location mode.
Performance: Outstanding features considering size and weight vs. output load.
Duty cycle: Operating time of these test sets is not thermally limited; they may operate continuously.
Safety first: The test sets have two independent earthing devices (electronic and mechanical discharging) and an integrated 12 kV transient protection system (at 50 Hz) to protect both the operator and the device.
Field use: A watertight and very rugged case with protection class of IP67 (with closed lid) makes no need for additional transport solutions.
Connectivity: On site, no external PC is needed. All results can be later downloaded via USB or Bluetooth for further investigation and easy reporting via software tool.
Service and maintenance: With no oil or arcing contacts the dry-type transformer makes these test sets almost maintenance-free.
MWT: In addition, HVA28TD offers a Monitored Withstand Test, a combination of withstand testing and Tan Delta diagnostics in compliance with the guide IEEE 400.2-2013.
Output voltage:max. 29 kVpeak, 21 kVrms
Output load:0.5 μF @ 0.1 Hz @ 20 kVrms
Weight:14 kg / 31 lbs
HVA28 和 HVA28TD 是真正小巧便携的 VLF 测试仪，可确定中压电缆的状况。
与可扩展 TD 诊断单元的 HVA28 设备相比，HVA28TD 设备包括集成的 Tan Delta 诊断功能。
它们都执行 VLF 和 DC 测试，以及使用护套故障定位模式进行的护套测试。
性能：考虑到尺寸和重量与输出负载的突出特点。
占空比：这些测试装置的工作时间不受热限制；它们可以连续运行。
安全第一：测试装置有两个独立的接地装置（电子和机械放电）和一个集成的 12 kV 瞬变保护系统（50 Hz），以保护操作员和设备。
现场使用：防水且非常坚固的外壳，防护等级为 IP67（带封闭盖），无需额外的运输解决方案。
连接性：在现场，不需要外部 PC。以后可以通过 USB 或蓝牙下载所有结果，以便通过软件工具进行进一步调查和轻松报告。
服务和维护：干式变压器没有油或电弧触点，使这些测试装置几乎免维护。
MWT：此外，HVA28TD 提供受监控的耐压测试，这是符合 IEEE 400.2-2013 指南的耐压测试和 Tan Delta 诊断的组合。
输出电压：最大29 kVpeak, 21 kVrms
输出负载：0.5 μF @ 0.1 Hz @ 20 kVrms
重量：14 公斤/31 磅
