B2 ELECTRONICS電纜測試儀HVA28-TD技術參數

B2 ELECTRONICS電纜測試儀HVA28-TD介紹

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 是真正小巧便攜的 VLF 測試儀，可確定中壓電纜的狀況。

與可擴展 TD 診斷單元的 HVA28 設備相比，HVA28TD 設備包括集成的 Tan Delta 診斷功能。

它們都執行 VLF 和 DC 測試，以及使用護套故障定位模式進行的護套測試。

性能：考慮到尺寸和重量與輸出負載的突出特點。

占空比：這些測試裝置的工作時間不受熱限制；它們可以連續運行。

安全第一：測試裝置有兩個獨立的接地裝置（電子和機械放電）和一個集成的 12 kV 瞬變保護系統（50 Hz），以保護操作員和設備。

現場使用：防水且非常堅固的外殼，防護等級為 IP67（帶封閉蓋），無需額外的運輸解決方案。

連接性：在現場，不需要外部 PC。以后可以通過 USB 或藍牙下載所有結果，以便通過軟件工具進行進一步調查和輕松報告。

服務和維護：干式變壓器沒有油或電弧觸點，使這些測試裝置幾乎免維護。

MWT：此外，HVA28TD 提供受監控的耐壓測試，這是符合 IEEE 400.2-2013 指南的耐壓測試和 Tan Delta 診斷的組合。

輸出電壓：29 kVpeak, 21 kVrms

輸出負載：0.5 μF @ 0.1 Hz @ 20 kVrms

重量：14 公斤/31 磅
