停電電纜相位識別器

Merytronic PI-3 停電電纜相位識別器是一款堅固耐用、操作簡便且具備先進數位技術的工具。它可協助使用者在變電站、電纜溝、人孔、配電盤、架空線與地下電纜的轉換處等場所，從多條導體中輕鬆識別出已停電的電纜及其各相相位。

發射器配備三個感應式夾鉗及三個鱷魚夾，因此無須變更發射器的連接方式，即可偵測同一饋線的各個相位。此外，本設備亦可用於識別切割前的停電電纜，以及已切斷的電纜，以便正確連接切斷處兩側的對應相位。

只需一台設備，即可識別中壓與低壓的各種類型電纜，且識別前無須進行校準。

主要特點

• 識別任何已停電的電纜
• 適用於單相及多相電纜
• 訊號注入方式：
  • 直接連接
  • 使用感應式夾鉗進行感應注入
• 最大電纜長度：超過 50 km (*)
• 發射器配備可充電電池；使用感應式夾鉗連續注入訊號時，運作時間超過 12 小時

使用前無須校準（出廠時已完成校準）。

(*) 採直接連接方式時，最大電纜長度的數值係以截面積為 50 mm² 的電纜測定。

De-energized 3-Phase Identifier

PI-3 de-energized phase identifier is a robust, user friendly and advanced digital tool. It helps users to easily identify any de-energized electric cable and its phases, among multiple conductors, in substations, trenches, manholes, panels, aerial/underground conversions, etc.

The transmitter includes three inductive clamps and three crocodiles. Therefore, it can detect each one of the phases of a feeder without changing the transmitter connection. It also helps to identify both de-energized cables prior to be cut and open cables (once they have already been cut) to join the phases of both sides correctly.

With a single device, any types of cables can be identified in both Medium and Low Voltage and it does not require calibration prior to identification

Main features

• Identify any De-energized cable
• Single-phase and multi-phase cables
• Signal injection:
  • Direct connection
  • Induced with induction clamp
• Max. cable length > 50 km (*)
• Rechargeable battery in transmitter. Operation time > 12h (continuous injection with inductive clamps).

It doesn’t require calibration before using it (calibrated at factory)

(*) Direct connection, value determined on cable of 50 mm²
