The P3a is an advanced mini HV cable fault locator for LV, lighting and control cable & wire networks. The system allows proof testing (HV DC) and pinpointing (Surge) cable faults. In addition, the integrated inductive Arc Reflection Technology (ARTi) module enables the HV pre-location of high resistant faults in combination with an external TDR such as the INSCOPE140. Operation and parameter setting is controlled electronically for ease of use. A built-in discharge unit provides safety for the instrument, the operator and the device under test. Featuring a powerful surge unit that produces fast 4 sec. 450 Joule @ 3kV pulse cycles, the P3a is an efficient tool in reducing fault locating time.
