2.0 Introduction to the Universal Insulator Tester
2.1 General
The document describes the operation of Positron’s Universal Insulator Tester:
Model # 3782651U/50: Universal Insulator Tester, 50Hz
Model # 3782651U/60: Universal Insulator Tester, 60Hz
Refer to Figure 1 on page 6 for a detailed drawing of the unit.
With the Universal Insulator Tester field Probe mounted onto a user-supplied (non-conductive)
hot-stick, the user takes a reading by pressing the field Probe against the insulator, using the
Pressure Switch-mounted Insulator Edge Guide for proper positioning during testing.
Each time the Pressure Switch is triggered, a reading is taken. The electric field surrounding the
insulator is recorded. Defective insulators are easily identified using the resulting data graphs
that present the contour of the electric field surrounding the insulator. The field Probe contains
a microprocessor-based recording system.
After an insulator is scanned by the Tower Operator, the Ground Operator immediately
downloads the Probe’s data via a long range Bluetooth communication link to the Tablet/Laptop
for on-site analysis. Any conductive defect in an insulator will cause a change in the electric field
surrounding the insulator. This perturbation of the electric field indicates a faulty insulator.
The fault is detected, identified, and measured by the Probe, and the data is immediately
downloaded to a database installed on the Tablet/PC for analysis. The graph displaying the E-
Field of the insulator is clearly displayed on the Tablet/Laptop while in the field enabling
GO/NOGO decision-making on-the-spot.
The data is stored in ASCII format in order to be compatible with any text editor, including Excel
spreadsheet and Microsoft NOTEPAD, plus the ASCII data can be imported into existing
customer databases.

Verify the Date and Time settings of the Tablet/Laptop

It is important to disable the WIFI of the Tablet/Laptop to avoid long operating system
updates while performing a testing session.
