Test And Measurement Instruments

Polarization coupons are a means of measuring the amount of polarization potential. Given that instant off potential is usually used to measure the potential of structures interface with electrolyte (soil, water, etc.) or the same polarizing potential, for the cathodic protection system consists of several transformer rectifiers but the synchronization capabilities of transformer rectifiers are not available, polarization coupons are used.

In order to monitor the cathodic protection systems of the structures under protection, accurate information such as Instant Off potential and other information is obtained using appropriate measuring equipment. One of these types of measuring equipment are data loggers capable of recording and storing electrical parameters, including cathodic protection potential.

Instant off potential is used to evaluate the potential of the structure and its compliance with the cathodic protection criterion in structures under protection, when cathodic protection of a structure is carried out by several transformer rectifiers, all transformer rectifiers shall be simultaneously switched off and switched off in order to measure the instant off potential. It is necessary to use Cynchronize Interrupter to achieve this.

One of the recommended tests for the insulation of kits is the radio frequency test and the RF Tester is commonly used to measure the insulation of kits used in flanges. It works by connecting two probe to the two flange sides (so that the probes are fully connected to the flange) and the percentage shown on the device is read.

A portable test power supply can be used to facilitate the current expansion test or temporary impressed current of the cathodic protection system (where transformer rectifiers are not fully installed or energized).
