Substation Panel Wiring and Wiring Checks
During the commissioning of modern electrical power systems, like substation or industry environments, there are literally hundreds of connections that have to be verified. Next to the instrument transformer wiring, there are also logic signals, trip and control signals to breakers, different auxiliary signals and supply from the station battery and grid power.
Wiring problems, like the wrong polarity of a voltage or current transformer path, are one of the most common errors in electrical power systems.
Having the right equipment and the right procedures can substantially speed up those tests while improving personal safety at the same time.

COMPANO 100 + CPOL3
Our mobile, battery-powered test set COMPANO 100 is the ideal solution for all kinds of wiring checks, where AC and DC voltages and currents are required. With a DC-free sawtooth signal, which you can use in combination with the hand-held CPOL3 polarity checker, the wiring of instrument transformers can be checked without the risk of magnetizing them.
The COMPANO 100 Advanced Package includes all accessories required for this application as well as the software licenses.
Optimized for the field technician
Mains-independent operation
As a battery-powered test set, you can use COMPANO 100 even before a new substation is energized. Mains power is often installed in parallel with wiring checks and therefore not fully available, with COMPANO 100 there is no need for a portable generator.
Lightweight, portable test set
Due to its low weight of less than 10 kg/22 lbs, you can easily move COMPANO 100 from one test location to another. This saves you a lot of time, especially during wiring checks, and it increases your safety by avoiding tripping hazards due to long extension leads.
Electronically controlled sources
COMPANO 100 uses electronically controlled current and voltage sources. With these high accuracy signals you can check the wiring and the correct measurement of protection relays, meters, short-circuit indicators or modern SCADA systems at the same time.
High power output
With up to 110 A AC, COMPANO 100 lets you perform wiring checks with primary injection on current transformers. Adding the optional voltage booster VBO4 even allows you to use primary injection on voltage transformers or sensors requiring higher voltages of up to 750 V AC.
Handheld polarity and wiring checker
CPOL3 allows you to easily perform measurements without a cable connection back to the test set. Just hold it in your hand, place it on an electric cabinet with its removable magnetic backside or use it like a pen-style meter, with the included measurement tip.
Polarity checks with current clamp
You can use CPOL3 together with a current clamp to conveniently measure the polarity of the test current flowing through the wire at any location along the wire.
Perform multiple test steps with a single tool
CPOL3 combines the functions of several devices in one. There is a true RMS voltage display that makes it possible to assess the burden. AC or DC detection, which helps to detect additional wiring faults. The ""oscilloscope"" mode to graphically display the waveform, and a ""LoZ"" with low input impedance to suppress coupled signals.
CPX 200 + CPOL3
The CPX 200 multifunctional test system enables wiring checks for current and voltage transformers using both primary and secondary injection.
When used with CPOL3, it safely injects a low-current, DC-free sawtooth voltage signal without magnetizing the transformer cores. This enables precise wiring verification at every connection point, from the instrument transformer terminals to the burden.
CMC 310 + CPOL3
Our CMC devices focus on protection testing, but all them can also be used for wiring checks. Both operating options, CMControl as well as Test Universe, support the output of voltages, currents, and the CPOL polarity check signal needed for this application. The CPOL2 handheld polarity checker is required for testing CT and VT paths.
