Hello guys, welcome back to our blog. In this article, we will discuss the tools used in substations for testing the devices or equipment, or the types of testing carried out in substations.

If you have any electrical, electronics, and computer science doubts, then ask questions. You can also catch me on Instagram – CS Electrical & Electronics.

Tools Used In Substations For Testing

First of all, we try to understand which types of testing are necessary to maintain the substation’s reliable operation. Scroll down and you can be able to see the name of a type of testing.

Protection testing
Measurement equipment testing
Power transformer testing & monitoring
Instrument transformer testing
Circuit breaker/switchgear testing
Rotating machines testing & monitoring
Cable testing & monitoring
Transmission line testing
Insulation resistance testing
Earthing resistance testing

Now let’s discuss different equipment for purpose of testing in substations and their uses. And one more thing in the last I will show one multi-function testing device which is affordable to use nowadays.

01. Transformer Turn Ratio Testers

In electricity transformer Finished product manufacturing process, earlier than the new set up of the transformer in operation, in accordance to the countrywide ministry of preventive take a look at procedures, require the operation of transformer flip ratio or voltage ratio test, to test the correctness of the transformer flip ratio tap-changer of transformer whether or not inter flip brief circuit transformer whether or not can run parallel.

Latest tool names:

TRF-250A,
T-203,
ATRT-01/01B S3,
CVT-765

02. Current Transformer Testers

These testers are used to perform phase accuracy, winding resistance, composite errors, burden impedance, CT type, transient CT classed, and parameters. Also, analyze the effect of CT saturation.

Latest tool names:

EZCT-2000C
EZCT-2KA
CT Analyzer

03. Circuit Breaker Analyzers

Circuit breaker analyzers can be used to fully analyze the performance of circuit breakers. It is used to check whether the circuit breaker will operate in faulty conditions or not. Some tests are carried out on the circuit breakers like mechanical, thermal, dielectric, and short-circuit.

Latest tool names:

GDWG-III
CT-8000 S3
DigiTMR S2
MCCB-250

04. Micro-ohmmeters

Ohm-meters are generally used to measure earthing resistance. In addition, it is also used to define CB contact resistances, bushing contact joints, welding joints, and any low-resistance measuring application.

Latest tool names:

DMOM-600
Auto-ohm 200 S3
Auto-ohm 10
SGT-200

05. Relay Test Equipment

Relay test equipment is suitable for testing different types of relays. In terms of relay various types of testing are done like inspection of contacts, Automatic self-test of the relay, Screws checked for tightness, over current rating, etc.

Latest tool names:

RFD-200 S3
PCI-600

06. Insulation Resistance Tester

These testers are used to measure high resistance which is the resistance of insulations. The purpose of this kind of testes is to prevent equipment from hazards.

Latest tool names:

Megger
CDAX 605
DELTA4000
HPA100AC
HPA130DC

07. Multi-Functional Testing Device for Substation (All-in-one testing solution)

The versatile CPC-100 can be simply used to function many popular and superior diagnostic tests on a number of electrical assets, inclusive of power transformers, current and voltage transformers, circuit breakers and switchgear, rotating machines, grounding systems, as properly as cables, and transmission lines. It replaces a number of manpower and testing devices, decreasing the fees for transport and coaching as nicely as minimizing checking out time.

Merits of CPC-100:

Compact and lightweight
Portable HV source
Variable test frequencies
High level of safety
Flexible operation
Easy to data handling and reporting

These are the tools used in substations for testing the devices or equipment. I hope this article “tools used in substations for testing the devices or equipment” may help you all a lot. Thank you for reading.
