Electrical testing & commissioning · North Gujarat
On-site electrical testing, reported against the limit.
Transformers, HT breakers, relays, CT/PT, cables, earthing and solar plants — tested at your site with calibrated instruments. Every sheet shows the acceptance limit, the reading and a clear PASS or FAIL.
01
Pre-commissioning
Tests and test certificate for UGVCL / GETCO energisation of new substations, transformers and HT lines.
02
Periodic and AMC testing
Scheduled testing of transformers, breakers, relays and earthing for running installations.
03
Fault diagnosis
Targeted tests to find the cause after a trip, failure or abnormal reading.
04
Solar plant testing
String, insulation, polarity and inverter checks for rooftop and ground-mount plants.

How we work
From enquiry to energisation
-
1
Enquiry
Call, WhatsApp or send the form with the equipment list, voltage level and site location. We confirm the scope and a date.
-
2
Site visit and testing
Our team tests on site with calibrated instruments, following the standard format for each equipment type.
-
3
Signed report
PASS / FAIL against the stated acceptance limits, with the raw readings and instrument calibration certificates.
-
4
Test certificate
A test certificate you can submit for energisation of the installation.
Why Inventrik
Reports you can check, and one team to fix what fails
15 standard report formats
Each equipment type has its own format, with the acceptance limits printed on every sheet.
Calibration certificates attached
The calibration certificate of every instrument used goes with the report.
Raw readings shared
You get the readings taken on site along with the report, not only a summary.
Testing plus rectification
Inventrik is itself a solar EPC and electrical contractor, so the faults we find can be put right by the same team.
Typical sites we test
- Rooftop solar plants
- Ground-mount solar plants
- Industries
- Hospitals
- Cold storages
- Dairies
- Petrol pumps
- Builders
