1 Executive Summary
Background:

Navitus Controls & Equipment (P) Ltd (NCEPL) received a contract from IOCL Gujarat refinery for online partial
discharge monitoring of 33kV cables, HT transformer & motor termination box, Transformer main tank, 33kV,
11kV, 6.6kV switchgears. The contract has defined the test procedures and also mentioned the type of sensors
that are to be used for testing each of the target assets. However, NCEPL not only complied with the stated
procedures and the type of sensors specified against each type of the asset but also deployed additional
sensors to achieve better sensitivity for the tests performed. The following table describes the sensors specified
in the contract and the additional tests performed by NCEPL team for achieving higher sensitivity and data
comparison among various sensors for better accuracy.

Type of asset Tests performed as per SOW in the Additional tests Remarks
tender performed by NCEPL
Cable EMI based PD test in HF range, TeV/ Contact type acoustic
terminations & UHF at the cable terminations and testing at the
cable accessible joints. 72 hrs.Continuous terminations and
monitoring in case of high PD activity accessible joints for data
with rising trend. corroboration

Test summary& criticality analysis:

The project envisages repeated testing of the target assets based on their criticality. In the 7th Phase of the
project NCEPL tested the following assets.

 33kV cables- 214

NCEPL team has followed a proven testing methodology and has collected the On Line PD data of these target
assets for detail analysis. Depending on the outcome of the analysis, NCEPL team has classified the assets
into different categories based on their criticalities. NCEPL team has also provided specific recommendations
against each type of criticality. Recommendations provided are based upon NCEPL experience against various
types of discharges.

The progression of PD is a complex activity and depends on many factors making it almost impossible to
predict the time to failure for these PD pulses. It is through repeated testing IOCL has to determine the trend
analysis and a fast-increasing trend is what is most critical and requires immediate intervention. Hence it is
helpful to have the failure history of the target assets before any On Line PD Monitoring is performed on an
asset.

The assets with criticality ORANGE should be immediately inspected. The detailed recommendations were
provided in the detailed report later in the document. However, the criticality marked in YELLOW shall also be
inspected as per the recommendations. Failure history shall be shared for more accurate criticality assignment.

Conclusion:

NCEPL team has completed the 5th Phase of the testing and shall undertake the next phase in close
coordination with the IOCL team. Meanwhile, NCEPL urges IOCL to open the assets marked critical and look
for physical marks/ traces of PD in these assets. If found these deteriorations need to be fixed and the assets
can be re-tested after that.

2 Background & Objective

Navitus Controls & Equipment (P) Ltd (NCEPL) received an order from M/S India Oil Corporation
Limited, Gujarat refinery for the online partial discharge testing of the following:
1. Condition assessment of HT 11/33 kV switchgears- 1200 EA
2. Localization of PD activity in 11/33kV switchgears- 100 EA
3. Online PD testing of 6.6kV switchgears- 1848 EA
4. Localization of PD activity in 6.6 kV switchgears- 50 EA
5. Online PD testing of 33 kV cables- 880 EA
6. Cables, cable joints & end termination- 360 EA
7. Diagnostic testing of HT cables- 20 EA
8. 72 hrs continuous monitoring of PD in critical cables- 10 EA
9. Online PD testing of transformer terminal box & motor terminal box- 2240 EA
10. PD monitoring of transformer main tank through UHF drain valve sensors- 10 EA
11. Diagnostic testing of transformers- 8 EA
12. Condition monitoring of HT/ LT motors- 5 EA
13. Diagnostic testing of VCBs of HT panels- 10 EA
Testing modalities were defined by IOCL in the tender as follows:
1. For 11 & 33kV switchgears, PD monitoring shall be done in UHF range using UHF sensors.
2. For PD localization, HFCT/ UHF/ Ultrasonic/ offline PD test shall be carried out for locating the PD in
the switchgear (33 kV & 11kV)
3. For 6.6 kV switchgears airborne acoustic & TeV technology shall be used for PD identification &
localization.
4. For 33kV cables, cable terminations and the whole cable shall be tested through EMI/ HFCT based
sensors & TeV or UHF sensors at the terminals.
5. Critical cables shall be subjected to 72 hrs of continuous monitoring.
6. 6.6 kV transformer terminal box & motor terminal box shall be monitored using air-borne acoustic &
TeV. PD testing has also been done using EMI based sensors for HT motors.
7. PD identification inside the transformer tank shall be done through UHF drain valve sensors.
8. Location of PD in transformers shall be done through four acoustic & one HFCT sensor technology.
NCEPL engineers used multiple On Line PD Testing equipment to ascertain the test results as per the
technology requirement guided in the work order/ tender. The equipment that were used are:-

 PD-30 (TeV & Ultrasound measurement device)

 PD 74 (Acoustic, UHF Rod & Guide Antenna, TEV, HFCT)
 Pry-CAM Portable (EMI Based Antenna/Sensor)

 PD-13 (Acoustic & HFCT based device for location analysis in switchgears

 PD-71 (UHF PD monitoring & localizing system)

 UHF drain valve sensors

 Failure history of each asset tested (if any) shall be provided by IOCL for more accurate
prediction. The failure history (or previous PD test readings) of the assets shall be mandatory
for providing recommendations after the first round of test.
 To conclude NCEPL would like to thank IOCL for giving this opportunity to undertake the On

TEST-1

The TeV test has been carried out for the cable of the feeder. The result is as follows:

Cable 1 2
TeV (dBmV) 6 8

TEST-2

Test-2 has not been conducted through HFCT based device as the common earth sheaths of the
three cables were not accessible.

TEST-3

Test-3 has been conducted through EMI based device in advanced mode, of all the cables. The
results obtained are asfollows:
