Who we are

2

HVPD are experts in the growing industry

of partial discharge (PD) testing and

monitoring of in-service high voltage

cables and plant. We offer a complete

range of equipment that gives an early

warning of faults and deterioration in

medium and high voltage (MV and HV)

insulation, allowing plant owners to takeearly corrective action.

We provide bespoke solutions to our

growing customer base in the oil and gas,

renewables, shipping, transmission and

distribution, and power generation

industries.

Partial discharge is caused by disconti-

nuities and flaws in medium and high

voltage electrical insulation. PD activity will

eventually lead to complete insulation

failure which in turn can cause unplanned

outages and downtime. PD occurs due to

many factors including poor installation,

ageing, manufacturing defects, environ-

mental impact and third-party damage.

If costly unplanned outages are to be

avoided, it is vital to carry out regular PD

testing as part of a condition-based

management (CBM) regime. This enables

operators to take baseline PD readings in

order to evaluate insulation quality, to

locate PD activity sites and to target repairs.

CTs/VTs, and rotating machines in both

public utility and large private networks.

Our Wide Area Network PD Database

has been developed in conjuction with a

number of UK utilities including EDF

Energy/UKPN, Scottish Power and

Scottish and Southern Energy. It has

been designed to meet the require-

ments of the developing ‘Smart Grid’,

providing real-time, insulation conditionmonitoring systems for wide-area,

electricity transmission and distribution

networks.

We have supplied condition-based

assessment of MV and HV networks in the

power generation industry for over a decade,

providing our customers with diagnostic and

testing services, consultancy services,

training and PD monitoring systems.

Cables Switchgear

The formation of surface tracking and PD

related erosion can lead to in-service failures

thr ough flashover. HVPD’s technology can

be used to test Air-Insulated Switchgear

(AIS), Solid-Insulated Switchgear (SIS)

and Gas-Insulated Switchgear (GIS).

PD can occur in any MV or HV cable

operated at 3.3 kV or above. Our testing

can locate potential failure sites to within

0.5% of a cable’s overall length using the

technique of On-line Cable Mapping.

Case study

Case study

Switchgear PD monitoring for a

distribution utility customer

The HVPD Mini™ Monitor identified

rising PD levels in an 11 kV switchboard.

Transient Earth Voltage (TEV) sensors,

attached to the metal-clad switchgear,

identified surface discharge from two

panels. Intermittent PD activity between5 a.m. and 9 a.m. was caused by the

formation of condensation on insulation

surfaces as the dew point was reached

(this would have been missed if PD

spot-tests had been carried out during

normal working hours). The client was

able to correct this issue cost-effectively

by installing temperature-controlled

space heating into their switchboard.

On-line PD cable testing and mapping

for a light rail operator

A 33 kV XLPE cable system had been in

service for twelve months before faults

began to occur at cable joints. The HVPD

Longshot™ with PDMap© detected

high-magnitude cable PD activity on

multiple circuits.

Out of more than one hundred 33 kV

circuits tested, significant PD wasdetected within six, putting them in the

‘Red’ condition category: ‘Major concern,

locate PD and then repair or replace.’

The sources of PD were mapped and

located to specific joints which were then

replaced and retested to verify that the

repairs were successful.

Applications

On-line field applications Motors and Generators Transformers

On-line PD testing is now widely accepted

in the rotating HV machine industry as the

best way t o assess the stator winding

condition of in-service HV motors and

generators. Using the HVPD Longshot™

PD diagnostic system with its dedicatedPDGold© software it is possible to carry

out both on-line (in-service) and off-line

(factory) PD testing of rotating machine

high voltage insulation.

HVPD offer a number of on-line PD test and

monitoring solutions for in-service testing of

oil, solid, and gas insulated transformers.

HVPD’s on-line PD screening of medium

voltage (3.3 to 45 kV) and high voltage (66

kV+) transformers gives pr e-qualification of any dangerous discharges emanating from

within the main MV/HV windings and/or the

accessories attached to the transformers.

Early-life on-line PD testing of the motors

for a power generation company

HVPD performed on-line testing on 3x

6.6 kV water pump motors from twodifferent manufacturers. Baseline

spot-tests produced an assessment of the

present insulation condition of the stator

windings and provided a basis for future

PD trending.

HVPD Longshot™ results indicated that

one of the manfacturer’s motors had stator

winding insulation in the ‘Unreliable’

condition category.

Our client filed a warranty claim with

the manufacturer, based on inadequate

design of the stator winding. Two separate

third party off-line PD tests backed up our

findings and the motors were rewound

and repaired under warranty.

Case study Case study

On-line PD testing of a generator

transformer

Following a failure in the 275 kV generator

conecting link in a transformer, the cable

and sealing end were replaced. On-line

measurements on the transformer and

repaired HV connecting link were carried

out at the commissioning stage.

HFCT sensors were attached around

the earth connections of the HV cable and

TEV probes were used to perform the

time-of-flight measurements to locate the

PD events. PD was identified and traced to

support insulators on the blue phase

connecting link between the HV cable

sealing end and the transformer output

bushing. These were then repaired and

the transformer, retested for PD, passed

as suitable for service.
