ADD
Online Direct Contact PD Test System
The ADD allows online partial discharge detection on medium voltage accessories such as: Arresters, dry
type transformers , bushings, insulators, etc... The partial discharge level is displayed by visual and audible
indicators. The remote display module also allows to read the levels from a great distance for maximal safety.
EASY TO USE
FEATURES
t Three levels default indication
t Two zones (scale of default)
t Visual and audible indication
t All-Check self-test for verifying proper tt
t operation prior to use
The ADD operation is quite simple. The probe is

CORONA EFFECT INCLUENCE
t Lightweight design
The ADD efficiently filters the influence of corona
type activity thus making it an ideal tool to detect
insulating material internal partial discharge.
t Built-in universal hotstick adaptor
t Powered by 9V alkaline battery
t Special design for HV live contact
SAVE TIME AND MONEY
ADD instrument installed
on a hotstick
The ADD is designed to detect partial discharge
in medium voltage components by direct contact
on energised conductors. We developed a contact
method using ultra wide band radio frequency
detection technology. Using the ADD on a regular
basis will help you to prevent failures, customers
complain and costly investigation to identify the
source of a problem or potential problems.
Hook and Y type
probes are available
