When the protection relay is operating under
the conditions specified in the section "Technical data", the relay is practically maintenancefree. The relay modules include no parts or
components subject to an abnormal physical or
electrical wear under normal operating conditions.
If the environmental conditions at the relay
operating site differ from those specified, as to
temperature, humidity, or if the atmosphere
around the relay contains chemically active gases
or dust, the relay ought to be visually inspected
in association with the relay secondary test or
whenever the relay modules are withdrawn from
the case. At the visual inspection the following
things should be noted:
- Signs of mechanical damage on relay modules,
contacts and relay case
- Accumulation of dust inside the relay cover or
case; remove by blowing air carefully
- Rust spots or signs of erugo on terminals, case
or inside the relay
On request, the relay can be given a special
treatment for the protection of the printed circuit boards against stress on materials, caused by
abnormal environmental conditions.
If the relay fails in operation or if the operating
values remarkably differ from those of the relay
specifications, the relay should be given a proper
overhaul. Minor measures can be taken by personnel from the instrument work-shop of the
customer’s company, e.g. replacement of auxiliary relay modules. All major measures involving overhaul of the electronics are to be taken by
the manufacturer. Please contact the manufacturer or his nearest representative for further
information about checking, overhaul and
recalibration of the relay.
Note!
Numerical protection relays contain electronic
circuits which are liable to serious damage due to
electrostatic discharge. Before removing a module containing electronic circuits, ensure that
you are at the same electrostatic potential as the
equipment, for instance, by touching the relay
case.
Note!
Static protection relays are measuring instruments and should be handled with care and
protected against moisture and mechanical stress,
especially during transport.
