C&S Electric Limited
Introduction
In the family of protection relay, CSDPR-V2-300 is numeric multi powered Over-current
relay specially designed for ring main units & feeder protection. It combines the following
functions in one unit:
u Over current, Short Circuit, Earth Fault & Earth Fault High set protection
u DEFT & Inverse characteristics for O/C and E/F individually selected for
phase & earth fault
u Wide operating ranges of the auxiliary supply voltage (AC/DC)
u Remote trip *
uSwitch on to fault (SOTF) protection
u Remote protection block input DI*
u Potential pulse output for direct triggering the circuit breaker coil
u Potential free alarm contacts available
u Unbalance/ Asymmetric protection
u Circuit breaker failure protection
u Harmonic blocking (via DFT Filter) to avoid any unwanted tripping
u Two sets of setting groups
u Last 5 Fault and 10 Event record with Time stamp
u RS-485 Modbus
u USB port for PC / Laptop interface
Design
Relay will get energized from any of the following available sources:
u Aux. supply
u CT current
u Internal battery
u USB port
Relay will operate its trip contacts only when CT current is present or Aux. supply is available,
with other power sources, only the relay display/HMI will be available.
In the absence of Aux supply/Battery voltage/USB, LCD will get energized, if CT current is
10% of rated current or above. Trip coil will be operated, if CT current in single phase is at
least 20% of rated current or 15% of rated current in three phases. Relay is not powered from
Earth CT, so for earth fault protection, phase current is mandatory.
The disposal of our products and possible recycling of their components after
decommissioning has to be carried out by an accredited recycling company or
the products/components must be taken to applicable collection points. Such
disposal activities must comply with all local laws, guidelines and
environmental specifications of the country in which the disposal is done.
Our products and batteries must not be disposed of as household waste. For disposing
batteries it is necessary to observe the local national/international directives.
According to national legislation, penalties may be charged for incorrect disposal of
such waste.
By disposing of these products correctly you will help to save valuable resources and prevent
any potential negative effects on human health and the environment.
