Current transformer is used to step down the higher current in primary and
protects the measuring instruments against high currents. Low Voltage
Transformers are used for supply to measuring instruments & protection devices
of electrical switchgear and control gears installation. They are suitable for
system voltage 415/660V & Frequency 50/60 Hz. These Current Transformers are
designed for a secondary current of 1A or 5A and the primary current ranging
from 5A to 7500A depending on the application of the system load current.
Analog Meters are used in panels to measure electrical parameters like current,
voltmeter, power factor, frequency etc.They display values on a dial, usually
with a moving pointer or needle.
Digital panel meters
Digital panel meters measure and display processes and electrical variables via
an alphanumeric digital readout.Enza digital panel meters are used for
measurement and analysis of wide range of electrical parameters.
An earth leakage relay is a device used to sense earth leakages and open a
circuit breaker when the leakage current exceeds the preset value. It can
protect human beings from electrocution and prevent fire hazards. Earth leakage
relays are used in combination with Core balance current transformers (CBCT) or
zero phase current transformer (ZCT). Earth Leakage Relay is an industrial grade
control device used for protection purposes. The main function of the ELR is to
monitor the circuit for leakage / ground fault current and trip in case the
leakage current exceeds the set point.
Under voltage relays
A relay that has contacts that operate when the voltage drops below a set
voltage. Undervoltage relays are used for protection against voltage drops, to
detect short-circuit faults, etc. The main function of the relay is to sense or
detect the abnormalities in the circuit and to send a message to circuit breaker
to break the circuit. In case of undervoltage relay if the voltage in the
circuit or system is less than prescribed value it will disconnect the circuit
with the help of circuit breaker.
Star delta timer
star-delta timing relay is used for start-up control of three- phase motors. The
time in star operation is continuously adjustable in the respective time range.
As standard, the device is offered in 4-time ranges and 3 contact changeover
times.
