APPLICATION:-

• Protective devices such as overload relay, short circuit relay, circuit breakers and CTs etc must be checked and calibrated regularly to ensure that they are always ready to operate correctly if a fault occurs in the system which are protecting the system from damage. Routine current injection testing sets will help in quickly detecting faulty or incorrectly adjusted protection circuit I device and thereby avoid damage to the system. The unit ensures protective circuit I devices function correctly. With the help of current injection test unit the correct functioning of protective device I circuit is ensured.
• The primary current injetcion testing checks all parts of protection system by injecting current drawn by system the cable/busbars. It ascertains the current carrying capacity of any conductor, connector or calibration of CTs/bimetallic relays. The units are available in single phase version for small capacity and single or two phase version for higher capacities.

FEATURES:-

• Built - in Analogue Ammeters (Digital Meters on request)
• Time Interval measurable from .0001 sec to 999 secs (auto ranging facility) - Optional
• Continuously variable outputs.
• Panel with easy and clear readable legends.

DESCRIPTION:-

• These are basically two phase motors. Two-phase supply is normally not available, hence to operate the motors from single phase AC supply, second phase is artificially created by inserting a Capacitor and Resistor combination in series with one of the motor phase windings. Suitable combination of Capacitor and Resistor assembly is supplied along with the motor. The speed of revolution is 60 RPM at 50Hz. Instant stop & reversibility are achieved by means of a single-pole, double throw switch with center OFF position.

FEATURES:-

• Instant start & stop
• The motors have permanent magnet on the toothed rotor. The rotor is locked with matching teeth on stator, as soon as power is switched OFF.
• Starting & running current are same.
• Maximum Torque is 15 to 20% higher than nominal torque.

DESCRIPTION:-

• These Rectifier units are suitable for all electro deposition processes within their rating. The widest applications in the field require maximum voltage of 8V, 12V and 20V D.C. at various current capacities as per requirement.

DESCRIPTION:-

• Servo - Controlled Automatic AC Voltage Stabilizers of 'AE' make are of 'Electro - Mechanical (EMS) type. The purpose of voltage stabilizer is to receive a fluctuating AC voltage of large amplitude & deliver an almost constant voltage, which remains within a very narrow band (± 1%) of the nominal voltage - quality of the AC voltage remains unchanged.
• The voltage variations, which have become a common phenomenon in current power supply system, cause havoc in modern complicated & sophisticated equipments. The voltage stabilizers are meant to take care of this problem & protect the equipments. They ensure longer life of the equipments & also drastically cut down electricity consumption of equipments leading to continuous reduction in electricity bills. Thus, they play an important role in energy conservation which is need of the day.

DESCRIPTION:-

• The stabilizer consists of a multiple tap auto transformer and solid state control circuit This maintains the output village within ± 12% of nominal voltage for large variations in input voltageI. These can be used for Air conditioners, refrigerators, lights loads etc.

FEATURES:-

• Tripping of output village during under voltage and overvoltage conditions.
• Provision of time delay after startup, under voltage cut of and over voltages cut of conditions.
• In case time delay is not required, then the stabiliser can be switched on by pressing the instant Start push button provided on the front side.
• Compact and light weight.
• Provision of status LED's for input ON, input On equal voltage (low) and input voltage (High) on the front side.

AE Manufactures Test bench units Which can be used for several Application of which few are mentioned below:-

Ordering Information:-

• Unit under test
• Complete technical specifications of the unit under test
• Mechanical dimensions of the test bench desired
• Type of meters required - Analog / Digital
• Any other specific features

RANGE OF MANUFACTURE:-

• Tapewound ring type current Transformers with and without mounting arrangements.
• Tapewound ring type CTs with sealing arrangements.
• Tapewound wound primary CTs (WPL)
• Resincast (epoxy) BPL CTs.
• Resincast (epoxy) wound primary (WPL) CTs.
• Bushing CTs (Fibreglass taped).

CORE BALANCE CTs (Resincast):-

• These are used in detecting earth faults of very small magnitude. A three phase cable is passed through these CTs & the unbalanced currents in the three phases set up a differential flux giving rise to a current on the secondary side of these CTs sufficient to actuate a relay.

INTERPOSING CURRENT TRANSFORMERS (Resincast):-

• Used in matching the ratios of main feeder CTs for differential protection schemes. These also find application as saturable CTs used in conjunction with main feeder CTs and thus protect the meters connected to these by limiting the current flowing through the meters.
