INTRODUCTION

Every electrical apparatus or machine Is provided with insulation between live part and earth or between two different sections of live parts. This insulation is required to be tested at high voltage values recommended by applicable relevant standards. The standard Specification for various electrical apparatus specifies Power Frequency Voltage withstand test at different levels depending upon working voltage of electrical apparatus. It is observed from the various standards for electrical equipments that the minimum power frequency voltage withstand test level for electrical insulation is 2kV for one minute. We have, therefore, standardized on manufacture of'AE' High Voltage Breakdown Testers with rated voltage of 5kV.

High Voltage Tests Sets of higher voltage upto 600kV are also manufactured against specific requirement. The standard voltages are 10kV, 15kV, 20kV, 25kV, 30kV, 50kV,100kV, 150kV, 200kV & 300kV. The test sets uplo 30kV are manufactured in Air Cooled design while the sets of 50kV & above are manufactured in Oil Cooled design. The output of these high voltage testers is single phase 50/60Hz. The standard H.T. current rating of air-cooled design as also of oil cooled design upto 150kV is 100mA for 30 minutes. For voltages ranges above 'AE' make 5kV A.C. (with 2.5kV tap) High Voltage Breakdown Tester is portable, sturdy & plug in to start type construction & requires minium table space. It broadly consists of 3 main sections. 1) High Voltage Transformer 2) Variable Voltage Source 3) Control Circuit

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.

DESCRIPTION

It is used to measure the applied frequency, functionally similar to vibrating reed meter. The meter incorporates light emitting diodes LEDs which are used instead of vibrating reeds to indicate applied frequency. The frequency is determined by blinking LEDs. When applied frequency matches with the frequency marked on the dial, that particular LED blinks with maximum intensity. When the applied frequency is mid way between two adjacent LEDs, both LEDs blink. When the meter is switched on all the LEDs glow sequentially for a period of 1 to 1.5 seconds, thereafter it will indicate the applied frequency.

All voltage ranges are available in single meter. Terminal screws with washers are provided only for specific voltage as per requirement & remaining two terminals are covered with insulated caps.  In case of 96mm & 144mm instruments, two sets of LEDs with the same scale range can be offered, giving two independent meters in one casing (Dual Scale). This facilitates in comparing the frequency of two voltage supplies for paralleling operation.

DESCRIPTION

It is used to measure the applied frequency. Vibrating Reed Frequency meters indicate the supply frequency by means of individual reeds, when rated voltage ± 20% is applied across the terminals of the meter, the particular reed, whose natural frequency of vibration coincides with the supply frequency, vibrates with full amplitude. In case the supply frequency falls midway between two reeds both the reeds vibrate, at reduced amplitude. The amplitude of vibration at the tip of reeds is high enough for a distinct indication.  The instrument can be operated at 110V, 220V, or 440V. Terminal screws with washers are provided for the selected operating voltage & remaining two terminals are covered with insulated caps. In case of RFD96 and RFD144 instruments, two sets of reeds with the same scale range can be offered, giving two independent meters in one casing. This facilitates in comparing the frequency of two voltage supplies for paralleling operation

DESCRIPTION

'AE' SYNCHROSCOPE is categorized into two types A) Electro-mechanical and B) Electronic.

 

ELECTRO-MECHANICAL TYPE

It incorporates a POINTER and LED to indicate synchronising condition. If the generator- (II) frequency is higher or lower than that of mains- (I) the pointer rotates in clockwise or anti-clockwise direction respectively. The speed and direction of rotation depends upon difference in frequencies, which guides the operator to speed-up or slow-down the generator. Synchronising condition is determined by dark lamp method, wherein the pointer coincides with synchronising mark and the LED does not glow. The LED glows in accordance with difference in phase, frequency and amplitude of voltages. When the pointer is towards the bright LED, it indicates the antiphase condition.

DESCRIPTION

Maximum Demand meter is used for monitoring thermal loading in Power Distribution systems, Networks, Machines etc. It indicates maximum loading current over a period. Short-period current peaks are not registered but long overloads are registered.  In the Maximum Demand meter the measuring current flows through the bimetal spiral which is temperature sensitive. The free end of the spiral is connected to a black measuring pointer. The moving system is activated by heat generated by the current flowing through the spiral. The instrument is provided with an additional red slave pointer with a higher friction, which makes it to remain at its maximum position, which determines the maximum average loading current. The high torque of metallic movement drags the red pointer along with the black pointer. The red pointer remains stationary at the maximum value reached. This can be reset by rotating the knob provided on front facia. To prevent false indication due to fluctuations in ambient temperature, an additional bimetallic spiral is wound in opposite direction, which is mounted on the same spindle to compensate variation in temperature from -10 to + 55 degrees Centigrade. Frequently there is a need to measure instantaneous current simultaneously & hence moving iron movement having the same range is incorporated in the same meter.

 

FEATURES
•	RMS measurement of maximum current.					•	20% overload capacity.
•	Long current peaks are registered.					•	Instantaneous current measurement.
•	Red pointer to indicate maximum current reached.					•	Sturdy movement.
•	Analogue Indication.

SELECTION OF RANGES

Upper limit of measuring range for meters shall be one of the following values -

1, 1.2, 1.5, 2, 2.5, 3, 4, 5, 6, 7.5, 8 or their decimal multiples.

Example for selection of proper range

1 ) Formula for 1 Phase active power

P(max) = VI COS¢ Where COS¢ = 1.

If Voltage = 500V & Current = 2.5A calculated power = 500 x 2.5 x 1 = 1.25kW.

If the calculated value is 1.25kW 0 - 1.2kW or 0 - 1.25kW shall be selected as a range for power.

2) Formula for 3 Phase active power with PT & CT.

P(max) = √ 3VI COS¢ x PTR x CTR Where COS ¢ = 1.

If Voltage = 110V & Current = 5A PTR = 400kV/110V CTR = 1000A/5A

calculated power = √ 3 x 110x5 x (400x1000/110) x (1000/5)= 692MW.

If the calculated value is 692MW  0 - 600MW or  0 - 750MW shall be selected as a range for power.

 

Note :
•	All Wattmeters are calibrated at cos¢ = 1 and Varmeter at sin¢ = 1
•	All Low Power Factor Wattmeters are calibrated at cos¢ = 0.2 lag.
•	Voltage & Current range other than specified can be supplied on request, if feasible.
