Medium Voltage Switchgear IEC standard

We provide IEC (International Electrotechnical Commission, European standard)  type tested medium voltage switchgear from 2 manufacturers. One is GE Secogear from Shanghai, China and the other is Siemens from either Jarkata, Indonesia or from Thailand. There can be air insulated switchgear (AIS) using air as insulation medium for all the busbars and MV components (like CTs, PTs, support insulator, earthing switch) or can be gas insulated switchgear (GIS) using SF6 gas as insulation for all busbars and MV components. There is also the option for better environment we culd use 50% SF6 + 50% N2. This latter can also devided as per the light duty (we call Ring Main Unit) and heavy duty (we call Gas Insulated switchgear GIS). The circuit breaker is vacuum type circuit breaker that use vacuum as a switching medium.

The switchgear can be equipped with any protection relays from any maker, like GE Multilin, Siemens Siprotec, Alstom and etc. The switchgear can be equiped with arc protection devices like VAMP or ABB. The Substation control system can also implement in the switchgear using intelligent relay protection set. The switchgear can also be equiped with special windows for Thermal image scanner to check the fit busbar connections.

We will do all the design work i.e. single line diagram, foundation layout, panel layout, schematic diagram, wiring terminal list. we can also do relay setting coordination study providing that the network data received from the customer.

After delivery, we could provide installation and commissioning for them. The standard warranty is 1 year with the option to extend it to 3 years.

We have experiences working with the sophisticated consultant like Foster Wheeler, Technip and etc. the documentation required is not concern us.

The rating of the IEC standard switchgear are as follows;

The rating that is rarely find from the market is 24kV and 31.5kA can be quoted by us.

 We could also provide medium voltage switchegear with marine certificate.

For Ring Main unit we could provide 630A 36kV rating.

 The gas insulated switchgear can be IEC or GB standard

Retrofit solutions of the obsolete GE PowerBreak I
50kA, 2000A, 3000A, 4000A
replace with the next generation UL approved GE PowerBreak II or GE Mpact Air Circuit Breaker
or just change the already aging RMS9 trip unit to EntelliGuard TU trip unit

We could survey the ACBs on site and advise the appropriate option.

3 possible solutions are;

Solution1  is to retrofit the GE PowerBreak I to GE PowerBreak II Air Circuit Breaker (ANSI/UL) and conversion kits. This option is with higher cost. The fact is that GE PowerBreak is the most durable Air Circuit Breaker (UL standard calls Insulated Case Circuit Breaker). This new PowerBreak II will be last 2 time longer than the IEC Air Circuit Breaker in the market. From the records of PowerBreak I, the Circuit Breaker upto now is average 17-20 years old and still running good.

 Solution 2 is to retrofit the GE PowerBreak I to GE Mpact Air Circuit Breaker and conversion kits. This is the econonical solution in a short term. If consider long term at the time span of 15 years, the solution 1 is with lower cost, lower outage over 15 years.

      Solution 3 to change the trip unit RMS9 of GE PowerBreak I
      with the new EntelliGuard TU Trip unit and conversion kits.

The work shall be completed in a night in Bangkok for retrofit of 3 sets PowerBreak I. This includes testing and commissioning of the new replacement. The relay setting coordination study and setting value input can also be done optionally.

P.S. the Entelliguard TU Trip Unit and its conversion kits can also be used for other old ACB i.e. GE AK/AKR, GE WavePro, Allis Chalmer, I-T-E, Westinghouse

Online Partial Discharge Monitoring for Rotating Machine

Sparks Instruments SA, MC-monitoring SA , Switzerland

Advance notice the conditions of your generator or large motor's insulation for very effective preventive maintenance. Much reduce unplanned shutdown.

The system will get online the high frequency signal from the high voltage power of the generator or large motor and this high frequency signal can be the indicator for partial discharge level in each certain part of the generator or motor. At a certain level of partial discharge that we get online from the system can be used to plan the inspection or overhaul the generator or the large motor. it is for Hydro Generators, Turbo Generator, Wind turbine, industrial Motors.

The system comprises of 1000pF high voltage Coupling Capacitor to get all the target frequency from the high voltage level and the signal is fed into the Partial Discharge Online Monitoring unit. The unit will show the instant Partial Discharge information. it also record the information and create a trend for projection. The information can be viewed from the LCD screen of the unit or can be download to a notebook PC. in addition the information can be conneccted online to the data storage server for later analyse. The information can also be communicated via SCADA. Many units of Generators and/or Motors can be monitored separately and send all the information to the data storage server.

Coupling Capacitor 24kV rms 1000pF for online partial discharge monitoring

Key Features -Norminal voltage 24kV rms -Build in Quadrupole with voltage reference output -Build in Overvoltage Protection -Capacitive floating Signal output to avoid Eddy Current Loops

There is a case that the Coupling Capacitor cannot be used as their electrical connection point is close to the surge absorbing capacitor of the generator, then the high frrequency current transformer (HFCT) shall be used. The system connection is the same as the coupling capacitor.

The online partial discharge monitoring unit can be a portable one or a permanent installation in a junction box nearby the coupling capacitor

 Sparks Instruments offers the unique 3 phase simultaneous measurement of the partial discharge online monitoring that can monitor the end winding section of the generator. this system mesure partial discharge signal between phase to phase not only phase to ground. the extended local display is below;

in addition, Sparks Instruments offers the various effective noise rejection method so that the partial discharge pattern cen be viewed clearly without noise from the system

Many Generators or Motors' partial data can be fed into the central station for comparison and stored for analyse. the system can be communicated to SCADA.

This Partial Discharge Online motoring system will supervise the insulation of the winding of the generator and/or large motors. There is another effective and benefitial tool to indicate in advance the rotor interturn short circuit using what we call Air Gap Flux Probe.

Apart from this Partial Discharge Online monitoring system for Generators and Large Motor (rotating machines) , Sparks Instruments also offer the instulation and condition monitoring system for large transformer, high voltage gas insulated switchgear, underground installation high voltage cable, high gas insulated busduct and also medium voltage switchgear.

The other part that we would like to introduced together with the above monitoring is the Airgap Flux probe for early detection of short circuit in the inter-tuen of the rotor in the generator and also Insulation and condition monitoring for high voltage equipments. Pls click,

For Thai, link below provides some more information on Partial Discharge.

Airgap Flux Probe detecting Short Circuit Inter-turn of Rotor of Turbo Generator

Sparks Instruments SA, MC-monitoring SA , Switzerland

For Hydro Generators, Turbo Generator, Wind turbine, industrial Motors

The airgap search coil designed and manufactured by Sparks Instruments SA and is used to detect faults in the rotor winding insulation of turbo generators. The body is made from fiber glass and the sensing element is encapsulated within high temperature epoxy resin. AS many machine designs are different, the ASC sensor is typically designed especially for each type of the machine.

The probe is installed on the wedge within the airgap between rotor and stator and the integrated small high temperature cable allows and easy routing outside of the machine. The open wires allows to lay also the cable through the ventilation holes instead passing it through the endwinding section. The probe measure the variation of the magnetic flux created from each rotor coil. It withstand up to 2 Tesla and is designed to operate for more than 155 degree C. The high temperature signal cable can be permanently used for upt o 155 degree C. If longer signal cables than 10m are required, the probe is delivered with a signal driver.

The acquisition and monitoring unit UDL-8000 is to monitor the high voltage insulation systems. It is a multi-modular system wuth central CPU controller, arious different signal conditioning modules and sensor interfaces (upto 8 modules per controller) and application specific software package. They are used for acquisition, evaluation and monitoring of the rotor flux of turbo generators.

The rotor flux is measured by the ASC-2000 series flux sensor installed within the airgap of the generator. The Flux sensor are connected to this UDL-8000 unit. The module offers the interface for the reference sensor or reference source. Two flux sensors and five 4-20mA analogue inputs for the acquisition of the machine operation condition.

The system using the signal response of each rotor coil and compare it with the coil response of the coil from the opposite pole a partial short turn or complete short turn can be detected

 The sytem can be integrated in one system and communicated to all the condition monitoring devices.

Please see on the menu for Online Partial Discharge Minitoring System for further protection of your generator and motors. There is also the information on Insulation and Condition monitoring of High Voltage equipments
