1. General
The HYDROCAL 1005 is a permanently-installed multi-gas-in-oil analysis system with transformer
monitoring functions. It allows for the individual measurement of moisture and the key gases hydrogen (H2), carbon monoxide (CO), acetylene (C2H2) and ethylene (C2H4) dissolved in transformer oil.
As hydrogen (H2) is involved in nearly every fault of the isolation system of power transformers and
carbon monoxide (CO) is a sign of an involvement of the cellulosic / paper isolation the presence and
increase of acetylene (C2H2) and ethylene (C2H4) further classifies the nature of a fault as overheating, partial discharge or high energy arcing. The device can serve as a compact transformer monitoring system by the integration / connection of other sensors present on a transformer via its analog
inputs:
5 analog outputs 0/4-20mADC
4 analog inputs 0/4-20 mADC (Option)
6 analog inputs 0/4-20 mADC +20% / 0-80 VAC +20% (option)
configurable by jumpers
It is further equipped with digital outputs for the transmission of alarms or the execution of control
functions (e. g. control of a cooling system of a transformer):
5 digital relay outputs
5 digital opto-coupler outputs (Option)
Key Advantages

2. Mounting of HYDROCAL1005 unit
2.1 Locations for installation of HYDROCAL1005
To ensure the correct function of the HYDROCAL1005 the location of mounting is very important.
For a typical transformer, four places are possible:
Pos. 1
On return side of cooling circuit:
Please install the unit on a straight piece of tube on the cooler output between the cooler
and the main oil tank. In order to avoid negative pressure, the unit must absolutely be
mounted on the downstream side (after the bend) of the oil circulation pump.
Remark: Choose this place only in case of continuous oil flux through the cooler.
Pos. 2
Flange below on the transformer tank:
The flange must be at minimum height of 40 cm in order to allow installation and mounting
of HYDROCAL1005 unit.
Pos. 3
Upper filling valve:
It is possible to mount the Hydrocal 1005 unit on this position, if the filling level of
the oil is min. 100 cm higher than the mounting position. This position is not recommended, because the filling process is influenced by the hydrostatic pressure of
the oil and it may be difficult to operate and read the data of the unit.
Pos. 4
Never install the HYDROCAL1005 unit on top of the cooler or on the suction face of
the pump. In this case, filling oil step cannot be carried out in the right way.
HYDROCAL 1005 Manual for Installation and Operation Page 6/111
2.2 Security precautions for installation
The following security precautions must be strictly observed during the installation. Otherwise no
warranty claims will be accepted.
Never remove the protection cap from the sensor before you are ready to
mount the unit on the valve of the transformer.
The protection cap protects the sensor against dust and other foreign bodies.
Additionally it protects the thread of the measuring head and/or adapters.
Note: Use the protection cap also after dismounting of the unit.
Never close the aeration holes for oxygenation. They are situated in bottom side of the protection cover and at the back plate of the device
Never use or stock chemicals with hydrocarbon contents near the measuring sensor.
Never clean the measuring head with solvents, because its gases will strongly
impair the measuring accuracy and the sensitivity of the sensors.
Never apply a negative pressure to the measuring head.
Negative pressure can cause problem during filling process.
Remove the HYDROCAL1005 unit from the valve every time you degas or
refill the transformer. You can also close the valve of the transformer
Never install the HYDROCAL unit on a valve that is closed for a long period of time. Remove the unit if this cannot be avoided. Please refer to
De-installation instructions
Never install the HYDROCAL1005 on the suction side of the cooling
pump!
The HYDROCAL 1005 should be installed on positions located 100 cm below of the oil level inside the transformer
Never install the HYDROCAL1005 unit on an elbow or curve of a tube.
The unit cannot operate by negative pressure produced by turbulences in
curves.
HYDROCAL 1005 Manual for Installation and Operation Page 7/111
Never install or remove the HYDROCAL1005 without opening first the
aeration screw.
Never use galvanized fittings or valves to mount the HYDROCAL1005
unit.
Galvanized fittings or valves can react with oil; this will produce incorrect
measuring values.
Never clean the HYDROCAL1005 unit with high pressure cleaning
equipment.
High pressure cleaning equipment used to clean transformers can seriously
damage the HYDROCAL1005 unit.
Never use a chaining key tool for mounting.
Use of such tools can damage the surface of the measuring head and the
threads. Please use an adjustable thin spanner for 1 ½“.
Attention!!!
Faulty or inappropriate handling of the sensor head like malfunction by
negative pressure, paint or solvent liquids make the warranty invalid.
HYDROCAL 1005 Manual for Installation and Operation Page 8/111
2.3 Preparation for installation
Before installation, a visual inspection of the unit must be carried out. Remove the protection cover
and check visually the components. All cables and tubes must be connected.
2.3.1 Power supply for the unit
The HYDROCAL1005 unit requires an auxiliary power supply of 110 / 230V close to the unit. The
power needed is max. 350 VA.
2.3.2 Requested tools:
Long Allen key, size 4 for aeration screw
Bucket, oil absorber, cleaning rag
Teflon-band
Drill / screw driver
Digital multimeter
Tin spanner M55 or adjustable tin spanner of 1 ½“ for valve and fittings
To seal the thread of the measuring head, either Teflon band (minimum 4 to 5 layers must be applied) or an O-Ring must be used.
2.4 Installation of the HYDROCAL1005 unit
Attention!!!
Mount the unit horizontally on the valve. The aeration screw must be in
the 12 o’clock position.
Please mount the HYDROCAL1005 unit on a valve with full opening (full bore valve) or a ball valve
with an internal thread of 1½” (DIN ISO 228: G 1½) . The HYDROCAL unit has a 1½’’ thread (Dimensional drawings, see. chapter 8). As an option a valve with NPT 1½ standard can also be used.
A good oil flux should exist on the mounting location. If necessary, use a reduction piece (adapter).
It is recommended to mount the HYDROCAL 1005 unit to valve with a union- or sleeve nut. In this
case the device has not to be turned to fix during the installation. An O-ring should be used as sealing.
In case there exist strong vibrations on the mounting valve, the valve should be relieved by a support.
Then mount the unit according to the following steps:
HYDROCAL 1005 Manual for Installation and Operation Page 9/111
Only remove the protection cap (slowly while turning)
when you are ready to mount the measuring head!
Clean the internal side of the installation valve.
In case you don’t use a union or sleeve nut as connection point with o-ring, wind 4 to 5 layers of
Teflon band on the Hydrocal 1005 connection thread and mount it either directly into the valve or
into an additional adapter. If you use an adapter it should be mounted to the valve, before the Hy-
drocal 1005 will be mounted to the adapter. Wind 4 to 5 layers of Teflon band on the thread of the
adapter and mount it into the valve. Make sure that everything is fixed mechanically.
Turn the unit in order to get 12 o clock position.
HYDROCAL 1005 Manual for Installation and Operation Page 10/111
Attention!!!
The following steps must be done according to the company procedures.
Work carefully in order to prevent air entering into the transformer. Use a
bucket to catch oil coming out as described on following drawing.
Unscrew the aeration screw 3 – 4 turns with Allen key No. 4. (Aeration is active).
Open the valve slowly until oil comes of the sample tube.
As soon as no air bubbles sort on the sample tube, close the aeration screw. Then fully open the
valve. Remove the oil from the measuring head externally.
Do not use any solvents for cleaning!

4. Software on HYDROCAL unit
4.1 General information
The gas-in-oil analyzer HYDROCAL1005 is based on a microprocessor controlled measuring system. A 32 Bit „Coldfire“ processor with a clock frequency of 240 MHz (bus clock 80 MHz) is used.
The software has been developed with the language „C“. The system has a flash memory of 16 / 32 /
64 Mbyte for measuring data. This offers approximately 2 / 4 / 8 years time storage capacity for the
measuring data.
After this period, the oldest data will be overwritten by the latest values. When using additional external sensors, the storage capacity depends on the number of sensors and the time interval selected
for storage. The following formula can be used to determine the storage capacity (in the example 64
Mbyte is used):

Also an additional reduction of the storage time takes place by the definition of alarms. Each change
of alarm status requires 12 Bytes.
Attention: To avoid any loss of data, it is proposed to read out regularly
the measuring data by the Windows based software “HydroSoft”.

4.3. Operation Cycles
This chapter describes each process steps and provides information in regards to the safety functions as
well as how to reset errors. The consequence of all errors is that the cycle will be interrupted immediately and
all valves will be closed.
For all observed errors, you can acknowledged them by pressing button ..
If nothing changes, check status of all components according to actual cycle.
Check that all tubes go straight into the FESTO quick screws and any oil/air leakages have appeared
Check that cables and all pins of the plug go straight into their socket; pushing the plug in carefully.
